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.

The UQDB Series Blind-Mate Quick Connector is a precision-engineered fluid connection solution, purpose-built for automated, high-density liquid cooling systems. Manufactured by Hoonsun, this blind-mate coupling features a 316L stainless steel body and advanced sealing technology, enabling reliable, tool-free connections in blind-mating environments.

Available in DN03, DN05, DN07, and DN10 sizes, it supports a rated working pressure of 20 bar (burst pressure 80 bar) and operates across a wide temperature range of -40°C to +120°C. The EPDM seal ensures compatibility with deionized water, glycol solutions, and common industrial fluids. The self-aligning design allows for fast, error-proof connections without visual alignment, making it ideal for high-volume, automated assembly processes.

Installation Process

1. Preparation: Ensure the connector and mating components are clean, free of debris, and undamaged. Depressurize the fluid system before installation.

2. Blind-Mate Connection: The self-aligning design automatically guides the plug into the socket as the components are brought together. No visual alignment or manual manipulation is required.

3. Verification: Once the components are fully mated, the connector will lock into place. Perform a pressure test to confirm no leaks before bringing the system online.

4. Disconnection: Simply separate the components; the connector will automatically disengage and seal to prevent fluid loss. No tools are required.

⚠️ Safety Note: Never force the connection. The self-aligning design should guide the plug into the socket smoothly. Always depressurize the system before disconnection.
