Hawke 501/423 Cable Glands

Hazardous Area Cable Glands from Hawke

Hawke 501/423 cable glands provide two independent seals on non-armoured elastomer and plastic insulated cables – the first of which is a flameproof seal on the inner or outer cable sheath, with an additional IP seal on the outer sheath.

Hawke 501/423 cable glands are dual certified Exd and Exe and suitable for installation in Zone 1 (21) and Zone 2 (22) hazardous areas, 3.2-91.6mm outside cable diameters.

When used in increased safety applications the Hawke cable gland can be used to terminate braided cables where the braid and the cable outer sheath enter into the electrical enclosure or junction box.

Preparing Cable & Gland For Installing Hawke 501/423
Hawke 501/423 Cable & Gland Preparation

Hawke 501/423 Cable & Gland Preparation

Cable Preparation

Allow sufficient length of cable, II, to suit equipment. If required, fit shroud. Pass cable through cable gland as shown above. Note : If the equipment has a threaded entry, it may be advisable to screw the cable gland into the equipment to prevent twisting of the cable after Step B & C.

Cable Gland Preparation

Unless already screwed into the equipment hold the entry (3) in position with a spanner/wrench to prevent rotation and tighten the middle nut (2) using a wrench/spanner until resistance is felt between the seal and cable. Then turn the middle nut through a further half to one full turn to complete the inner seal
