Cable entry · Retention, sealing and metal compatibility
A cable gland has to hold the cable, seal the entry and, for armoured cable, carry fault current to earth. CMP says that for a non-standard armour such as aluminium wire armour "it may be necessary to consider an alternative Cable Gland material, e.g. Aluminium" [[cmp]]; the choice only works if the gland's retention, sealing and earth path are proven for your cable and the metals in contact are compatible.
Metal cable glands for industrial electrical installations, including aluminium, brass and stainless steel, for unarmoured, braided and armoured cables. Hazardous-area glands need additional certification and are only touched on here.

IEC 62444 sets requirements and tests for the construction and performance of complete cable glands as supplied, for IEC 60423 metric entry threads (and as a guide for other threads); it excludes glands for mineral-insulated cables. It defines a cable gland as a device for the entry of a cable into an enclosure that provides sealing and retention, and may also provide earthing, bonding, insulation, guarding or strain relief. [1]
The standard's contents cover classification, cable retention tests with pull forces, resistance to impact, equipotential bonding to the equipment and to the cable's metallic layers with an electrical current test, and degree of protection to IEC 60529. Ask the supplier which retention, impact and current classes and which IP code each gland has been tested to, and by whom. [1]
For hazardous areas the standard notes that additional requirements, for example in the IEC 60079 series, apply. [1]
Give the supplier the cable type and outer diameter, inner sheath diameter for armoured cable, armour type and material, entry thread and enclosure material, IP rating to maintain and any hazardous-area or deluge requirement.
02
Match gland metal to the armour and the enclosure
CMP Products, a cable gland manufacturer, advises checking the type and material of the cable armour and its short-circuit fault current rating, and notes that for non-standard armour such as aluminium wire armour an alternative gland material, for example aluminium, may need to be considered. [2]
CMP also advises checking the enclosure material to eliminate dissimilar metals where possible, whether plating such as nickel is required, the corrosion environment and the gland-plate thickness, which may call for a longer thread. [2]
Ask the supplier for the aluminium alloy and any plating or anodising, the corrosion test applied, and whether earth tags and locknuts are rated for the armour fault current.
03
Keep the IP rating of the enclosure
CMP lists the IP rating of the equipment or site standard to be maintained, whether a single or double seal gland is needed, whether an entry-thread sealing washer is needed to achieve the IP rating, any deluge protection, and stopper plugs for unused entries. [2]
It warns that sealing performance of washers and short-circuit rating of earth tags and grounding locknuts cannot be guaranteed when accessories from other sources are used. Buy glands and accessories as a matched set and keep the test certificate with the installation record. [2]
04
Metal, brass and nylon glands in the linked listings, and what they do not state about aluminium
Cagland, CHS and Degson list metal, brass and nylon cable glands for industrial enclosures. [3][4][5]
Cagland describes itself as a metal cable gland maker; CHS lists nylon and brass cable glands with wiring duct; Degson lists cable glands with its terminal blocks. None of the supplier pages reviewed states an aluminium gland range, so ask each for aluminium availability and test certificates. [3][4][5]

Buyer questions
When should I use an aluminium cable gland?
CMP notes that for non-standard armour such as aluminium wire armour, an alternative gland material such as aluminium may be needed, and advises avoiding dissimilar metals with the enclosure where possible. [2]
What does IEC 62444 cover?
Requirements and tests for complete cable glands with metric entry threads, including retention, impact, bonding and current tests and IP to IEC 60529; it excludes glands for mineral-insulated cable. [1]
Can I mix accessories from other makers?
CMP warns that sealing and short-circuit performance cannot be guaranteed when washers, earth tags or locknuts from other sources are used. [2]
Sources and what still needs a direct check
Sources checked 2026-10-10. IEC 62444 was read from the publisher's preview (scope, definition and contents). CMP Products is a cable gland manufacturer. Supplier pages describe their own offers. IEC 60529, IEC 60423 and the IEC 60079 series were not read for this page.
