Cable Gland Selection Guide

Cable Gland Selection Guide: Getting It Right the First Time

A cable gland looks like a small, unglamorous component — but choosing the wrong
one is one of the most common causes of cable failure, water ingress, and even fire
risk in industrial panels. Here’s what actually matters when selecting one.

Quick answer: Choose a cable gland based on four factors — cable outer diameter, IP (ingress protection) rating required, environment (indoor, outdoor, hazardous/explosive), and cable armour type (armoured vs unarmoured).

Why Cable Glands Matter More Than They Look

A cable gland’s job is to seal the entry point where a cable passes into an enclosure —
a panel, junction box, or motor terminal. Get it wrong and you get moisture ingress,
dust contamination, mechanical strain on cable joints, and in the worst case, a fire or
explosion hazard in industrial settings.

Common Types of Cable Glands

• Single Compression Glands — for unarmoured cables in general indoor use.
• Double Compression Glands — provide two-point sealing and strain relief, standard for armoured cables in industrial and outdoor installations.
• Weatherproof (IP66/IP68) Glands — for outdoor panels, rooftop installations, and areas exposed to rain or washdown.
• Flameproof / Explosion-Proof Glands — mandatory for hazardous areas such as oil & gas, chemical plants, and pharma facilities, certified to IECEx or ATEX standards.
• EMC (Shielded) Glands — used where electromagnetic interference must be controlled, common in instrumentation and control panels.

How to Select the Right Cable Gland

• Measure the cable’s outer diameter — glands are sized to a specific range; too loose and the seal fails, too tight and it damages the cable.
• Check the entry thread size matches your enclosure (metric, PG, or NPT threads are common).
• Match the IP rating to the environment — IP66 for dust and heavy rain exposure, IP68 for submersion risk.
• Confirm armoured vs unarmoured compatibility — armoured cable glands have an extra component to clamp the steel or aluminium armour.
• Check material — brass (most common, good conductivity), nylon (costeffective, non-metallic areas), or stainless steel (corrosive/marine environments).

A Small Component, A Big Compliance Issue

For panel builders and EPC contractors, using uncertified or mismatched glands is
a common reason panels fail inspection. Sourcing from an authorized distributor
ensures certification documentation is available when your client or auditor asks for
it.

FAQs

•  It means the gland is dust-tight and protected against powerful water jets from any direction — suitable for most outdoor industrial panels.

•  Yes — armoured cable requires a double compression gland that separately clamps the inner cable and the outer armour for proper earthing and strain relief.

• Brass offersbetter mechanical strength, conductivity, and is preferred for industrial/earthed applications; nylon is lighter and used where corrosion resistance or non-conductivity is needed.
