Article Summary: A brass cable gland is one of the most critical components in any electrical installation — the point where a cable enters an enclosure, where protection is either secured or lost. This guide covers everything an electrical engineer, procurement officer, or project manager needs to know about brass cable glands: what they are, why brass is the dominant material, what types are available, which standards apply, and how to choose correctly. Throughout, we highlight why Cabex India — a certified brass cable gland manufacturer supplying the UK, Europe, Australia, the Middle East, and India — is one of the most trusted sources for this product category globally.
What Is a Brass Cable Gland? The Essential Explanation
A brass cable gland — also called a cable connector, cable fitting, or cable entry device — is a precision-machined mechanical component used to anchor, seal, and protect electrical cables at the point where they enter an enclosure, junction box, control panel, switchboard, or piece of electrical equipment.
It performs four critical engineering functions simultaneously. First, it provides mechanical retention — gripping the cable firmly so that no external force, vibration, or accidental pulling can dislodge the cable from its termination inside the equipment. Second, it provides environmental sealing — compressing an elastomeric seal around the cable’s outer sheath to prevent ingress of moisture, dust, oils, and other contaminants, thereby maintaining the enclosure’s IP (Ingress Protection) rating. Third, it provides earth continuity — in armoured cable installations, the gland clamps the steel or aluminium wire armour, completing the earth bonding circuit between the cable armour and the equipment enclosure. Fourth, it provides strain relief — distributing any tensile or bending forces on the cable across the gland body rather than allowing them to reach the internal cable terminations.
According to the Global Metal Cable Glands Market Report 2026, the global cable glands market was valued at USD 2.18 billion in 2025 and is projected to reach USD 3.02 billion by 2032, growing at a CAGR of 5.7%. This growth is driven by expanding industrial infrastructure, oil and gas projects, renewable energy installations, and increasingly stringent electrical safety regulations worldwide. Within this market, brass cable glands represent the dominant product category by volume — preferred by electrical engineers globally for their combination of conductivity, strength, machinability, and cost-effectiveness that no other material yet matches in the general industrial category.

Why Brass Is the World’s Most Popular Cable Gland Material
The cable gland industry offers products in four primary materials — brass, stainless steel, nylon/PVC, and aluminium. Each has a legitimate place in the specification library. But brass consistently accounts for the largest share of global cable gland procurement. Understanding why helps procurement engineers, project engineers, and electrical contractors make more confident material selection decisions.
Electrical Conductivity — The Engineering Foundation
Brass is an alloy of copper and zinc, with copper content typically ranging from 60% to 80% depending on the grade. Copper is the benchmark of electrical conductivity in the engineering world. This copper content gives brass cable glands a natural advantage in earth bonding applications — when a gland clamps onto steel wire armour (SWA), the electrical continuity from the armour through the gland body to the equipment enclosure is highly effective, minimising earth loop impedance in fault conditions.
This matters enormously in industrial installations. IEC 60364-5-54 and BS 7671 both require that the earth continuity provided through cable gland terminations meets specific impedance thresholds. A brass gland — with its inherent conductivity — consistently meets these requirements without additional earth bonding straps in most standard SWA termination configurations.
Machinability — Precision Without Compromise
Brass is one of the most machinable metals available in industrial manufacturing. Its chip-breaking characteristics, low cutting forces, and excellent surface finish allow the precision machining of the fine threads, tapered cones, and close-tolerance sealing surfaces that a cable gland requires. A typical brass cable gland body is manufactured to tolerances of ±0.02 to ±0.05 mm across critical sealing surfaces.
This machinability directly translates to product quality and consistency. It is why Jamnagar, Gujarat — India’s precision brass manufacturing capital — houses the highest concentration of cable gland and brass component manufacturers in the country. Cabex India, established in this tradition of precision brass engineering, manufactures cable glands to exact dimensional specifications that guarantee consistent IP rating performance across every unit produced.
Corrosion Resistance and Surface Treatment Options
Natural brass provides moderate corrosion resistance suitable for most general industrial indoor and outdoor environments. For applications requiring enhanced corrosion resistance — marine environments, offshore installations, chemical processing plants, and food industry applications — nickel plating applied over the brass substrate significantly extends service life by providing a harder, more chemically resistant surface.
Nickel-plated brass cable glands from Cabex India undergo an electrochemical nickel deposition process that produces a uniform, adherent coating of 5 to 20 microns thickness over the entire external surface. This coating resists salt spray (tested to over 500 hours per ISO 9227), provides natural lubricity for easier installation, and gives the finished product its characteristic bright silver appearance.
Temperature Range and Mechanical Performance
Standard brass cable glands operate effectively across the temperature range of -40°C to +300°C depending on the sealing elastomer fitted. The three most common elastomers used in Cabex India brass glands are EPDM (Ethylene Propylene Diene Monomer) for general use in the range -40°C to +100°C, Neoprene for oil and fuel resistance applications, and Silicone for high-temperature applications up to +250°C. This temperature flexibility makes brass cable glands suitable for everything from cold-store electrical installations to cable terminations on heat-generating industrial machinery.

