What is a metal cable gland and why is it used?

A metal cable gland is a robust entry point that seals and secures electrical cables as they pass through enclosures, panels, or equipment housings. Manufactured from materials such as stainless steel, brass, or aluminium, metal cable glands provide mechanical protection, strain relief, and environmental sealing for harsh industrial environments. They are designed to maintain electrical integrity by providing a dependable ingress protection (IP) rating, enabling armor compatibility, and often offering grounding paths. In practice, metal cable glands are used with power, control, and signal cables in machines, automation, robotics, marine, and outdoor installations. At RS Components you’ll find a broad selection of metal cable glands in metric and imperial thread formats, with or without sealing gaskets, locknuts, and accessories to meet IP66, IP68, and even ATEX/IECEx requirements for hazardous areas.

What materials are metal cable glands commonly made from, and how do I choose?

Metal cable glands come in several corrosion-resistant materials, each suited to different environments and cables:
  • Stainless steel (A2/A4 or 304/316 equivalents): Excellent corrosion resistance, ideal for harsh, wet, or coastal environments and for sanitary or food-grade applications.
  • Brass (often nickel-plated): Good mechanical strength and conductivity, suitable for indoor or general industrial use with moderate corrosion exposure.
  • Aluminium (anodised or natural): Lightweight with decent corrosion resistance; cost-effective for large-size glands or where weight matters.
  • Alloy or coated variants: Offer a balance of cost, strength, and resistance, often used in marine or chemical environments.
When choosing, consider cable type (armored vs. non-armored), operating temperature, humidity, chemical exposure, and the required IP rating. For hazardous areas, select glands with ATEX/IECEx approvals and appropriate flameproof or intrinsic safety classifications. Always check compatibility with the enclosure material to avoid galvanic corrosion.

What sizes and thread types are available for metal cable glands?

Metal cable glands are offered in a wide range of entry sizes to suit conductors from small control cables to large power feeds. Thread types commonly include:
  • Metric threads: M12, M16, M20, M25, M32, M40, M50 and up to M63, in inline or bulkhead variants.
  • Imperial/NPT threads: NPT options for regions or applications requiring standard pipe-thread formats.
  • PG threads: Traditional PG7, PG9, PG11, PG13.5 variants found in older equipment and certain installations.
Entry diameters align with cable diameters and armour needs (non-armoured, unarmoured, or braided/armoured). Gland kits may include sealing rings, gaskets, and locknuts to fit the exact thread size and mounting style. Always refer to the manufacturer datasheet for precise torque values and sealing recommendations.

How do I install a metal cable gland correctly in an enclosure?

Proper installation ensures sealing, strain relief, and long service life. Follow these general steps:
  • Choose the correct gland size, thread type, and IP rating for your cable and enclosure.
  • Prepare the seal: use the supplied gasket or O-ring appropriate for the gland and gasket material compatibility with enclosure material.
  • Drill or punch the correct knockout and clean the mounting hole to avoid gaps.
  • Insert the gland body through the enclosure until the flange or mounting shoulder sits flush.
  • Place the gasket, if required, and fit the locknut to secure the gland. For armored cables, ensure armour bonding and use a suitable sealing washer if provided.
  • Insert the cable through the sealing element, tighten the compression nut or gland nut to the recommended torque. Do not overtighten, as this can damage the gasket or fibre/armour.
  • Route and clamp the cable or armour to relieve strain and maintain horizontal alignment to reduce bending stress.
After installation, verify ingress protection by performing a basic water or leak test if applicable and ensure there are no gaps around the gland or gasket. Use compatible sealants only if recommended by the gland manufacturer.

Are metal cable glands suitable for outdoor use or hazardous locations?

Yes, metal cable glands are widely used outdoors and in hazardous locations when selected with the right ratings. Look for:
  • IP ratings: IP66, IP68, or higher for water, dust, and immersion protection in external or washdown environments.
  • Material choices: Stainless steel or coated options for superior corrosion resistance.
  • Hazardous area approvals: ATEX or IECEx certifications for explosive atmospheres (gas or dust) with flameproof or intrinsic safety classifications.
  • Environmental specifications: Temperature ranges, UV resistance, and chemical exposure tolerance.
When using outdoors or in hazardous zones, choose a gland with the appropriate approvals and install per the enclosure manufacturer’s instructions to maintain compliance and safety.

What is the difference between standard, flameproof, and explosion-proof metal cable glands?

The terminology reflects the gland’s suitability for hazardous environments:
  • Standard metal glands: Built for general industrial use with good sealing and mechanical protection; rely on IP ratings for enclosure protection.
  • Flameproof (Ex d) glands: Designed to contain an internal fault without igniting a surrounding explosive atmosphere, suitable for certain hazardous zones and equipment interiors when used with compliant housings.
  • Explosion-proof (Ex e, Ex td, Ex d) glands: Certified for use in hazardous areas with certified enclosures or equipment; depend on the combination of gland, cable, and enclosure for overall safety.
Always verify the applicable standards (ATEX/IECEx, CSA, UL) and ensure the gland selection matches the enclosure rating and the specific hazardous area classification.

What accessories accompany metal cable glands and how do I choose them?

Accessories enhance sealing, strain relief, and mounting convenience:
  • Seals and gaskets: O-rings or flat gaskets for IP sealing and gasketing compatibility with enclosure materials.
  • Locknuts: Used to secure the gland from the exterior; some designs use captive nuts or hex nuts.
  • Sealing washers: For armour or armour-terminated cables to improve bonding and sealing.
  • Compression rings and nuts: For compression-type glands that seal around the cable jacket or armour.
  • Cable clamps and strain relief: Optional accessories to reduce movement and mechanical stress on the cable entry.
When selecting accessories, ensure material and gasket compatibility with your enclosure, cable jacket, and operating environment. Always follow the gland manufacturer’s torque and assembly guidelines to maintain IP and safety ratings.

How do I determine the right gland size for my cable and armor?

Start with the outer diameter of the cable including any armour. Refer to the gland size chart or datasheet to find the closest matching entry size (for example, M20 to fit a 7–9 mm cable, M25 for 9–13 mm, etc.). If armour is present, ensure the gland is rated for armour‑clad cables and consider any required bonding to the enclosure. For large or flexible cables, select a gland with a slightly larger entry and verify that the sealing mechanism can accommodate the cable diameter without excessive compression, which could damage insulation. Always confirm with the supplier’s specifications and, when in doubt, contact technical support for a fit-for-purpose recommendation.

What standards and certifications apply to metal cable glands?

Metal cable glands commonly comply with a range of standards and certifications to ensure safety, performance, and environmental responsibility:
  • IP rating (IEC 60529): Defines ingress protection against solids and liquids.
  • Electrical safety and compatibility: CE marking for Europe; UL or CSA approvals where required.
  • RoHS: Restriction of hazardous substances compliance.
  • Hazardous area certifications: ATEX and IECEx for explosion-protected environments; Ex e, Ex d classifications as applicable.
  • Mechanical and performance standards: EN and IEC standards for mechanical strength and sealing performance.
When selecting glands for specific markets or industries, verify the exact certification scope for the gland model, enclosure, and cable combination to ensure full compliance.

How can I maintain metal cable glands for long service life?

Maintenance helps preserve sealing, corrosion resistance, and mechanical integrity:
  • Regularly inspect seals, gaskets, and O-rings for cracks or deformation; replace if damaged.
  • Check the torque on locknuts or compression fittings and re-torque if specified by the manufacturer.
  • Keep gland bodies clean and free of corrosive residues; wipe with compatible cleaners and avoid aggressive solvents that may attack seals.
  • Use compatible anti-corrosion coatings or lubricants only when recommended; avoid penetrating greases that could affect sealing performance.
  • Replace worn or damaged armour connectors and ensure the enclosure maintains its IP rating after maintenance.
Proper maintenance reduces the risk of water ingress, dust ingress, and cable movement that can degrade insulation or conductor integrity.

What are some tips for selecting metal cable glands for automation and control panels?

For automation and control panels, consider:
  • Common gland types for panels include metric M-series glands with captive nuts for easy mounting and reliable sealing.
  • Armor compatibility if using shielded or braided cables; ensure the gland supports armour bonding and termination.
  • Preferred IP ratings (IP66/IP68) to withstand washdowns and dust ingress in factory floors.
  • Availability of accessories like sealing rings, locknuts, and strain-relief options for neat cable management.
  • Mounting hardware compatibility with enclosure materials (steel, stainless steel, or polycarbonate) to avoid galvanic corrosion.
RS Components offers a broad portfolio of metal cable glands suitable for control panels, robotics, and machine building, with datasheets detailing size, thread, material, and ratings to help you make an informed choice.
