Summary
A double compressor gland is a critical industrial component that provides dual-seal protection for armoured and unarmoured cables in demanding environments — from oil refineries to offshore platforms, power plants, and chemical facilities. This guide covers everything a procurement engineer, electrical contractor, or site manager needs to know: what a double compressor gland is, how it works, which type to select, and why Cabex India — with over 25 years of manufacturing experience and global certifications including ATEX, IECEx, CE, and PESO — is the most trusted source to buy from. Whether you are looking to purchase a single unit or place a bulk industrial order, this guide will help you make the smartest, safest decision.
What Is a Double Compressor Gland?
A double compressor gland — also widely referred to as a double compression cable gland — is a precision-engineered mechanical fitting used to terminate and seal cables at entry points to electrical enclosures, junction boxes, control panels, and machinery. Unlike its single-compression counterpart, a double compressor gland creates two independent sealing points:
- Seal 1 — Inner sheath seal: Grips tightly around the cable’s inner insulation layer, preventing moisture or gas from travelling along the cable core.
- Seal 2 — Outer sheath seal: Compresses around the cable’s outer sheath, blocking environmental ingress from the entry point.
This dual-seal architecture is what gives double compressor glands their hallmark advantages: superior IP66/IP68 weatherproof protection, outstanding mechanical cable retention, reliable earth continuity through armour termination, and the ability to meet stringent international safety standards for hazardous areas.
If you are specifying cable terminations for any outdoor, industrial, or hazardous environment — a double compressor gland is not optional. It is essential.

Double Compressor Gland vs Single Compression Gland: Key Differences
Understanding the core difference between these two gland types is essential for safe and compliant cable management. The table below breaks it down clearly:
| Feature | Single Compression Gland | Double Compressor Gland |
|---|---|---|
| Number of Sealing Points | 1 (outer sheath only) | 2 (inner + outer sheath) |
| Cable Type Compatibility | Unarmoured cables | Armoured (SWA, AWA, STA) & unarmoured |
| IP Rating | IP54 to IP66 | IP66 to IP68 |
| Environmental Suitability | Dry/indoor environments | Outdoor, hazardous, corrosive environments |
| Armour Clamping | No | Yes — mechanical earth continuity |
| ATEX/IECEx Suitability | Limited | Yes — Zone 1, Zone 2, Zone 21, Zone 22 |
| Cost | Lower | Moderate (superior value for harsh use) |
| Typical Applications | Control panels, indoor MCCs | Oil & gas, power, marine, petrochemical |
Conclusion: Whenever your cable is armoured, outdoors, or installed in a hazardous location, a double compressor gland from Cabex India is the only correct and safe choice.

How to Select the Right Double Compressor Gland: A Step-by-Step Guide
Choosing the wrong gland can result in IP rating failure, earth continuity faults, and dangerous non-compliance. Follow this proven selection process used by professional electrical engineers:
Step 1 — Determine Cable Type Is your cable armoured (SWA, AWA, STA) or unarmoured? Armoured cables always require a double compressor gland to achieve earth continuity through the armour layer.
Step 2 — Measure Cable Outer Diameter (OD) Measure the overall outer diameter of your cable accurately. The gland’s clamping range must comfortably accommodate your cable OD — never force a gland onto an undersized or oversized cable.
Step 3 — Identify the Entry Thread Match the gland’s entry thread to your enclosure’s thread form — metric (M20, M25, M32, etc.), NPT (1/2″, 3/4″, 1″), or PG. Using the wrong thread form compromises the IP seal at the enclosure interface.
Step 4 — Specify the Environment Is the installation outdoor, underground, in a chemically corrosive atmosphere, or in a hazardous area? This determines whether you need weatherproof, explosion-proof, or flameproof certification.
Step 5 — Select Material Brass for general industrial use. Nickel-plated brass for enhanced corrosion resistance. Stainless steel for marine, offshore, pharmaceutical, or highly corrosive environments.
Step 6 — Verify Certifications For hazardous areas: confirm ATEX/IECEx certification and the applicable zone rating (Zone 1, 2, 21, or 22). For global export projects, confirm CE and country-specific compliance.

How to Install a Double Compressor Gland: Best Practices
Correct installation is just as important as correct selection. Poor installation is one of the most common causes of IP rating failure in the field.
- Verify the gland size matches your cable’s outer diameter before beginning.
- Strip the outer sheath carefully, exposing the correct length of armour as specified in the gland’s installation sheet.
- Cut and fold back the armour wires neatly so they make full, even contact with the gland body’s armour clamping cone.
- Assemble the gland components in the correct order: locknut → washer → sealing ring → armour clamp → gland body.
- Hand-tighten the back nut first, then use an appropriate spanner. Do not overtighten — excessive torque can damage the cable sheath and compromise the seal.
- Fit a sealing washer at the enclosure interface to maintain the IP rating between the gland and the panel.
- Apply a PVC shroud in highly corrosive or outdoor environments for added long-term protection.
- Test earth continuity between the cable armour and the enclosure body post-installation.

Frequently Asked Questions (FAQs) — Double Compressor Gland
Q1. What is a double compressor gland? A double compressor gland is a precision mechanical fitting that creates two sealing points on a cable — one on the inner sheath and one on the outer sheath. This dual-seal design provides superior IP66/IP68-rated weatherproof protection and is essential for armoured cable installations in industrial and hazardous environments.
Q2. What is the difference between a double compressor gland and a single compression gland? A single compression gland has only one sealing point (on the outer sheath) and is suited to unarmoured cables in dry indoor locations. A double compressor gland has two sealing points, accommodates armoured cables, and is rated up to IP68 — making it the correct choice for outdoor, hazardous, and corrosive environments.
Q3. Which industries use double compressor glands? Double compressor glands are used extensively in oil and gas, petrochemicals, power generation, mining, marine, offshore, infrastructure, pharmaceutical, and industrial automation sectors — anywhere armoured cables are terminated in demanding environments.
