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?

A IP68 is the highest level of ingress protection rating, meaning the product is fully protected against dust ingress and can withstand continuous immersion in water beyond 1 meter depth. This ensures reliable performance in the most demanding wet and dusty environments.

Q Why is a breather membrane necessary for sealed enclosures?

A Sealed enclosures are subject to internal pressure fluctuations caused by temperature changes. Without pressure equalization, this can stress seals and gaskets, leading to failure. The breather membrane allows air to pass while blocking moisture and dust, maintaining pressure balance and preventing condensation buildup inside the enclosure.

Q Is this product suitable for marine and offshore environments?

A Yes. The product is constructed from high-quality stainless steel specifically chosen for its superior corrosion resistance, making it well suited for marine and offshore applications where exposure to saltwater, humidity, and harsh weather conditions is common.

Q Does UL recognition indicate the product meets safety standards?

A Yes. UL (Underwriters Laboratories) recognition means the product has been independently tested and evaluated against established safety standards. This provides assurance of the product's reliability, quality, and compliance for use in safety-critical electrical applications.

Q How does this product help reduce equipment maintenance costs?

A By effectively protecting sensitive components from moisture, dust, and contaminants while preventing harmful pressure buildup, this product significantly reduces the risk of component failure and corrosion. This translates directly to lower maintenance frequency, fewer replacement parts, and an extended overall service life for your equipment.

Q What types of equipment can this product be installed on?

A Thanks to its compact, threaded design, this product can be easily installed on a wide range of equipment including electrical enclosures, control boxes, outdoor lighting fixtures, telecommunications equipment, industrial machinery, automation systems, and any other sealed systems that require pressure balance and contaminant protection.