Manufacturing Quality — Precision Engineered, Rigorously Tested
Every Cabex India brass cable gland begins as high-grade brass rod — manufactured to BS EN 12164 CW614N or equivalent, with precise copper and zinc content to ensure consistent machinability, conductivity, and corrosion resistance across every production batch. Machining is performed on CNC lathes to close dimensional tolerances, followed by surface treatment (nickel plating where specified), elastomer seal fitting, and quality inspection.
Finished products undergo ingress protection testing in accordance with IEC 60529, tensile pull-out testing to confirm mechanical retention, electrical resistance measurement for earth continuity verification, and dimensional inspection against product drawings. Only glands that pass 100% of these tests leave the Cabex India facility. This rigorous approach is what makes Cabex India a preferred source for international buyers who cannot afford failures in field-installed products.
International Standards Compliance — What It Means for Your Project
The three primary standards governing Cabex India’s brass cable glands are: BS EN 62444 (the harmonised European/International standard replacing BS 6121:Part 4), the current global benchmark for cable gland testing including IP rating verification, pull-out force, and mechanical endurance; IEC 62444, the identical International Electrotechnical Commission standard accepted by national bodies in India, Australia, the Middle East, and across Asia; and BS 6121:Part 1:1989, the British Standard specifically covering SWA (Steel Wire Armoured) cable terminations that remains a contractual requirement on many UK, Middle East, and Commonwealth infrastructure projects.
For hazardous area installations, Cabex India’s explosion-proof and flameproof brass cable glands carry ATEX certification (mandatory for Zone 1 and Zone 2 installations in Europe) and IECEx certification (the international equivalent accepted in Australia, Middle East, India, and globally). These certifications are not self-declared — they are issued by accredited third-party certification bodies following rigorous type testing.

The BW/CW Gland Range — BS 6121 Compliance for UK & Commonwealth Projects
Among Cabex India’s most internationally exported products is the BW/CW type brass cable gland range, specifically designed and certified to BS 6121:Part 1:1989 for armoured cable terminations on UK and Commonwealth projects. The BW gland (for cables with an inner covering) and CW gland (for cables without an inner covering) are the mandated termination types on thousands of UK infrastructure, marine, and export projects where the SWA cable standard prevails.
These glands are constructed with a compression cone and shroud arrangement that grips the SWA armour wires positively — providing both mechanical retention and the low-impedance earth path that UK installation standards require. Cabex India’s BW/CW range is fully dimensionally interchangeable with glands from other BS 6121-compliant manufacturers, making Cabex India a reliable alternative source for buyers who need consistent specification compliance without single-source dependency.
ATEX/IECEx Explosion-Proof Brass Cable Glands for Hazardous Areas
The oil and gas, chemical, petrochemical, pharmaceutical, and mining industries all share a critical requirement — that every electrical fitting installed in a classified hazardous area must be certified to prevent the ignition of flammable gases, vapours, or dusts. For cable glands, this means ATEX certification for European hazardous areas (Zone 1, Zone 2, Zone 21, Zone 22) and IECEx certification for international hazardous area applications.
Cabex India’s ATEX and IECEx certified brass cable glands are type-tested to the Ex d (flameproof) and Ex e (increased safety) protection concepts, meaning they are certified to contain any internal ignition without propagating flame to the external atmosphere (Ex d) or certified to prevent ignition through enhanced construction standards (Ex e). These are not ‘approved equivalent’ products — they carry genuine third-party certificates from accredited bodies and are verified in the international IECEx certificate database.

