Is the kit really IP68 waterproof?

Yes. When tightened to 3 Nm the gland passes IP68 (5-bar, 30 min) water-pressure tests.

Does it carry an official UL listing?

All PA66 parts meet UL-94 V-2 flammability and the assembly is UL-listed for conduit fittings.

What cable diameter range is supported?

¼″ (4-8 mm), ⅜″ (5-10 mm), ½″ (6-12 mm), ¾″ (10-18 mm) and 1″ (17-24 mm).

Can I reuse the glands?

Yes—nylon threads and EPDM seals allow 3-4 re-installs without degrading the waterproof rating.

Outdoor UV resistance?

UV-stabilised PA66 keeps tensile strength >70 % after 1000 h xenon-arc exposure.

FAQ

Are NPT and PG cable glands interchangeable?
No. NPT and PG use different thread standards. Match the gland to the enclosure thread and confirm the cable outside diameter before ordering.

How should I choose the correct size?
Check both the enclosure thread opening and the cable outside diameter. The gland clamping range must cover the cable diameter.

When should I choose nickel-plated brass?
Choose a brass variant when the project needs a metal gland body with durable strain relief. Confirm the NPT thread, cable clamping range, and pack quantity shown in the selected variant.

Is the 3/8-inch 50-Pack a mixed kit?
No. The 3/8-inch 50-Pack contains one NPT thread size in either black or grey. Variants labeled KIT BOX are mixed-size assortments.

Before Ordering

Confirm thread size, cable diameter range, material, color, pack quantity, and enclosure requirements before selecting a variant. Contact MAKERELE for bulk pricing or project sourcing.
