Introduction: Why Industrial Cable Glands Are the Backbone of Electrical Safety
In any industrial facility — whether it is an oil refinery, a chemical processing plant, a data center, a mining operation, or a large-scale manufacturing unit — electrical safety is non-negotiable. At the heart of this safety lies a small but mission-critical component: the industrial cable gland.
Industrial cable glands are precision-engineered mechanical fittings that secure, seal, and protect electrical cables as they pass through panels, enclosures, junction boxes, and equipment walls. They prevent cable pullout, provide environmental sealing against dust, water, and chemicals, and in hazardous environments, they stop the propagation of sparks and flames that could trigger catastrophic explosions.
Yet, despite their critical role, cable glands are often overlooked during procurement planning. The wrong gland — or a substandard accessory — can compromise an entire electrical installation, void certifications, and put lives at risk.
This comprehensive guide covers everything you need to know about industrial cable glands and industrial cable glands accessories — from types, materials, standards, and selection criteria, to installation best practices and why Cabex India (CabexIndia) stands out as one of the most trusted manufacturers and exporters in the world.
What Are Industrial Cable Glands?
An industrial cable gland, also referred to as a cable connector or cable fitting, is a device attached to the end of an electrical cable to secure it to the equipment it connects to. Its primary functions include:
- Strain relief — preventing the cable from being pulled or twisted out of position
- Environmental sealing — blocking ingress of moisture, dust, dirt, and corrosive chemicals (rated up to IP68 and IP69K)
- EMC protection — shielding against electromagnetic and radio-frequency interference
- Explosion protection — in hazardous areas, preventing ignition sources from escaping into explosive atmospheres
- Mechanical protection — preventing damage from vibration, abrasion, and thermal cycling
Industrial cable glands are manufactured in a variety of materials — brass, nickel-plated brass, stainless steel, and engineered plastics — to suit environments ranging from standard industrial settings to the most extreme hazardous locations.
Types of Industrial Cable Glands: A Complete Overview
1. Armoured Cable Glands (SWA/AWA)
Used with Steel Wire Armoured (SWA) and Aluminium Wire Armoured (AWA) cables, these glands clamp onto the armour to provide mechanical protection and earthing continuity. They are standard in power distribution, oil & gas, and heavy industry.
2. Non-Armoured Cable Glands
Designed for unarmoured cables, these glands rely on compression sealing to secure the cable and seal against environmental ingress. Widely used in control panels, junction boxes, and machinery.
3. Explosion-Proof (Ex d) Cable Glands
Built for Zone 1 and Zone 2 hazardous areas (gas), these flameproof glands prevent internal explosions from propagating to the surrounding atmosphere. Mandatory in oil refineries, chemical plants, and gas processing facilities.
4. EMC Cable Glands
Electromagnetic Compatibility (EMC) glands provide 360° shielding continuity for screened or braided cables, suppressing EMI and RFI. Essential in automation, instrumentation, and data communication applications.
5. Increased Safety (Ex e) Cable Glands
Used in Zone 1/2 hazardous areas where flameproof construction is not required, but additional safety measures reduce the likelihood of arcs, sparks, and excessive temperatures.
6. Stainless Steel Cable Glands
For highly corrosive environments — offshore platforms, food and beverage processing, pharmaceutical plants, and marine applications — stainless steel glands offer superior resistance to chemicals and corrosion.
7. Plastic/Nylon Cable Glands
Economical and lightweight, nylon glands are suitable for standard industrial and commercial applications where metal glands are not required. Available in IP68-rated versions for wet environments.

Industrial Cable Glands Accessories: A Deep Dive
Accessories are what transform a good cable gland installation into a great one. Poorly selected accessories are a leading cause of IP rating failures, earth continuity issues, and premature gland failure in the field. Cabex India‘s accessory range is engineered to work seamlessly with their cable gland portfolio.
Locknuts
CabexIndia’s locknuts are designed to provide a strong, vibration-resistant grip, preventing the cable gland body from loosening under mechanical stress. They are available in brass, nickel-plated brass, and stainless steel, and are compatible with metric, PG, and NPT thread sizes.