How to Select the Right Brass Cable Gland — A Practical Guide
Incorrect cable gland selection is one of the most common causes of IP rating failure and earth continuity faults in industrial electrical installations. The following systematic selection process — used by experienced electrical engineers — eliminates the most frequent errors.
Step 1: Identify the Cable Construction
The single most important selection parameter is whether the cable is armoured or unarmoured. Armoured cables (SWA, AWA, STA — Steel Tape Armoured) require a double compression cable gland that grips the armour layer. Unarmoured cables (PVC, rubber, LSOH outer sheath only) require a single compression gland. Using a single compression gland on an armoured cable creates a critical earth continuity fault — a mistake that routinely fails inspection and creates genuine safety risk.
Step 2: Measure the Cable Outer Diameter Accurately
After stripping the outer sheath back, measure the overall outer diameter of the cable including all layers at the point where the gland seal will sit. For armoured cables, measure over the armour. This measurement must fall within the cable range stated in the gland’s data sheet — the minimum and maximum outer diameters the gland’s elastomeric seal can compress down to reliably while maintaining the IP rating. Using a gland at the extremes of its cable range produces unreliable sealing results.
Step 3: Identify the Correct Thread Type and Size
The thread on the gland body must match the entry thread tapped in the enclosure panel. Metric is dominant in Indian, European, and most Asian installations. NPT is standard in American-influence installations (USA, parts of Middle East). PG threads are found in older German equipment. BSP is found in UK and Commonwealth panels, particularly on older installations and marine projects. Thread size is determined by the entry hole size — each thread designation corresponds to a specific tapping drill size and thread pitch.
Step 4: Confirm the Required IP Rating
Match the gland’s IP rating to the enclosure’s IP requirement. An IP65-rated gland installed in an IP68-rated enclosure creates the weakest point in the entire enclosure sealing system — the enclosure’s IP rating is limited to the lowest-rated component. Cabex India supplies data sheets for every gland type clearly stating the IP rating achieved under test conditions in accordance with IEC 60529.
Step 5: Check Hazardous Area Certification Requirements
If the installation is in a classified hazardous area (as defined in IEC 60079-10-1 for gas/vapour zones or IEC 60079-10-2 for dust zones), the cable gland must carry the appropriate ATEX or IECEx certification for the zone classification. Never install a standard industrial brass cable gland in a Zone 1 or Zone 2 area — even if it appears physically identical to a certified equivalent.

Frequently Asked Questions — Brass Cable Glands & Cabex India
The table below answers the questions engineers and procurement professionals ask most frequently when specifying and sourcing brass cable glands:
| Frequently Asked Question | Answer |
| What is a brass cable gland and what does it do? | A brass cable gland is a mechanical fitting used to secure and protect electrical cables where they enter enclosures, junction boxes, panels, and equipment. It provides strain relief, prevents cable pullout, seals against dust and moisture (maintaining IP ratings), and ensures earth continuity in metallic cable armour. Brass is the most widely used material globally because of its excellent electrical conductivity, corrosion resistance, machinability, and durability. |
| Why is brass the most popular material for cable glands? | Brass offers an unmatched combination of properties that make it the dominant choice globally: excellent electrical conductivity for earth continuity, natural corrosion resistance, high mechanical strength, outstanding machinability for precision components, and effective EMI/RFI shielding. It achieves IP68 ratings, handles temperatures from -40°C to +300°C in standard configurations, and is cost-effective compared to stainless steel for most applications. |
| What standards do Cabex India brass cable glands conform to? | Cabex India brass cable glands conform to BS EN 62444, IEC 62444, and BS 6121:Part 1:1989 — three of the most recognised international standards for cable glands. The explosion-proof and flameproof range carries ATEX certification (for European hazardous areas) and IECEx certification (for international hazardous areas). ISI certification covers domestic Indian market requirements. |
| What is the difference between single and double compression brass cable glands? | A single compression (unarmoured) cable gland has one seal that grips the cable’s outer sheath — suitable for unarmoured PVC, rubber, or LSOH cables. A double compression (armoured) cable gland has two seals: one that grips the cable’s steel wire armour (SWA) or aluminium wire armour (AWA) for mechanical retention and earth continuity, and a second that seals the cable’s outer sheath for environmental protection. Double compression glands are mandatory for armoured cables in industrial installations. |
| What thread types are available for Cabex India brass cable glands? | Cabex India manufactures brass cable glands in four international thread standards: Metric (M) — the global standard for IEC-based electrical installations in Europe, Asia, and India; PG (Panzergewinde) — the older German DIN standard found in legacy equipment; NPT (National Pipe Thread) — the American standard prevalent in the USA and Middle East; BSP (British Standard Pipe) — the UK and Commonwealth standard, used extensively in the BW/CW gland range compliant with BS 6121. |
| Does Cabex India export brass cable glands internationally? | Yes. Cabex India exports brass cable glands and related accessories to the United Kingdom, Europe, Australia, the Middle East, and the Far East. All exported products conform to the relevant international standards (BS EN 62444, IEC 62444, ATEX, IECEx) applicable to destination markets. Custom specifications including non-standard sizes, thread combinations, special surface treatments, and specific IP-rated assemblies are accommodated for large volume orders. |
| How do I select the correct size brass cable gland? | Measure the outer diameter of your cable including all layers (sheath, armour, insulation). Match this to the gland’s cable range specification — the range of outer diameters the compression seal accommodates. Select the thread size to match the entry hole in your enclosure and ensure the thread type matches your installation standard (Metric, PG, NPT, BSP). Using an undersized gland damages the cable; an oversized gland breaks the IP seal. Cabex India provides sizing charts and technical support for correct selection. |
