Installing Hawke cable glands correctly is essential to ensure the integrity, safety, and performance and cable termination of your LV MV HV electrical systems—especially in hazardous environments like oil & gas, petrochemical and industrial sectors.
In this guide, we’ll walk you through the correct method for installing Hawke cable glands, share common mistakes to avoid, and explain why proper installation matters.
1. Select the Right Cable Gland
Identify the cable type and choose the correct Hawke gland suited to both your cable and application. For example:
501/453/Universal – for unarmoured cable
501/453/RAC – for armoured cable
Confirm compatibility with:
Cable diameter
Armour type (SWA, braid, tape, etc.)
Zone rating (Zone 1, Zone 2)
2. Prepare the Cable
Strip the cable sheath as specified
Ensure no damage to internal conductors or armour
Trim and shape armour to fit cleanly inside the gland
3. Assemble the Hawke Cable Gland
Follow Hawke’s installation sequence precisely. Key components include:
Entry item
Inner and outer seals
Armour cone and clamping ring (for armoured cables)
Compression nut
Install in the correct order and apply any IP sealing washers where required.
4. Tighten & Secure
Use two spanners:
One to hold the gland body
One to tighten the compression nut to the recommended torque
This ensures:
Proper grip on the cable
Correct compression of sealing elements
Safe electrical continuity and strain relief
The cable gland is permanently marked with various lines/numbers indicating the correct tightening level related to the cable diameter. Following the relevant cable gland Installation Instructions, the back seal should be tightened until a seal is formed on the cable outer sheath and then tightened one further turn
5. Final Cable Gland Checks
Confirm ingress protection (IP rating)
Check earth continuity for armoured installations
Inspect for visible damage or loose components
❌ Using the wrong gland type for the cable
❌ Over-tightening or under-tightening
❌ Incorrect sequence of gland components
❌ Poor cable preparation or incorrect stripping of cable
❌ Forgetting to earth the armour

GORE-TEX PYRAD | Arc Flash Clothing
Thorne & Derrick | Arc Flash Protection Clothing Distributed from Stock | Approved Supplier | UK & Export Sales
GORTEX PYRAD
When two industry giants unite, extraordinary things happen. When that union is centred around human safety, lives are saved. ProGARM and the GORE-TEX Brand have recently launched a new range of next-generation arc-rated GORE-TEX PYRAD® stretch product technology workwear, marking a new era of innovation in protective garments.
Arc flash and fire resistance garment specialists ProGARM have teamed up with fabric pioneers at W.L Gore & Associates to develop a ground-breaking waterproof and arc-rated GORE-TEX product range. Guided by the principle of ‘safety through comfort,’ this new collection is designed to provide unparalleled protection while ensuring exceptional wearability. This collaboration is focused on delivering the most advanced protective features for workers who rely on high-performance personal protective equipment (PPE) to stay safe on the job.
Thorne & Derrick together with ProGARM are now able to offer the GORTEX PYRAD range of arc flash clothing delivering the ultimate arc flash protection with a wide range of men’s and women’s garments available in hi – vis yellow, hi-vis orange, two-tone yellow, blue and single colour blue.
Building On A Common Commitment To Safety & Quality
This professional partnership arose from the necessity to reinvent personal protective equipment (PPE) for employees who risk their lives on a daily basis while doing their vital tasks. With decades of expertise in innovative manufacturing and design techniques to deliver safe, compliant and wearable arc flash rated garments, ProGARM is leading the way in delivering fresh thinking in garment technology.
The GORE-TEX Brand, known for its fabrics and technologies that deliver long-lasting functionality and high quality, is the perfect partner, bringing its understanding of fabric technology and industry compliance to be part of something revolutionary.
This partnership is a seamless continuation of the established relationship between the two brands, following the signing of the licensee agreement in 2022. ProGARM is one of only three licensed PPE partners in the UK to utilise Gore’s cutting-edge PYRAD® technology. This highly sought-after collaboration provides a solid foundation of excellence for the companies to build upon with the introduction of their new and innovative product range.
Breakthroughs, Not Just Enhancements
The PPE industry has experienced continuous product evolution, with gradual improvements made to enhance various aspects of arc flash and fire-resistant clothing. Both ProGARM and the GORE-TEX Brand are recognised for their technical expertise, clearly showcasing their deep understanding of garment composition and fabric design to create clothing that delivers outstanding levels of protection.
But now is the time to raise the bar yet again for arc flash safety wear.
The ProGARM x GORE-TEX Brand collaboration is bringing to market a new, exclusive set of waterproof workwear products and it’s thanks to the power of stretch. Understanding the struggles of workwear that doesn’t move with its wearer, this new arc rated GORE-TEX PYRAD® stretch product technology is changing the game.
Not only are the garments technically compliant with all required regulations for arc flash risk environments, but they are super lightweight, breathable and stretchy, even when wet, offering the ultimate combination of protection and comfort in all weathers and environments. The fabric composition is unique, placing stretch technology at the heart of the design for increased wearability with no compromise on arc rated protection.
Triple Layer Protection
Introducing triple-layer technology to the market, the fabric in the new garments offers heat, flame, and arc flash protection by blocking heat flow and preventing flame propagation, thereby stopping heat from reaching the wearer’s skin. The new range of jackets, trousers, and coveralls will soon provide workers with the most advanced workwear, delivering unmatched levels of movement, flexibility, and comfort.
Known for designing garments for a range of body shapes and sizes to achieve the best possible fit, ProGARM has brought its extensive knowledge of designing for real bodies to ensure its new range is accessible to all.
The new range will be available in high visibility yellow and navy, and orange to ensure worker visibility is not compromised when on-site, and every aspect of the design is arc flash and flame resistant, right down to the stitching thread for total performance reassurance. Advanced porous technology means the fabric is breathable, working with the overall design of the range to avoid a build-up of heat and perspiration in all weather conditions. This range is designed to be worn, with every design decision made in the boots of the wearer.
With this innovative range of workwear embedded in science, there are GORE-TEX garments to suit the needs of every industry where protection from the devastating risks of an arc flash incident is a priority.
