What does IP68 mean for a cable gland?

IP68 under IEC 60529 means the gland is dust-tight (6) and protected against continuous immersion in water (8) under conditions agreed between manufacturer and user. The rating is only valid when the cable outer diameter sits inside the gland's stated clamping range and the cap nut is tightened to the recommended torque.

Should I choose a metal or nylon cable gland?

Nylon PA66 glands are lightweight, corrosion-free and cost-effective for control cabinets, lighting and general outdoor equipment. Nickel-plated brass or stainless steel glands are preferred where you need mechanical strength, EMC shielding, higher vibration resistance, fire performance or exposure to oils, salt spray and UV.

Which thread standards do HOONSUN cable glands support?

HOONSUN supplies cable glands in Metric (M), PG, NPT and G (BSPP) threads. Thread length can be specified to match enclosure wall thickness, and custom thread forms are available for OEM projects.

Can HOONSUN produce custom or OEM cable glands?

Yes. As an in-house manufacturer since 2006, HOONSUN customizes thread type, thread length, seal material, clamping range, plating, colour and private-label packaging for OEM and distributor programs.

What certifications do HOONSUN cable glands carry?

Standard HOONSUN cable gland ranges are produced to CE and UL requirements with IP68 sealing performance. Test reports and certificate copies are supplied with the product catalog or on request for each specific part number.

Frequently Asked Questions

Q What does IP68 certification mean for this product?

IP68 is the highest ingress protection rating, meaning the product is fully protected against dust ingress and can withstand continuous immersion in water beyond 1 meter. This ensures reliable performance even in wet or submerged environments.

Q Why is stainless steel used as the main material?

Stainless steel provides exceptional corrosion resistance, mechanical strength, and durability. It is ideal for harsh environments including marine, chemical, and outdoor applications where long-term performance is critical.

Q How does the breather membrane work?

The specialized breather membrane allows air to pass through while blocking water and dust. This equalizes pressure differences caused by temperature changes inside sealed enclosures, preventing condensation and potential damage to internal components.

Q Is this product suitable for marine and offshore use?

Yes. Thanks to its stainless steel construction, IP68 rating, and robust design, this product is well-suited for marine and offshore applications where exposure to saltwater, humidity, and extreme conditions is common.

Q How easy is the installation process?

The product features a compact, threaded design that allows for straightforward installation without specialized tools. It can be easily mounted into standard threaded ports on enclosures, control boxes, or equipment housings.

Q Does UL recognition affect product quality or safety standards?

UL (Underwriters Laboratories) recognition confirms that the product has been tested and meets established safety and performance standards. This provides assurance of quality and reliability for use in electrical and industrial applications.
