In hazardous industrial environments, cable glands play an important role in maintaining safe and secure cable entry into electrical enclosures. Ex d nickel-plated double compression cable glands are designed for armoured cables, providing flameproof protection, reliable sealing, mechanical cable retention, and corrosion resistance. They are commonly used in oil & gas, petrochemical, chemical, marine, and other hazardous-area applications.
What Does "Ex d" Mean?
"Ex" identifies equipment designed for explosive atmospheres, while "d" refers to flameproof protection. Ex d glands are designed to maintain the flameproof integrity of an enclosure and prevent an internal ignition from igniting the surrounding atmosphere. They are typically certified to relevant IEC 60079 standards.
Why Nickel-Plated?
Nickel-plated brass provides corrosion resistance, durability, and good electrical conductivity. This makes it suitable for oil & gas, petrochemical, marine, chemical, and other harsh industrial environments.
What Is a Double Compression Cable Gland?
A double compression cable gland is designed for armoured cables. It provides:
- Inner compression for sealing and cable retention
- Armour clamping for mechanical support and electrical continuity
- Outer compression for environmental protection against dust and moisture
Why Combine These Features?
An Ex d nickel-plated double compression cable gland combines flameproof protection, corrosion resistance, and secure sealing for armoured cables entering hazardous-area enclosures.
| Feature | What it gives you |
|---|---|
| Ex d certification | Flameproof joint, suitable for Zone 1 and Zone 2 gas areas (Group IIC) |
| Nickel plated brass | Corrosion resistance, long life, good bonding |
| Double compression | Sealing of both inner and outer sheaths, armour retention and earthing |
| Single compression | Where protection against dust and moisture is needed but where mechanical stress is not extreme |
Where Are These Glands Used?
Ex d nickel-plated double compression cable glands are commonly used in:
- Oil & gas and petrochemical facilities
- Offshore platforms and marine applications
- Chemical and pharmaceutical plants
- Fuel storage and power generation facilities
- Mining and grain-handling areas requiring dust protection
How to Choose the Right Gland
1. Check the hazardous area
Confirm the Zone, gas/dust group, and temperature class, and ensure the gland certification covers the application.
2. Check the cable type
Double compression glands are designed for armoured cables. Check the cable construction and armour type.
3. Check cable dimensions
Measure the inner bedding and overall cable diameter and select a gland with the correct sealing range.
4. Match the thread
Ensure the gland thread (Metric, NPT, BSP, etc.) matches the enclosure entry exactly.
5. Check IP rating and temperature range
Confirm the gland provides the required IP protection and can operate within the site's temperature conditions.
6. Verify certification
Check the relevant ATEX, IECEx, or applicable certification and ensure it is suitable for the intended hazardous-area application.

Common Mistakes to Avoid
- Using non-certified glands in hazardous areas.
- Selecting the wrong gland for the cable type or diameter.
- Applying sealants to flameproof threads unless permitted by the certification.
- Mixing thread types or overtightening compression nuts.
- Leaving unused entries open or using uncertified plugs.
- Ignoring temperature ratings and gas group requirements.
Maintenance and Inspection
Regularly inspect glands for corrosion, damaged seals, loose nuts, damaged threads, missing certification marks, and signs of water or dust ingress. Replace damaged glands with equivalent certified parts rather than attempting repairs.