Sealing Rings and Washers
Available in EPDM, Neoprene, NBR (Nitrile), and Silicone, CabexIndia’s sealing rings create an airtight, watertight barrier between the gland body and the enclosure wall. Material selection depends on the operating temperature, chemical exposure, and IP rating required.
Earth Tag Washers and Earthing Accessories
Proper earthing is a legal safety requirement in all electrical installations. CabexIndia’s earth tag washers ensure reliable electrical continuity through the cable gland, preventing dangerous potential differences between the cable armour and the equipment enclosure.
Reducers and Adaptors
When the metric, PG, or NPT thread size of the cable gland does not match the knockout size on the enclosure, a reducer or adaptor bridges the gap. CabexIndia manufactures these in a full range of sizes and thread combinations, eliminating the need for costly custom enclosure modifications.
Blanking Plugs
Unused cable entries in enclosures must be sealed to maintain the IP rating of the installation. CabexIndia’s blanking plugs are available in brass, stainless steel, and nylon, with optional seal rings for IP65 to IP68 ratings.
Installation Best Practices for Industrial Cable Glands
Correct installation is critical to achieving the IP rating, mechanical strength, and certification compliance that industrial cable glands are designed to deliver.
- Select the correct gland size — measure the cable outer diameter (OD) accurately and select a gland whose clamping range spans the cable OD
- Clean the cable entry hole — remove burrs, debris, and corrosion from the enclosure knockout before fitting
- Use the correct sealing ring — always fit the sealing ring appropriate for the cable OD and operating environment
- Tighten to the correct torque — over-tightening can damage sealing rings; under-tightening compromises the IP rating
- Verify earthing continuity — for armoured cables, confirm that the earth tag/clamp makes good contact with the cable armour
- Apply thread sealant where required — for high-IP applications, apply appropriate thread sealant (not PTFE tape for plastic glands) to ensure a gas-tight seal
- Document and record — for ATEX installations, record gland type, batch number, and installation date for future audit compliance
Maintenance and Replacement Guidelines
Industrial cable glands require periodic inspection to maintain their protective function over the service life of the installation:
- Annual visual inspection — check for cracks, corrosion, deformation, or UV degradation of the gland body and sealing ring
- Torque verification — re-check tightening torque annually for vibration-intensive applications
- IP rating re-verification — after any cable modification or gland disturbance, re-verify the IP seal before recommissioning
- Replace on failure indicators — replace immediately if the gland body is cracked, the sealing ring is compressed flat, or the locknut cannot be tightened
- ATEX record-keeping — maintain logs of ATEX/IECEx batch numbers and installation dates for regulatory audits

Frequently Asked Questions (FAQs)
Q1. What is the difference between a cable gland and a cable connector?
The terms are often used interchangeably. “Cable gland” is the standard British/IEC terminology, while “cable connector” or “cable fitting” is sometimes used in North America. Both refer to the mechanical device that secures a cable to an enclosure.
Q2. What IP rating do I need for an outdoor industrial installation?
At minimum, IP65 for sheltered outdoor locations. For exposed, wet, or underground applications, IP67 or IP68 is recommended.
Q3. Do I need ATEX-certified cable glands for my application?
If your installation is in a classified hazardous zone (Zone 0, 1, 2, 20, 21, or 22) where an explosive atmosphere of gas or dust may be present, ATEX-certified glands are legally mandatory in the EU, and IECEx certification is required or strongly recommended in other international jurisdictions.
Q4. Can I use a brass cable gland in a stainless-steel enclosure?
Yes, but you should use a brass-to-stainless steel compatible sealing ring and ensure an earth tag washer is fitted to prevent galvanic corrosion at the contact point.
Q5. What is the difference between metric, PG, and NPT thread cable glands?
Metric (M) threads are the most widely used globally. PG (Panzer-Gewinde) is an older European standard still found in legacy enclosures. NPT (National Pipe Tapered) is the North American standard. Thread conversion adaptors — available from Cabex India — allow mixing of thread forms when required.
Q6. How do I verify that a cable gland is genuinely ATEX/IECEx certified?
Genuine certified glands carry a permanently marked certification number (e.g., Ex marking, notified body number, certificate number). Certification documents should be available from the manufacturer. Cabex India provides full certification documentation with every certified product.
