501/423 Cable Gland Details


The 501/423 cable gland provides two independent seals on non-armoured elastomer and plastic insulated cables. The first is a flameproof seal on the inner or outer cable sheath, with an additional IP seal on the outer sheath. The cable gland is dual certified Exd and Exe and is suitable for installation in Zone 1 (21) and Zone 2 (22) hazardous areas.


Provides superior cable retention to standard unarmoured cable glands, with seal at two independent points. When used in increased safety applications, this cable gland may be used with braided cable where the braid and the outer sheath pass into the enclosure. The braid must be suitably terminated inside the enclosure.
