HEX E1W Double-Seal Brass Cable Glands – IP66 Inner & Outer Sheath Seal for SWA Cable

HEX E1W cable glands are for all types of steel-wire-armoured (SWA) cables with extruded bedding, where the gland must produce an IP66 seal on the outer sheath and also seal the inner sheath — an IP66 or explosion-proof seal. With displacement seals on both sheaths and a 2-part armour/earth lock whose knurled clamp forms a low-resistance earth clip, it is the gland for demanding sites. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

• BW — indoor, dry conditions; grips and earths the armour (IP3X).
• CW — indoor and outdoor; adds a seal on the outer sheath (IP66).
• E1W (this page) — seals both the inner and outer sheath (IP66), for SWA cables where the inner seal matters.

Frequently asked questions

What is the difference between an E1W and a CW gland?

Both seal the outer sheath to IP66; the E1W also seals the inner sheath (bedding) of extruded-bedding SWA cables.

Is the E1W an explosion-proof gland?

The E1W provides an IP66 or explosion-proof seal on the inner sheath; for certified hazardous-area use HEX makes the flameproof HE1FW, which is ATEX tested.

How is the armour earthed?

By a 2-part armour/earth lock whose knurled clamp produces a low-resistance earth clip; a cast integral earth lug (CIEL) is optional.

Which size for my cable?

Choose by diameter under armour and overall diameter — for example 4-core 50 mm² SWA usually needs size 40S. Send us the cable details to confirm.
