BeskrivelseTeknisk infoSupport


Outdoor or indoor use.
For use with conduit incorporating individual insulated conductors or for particular use with:-
a) Cable inner sheaths that are not effectively filled, compact and/or circular, have tape bedding or have hygroscopic fillers.
b) Cables that exhibit 
‘cold flow’  characteristics.
c) Enclosures containing an ignition source in gas group IIC areas or containing an ignition source in a Zone 1 area.


Provides a barrier seal between the individual insulated cores within the cable and prevents entry of the products of an explosion into the cable or conduit.
Seals conductors at entry to enclosure via conduit or enables an existing cable gland to be converted to a barrier type cable gland.
The device is fitted with a simple compound filled chamber which permits packing around individual insulated conductors. Assembly of the cable gland compresses and distributes the compound evenly to create a barrier seal at the point of entry into the enclosure. The 
compound chamber  may be separated from the cured compound to ensure that the chamber has been effectively filled. If required, external voids can be repaired.
Provides female running coupler for cable gland or conduit entry.

Materials & Finishes

The CSB 656N cable gland is manufactured in Brass (standard), Nickel Plated Brass, 316 Stainless Steel or Aluminum. Brass NPT entries are nickel plated as standard.
