We'd like to keep in touch
We have some exciting things in the pipeline - if you'd like to be the first to know please enter your email address below.
Globally Approved, Explosive Atmosphere Cable Gland
• Metal-to-metal armour clamping
• Direct & remote installation
• Displacement type flameproof inner seal
• Controlled outer ‘load retention’ seal
• Unique OSTG prevents overtightening
• Designed to prevent Coldflow, see CMP Technical Document TS001 (available upon request)
• -60°C to +130°C
• Globally marked, IECEx, ATEX & cCSAus
• Superior EMC performance
Note: † Grooved Cone (X) is predominantly used for Wire Braid (e.g. GSWB, TCWB), Steel Tape Armour (STA, DSTA) and Aluminium Strip Armour (ASA) but is also suitable for Single Wire Armour (SWA), Aluminium Wire Armour (AWA) and Pliable Wire Armour (PWA) if the range is outside that of the Stepped Cone (W). Note: Grooved Cone (X) dimensions shown in the Cable Gland Selection Table below are for a double wire strand of braid armour cables. Tapes can also be doubled over. For cables that have only a single layer of armour such as SWA the clamping range should be used as shown in the table below. Stepped (W) Cone is suitable for Single Wire Armour (SWA), or Aluminium Wire Armour (AWA) cables. For under / oversized armour wires click here

Restricted Breathing (Ex nR) Equipment
Usually Ex n equipment contains components that are either non–sparking or energy limited such that ignition can be prevented when gas or vapours enter the enclosure. Restricted breathing enclosures type ‘nR’ ensure that the flammable mixture is kept away from any hot surfaces and any ignition capable components. The features of a typical Ex nR enclosure would often include:
