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.

China SFC20-1SCH252N-SFC20-1SFG092N Manufacturer, Supplier

The SFC Series Ball Valve Quick Connector is a premium, full-flow fluid connection solution designed for high-demand liquid cooling and fluid transfer systems. Manufactured by Hoonsun, this connector features a 304 stainless steel body and precision ball valve mechanism, delivering superior sealing, low pressure drop, and long-term reliability.

Available in DN20, DN32, and DN40 sizes, it supports a rated working pressure of 16 bar (burst pressure 64 bar) and operates reliably across a wide temperature range of -40°C to +120°C. The standard EPDM seal (with optional FKM/NBR variants) ensures compatibility with deionized water, glycol solutions, and common industrial fluids. The plug-and-play design, combined with multiple connection options (female thread, hose barb, tri-clamp), enables fast, leak-proof installation in critical systems.

🔧 Installation Process

1. Preparation

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

2. Connection

Align the connector with the mating socket, then push until a secure lock is achieved. The ball valve will automatically open upon full engagement.

3. Verification

Perform a pressure test to confirm no leaks before bringing the system online.

4. Disconnection

Depressurize the system, then simply pull the connector out of the socket. The ball valve will automatically close to prevent fluid loss.

⚠️ Safety Note: Never connect or disconnect the coupling while the system is under pressure. Protect the sealing surface from scratches to maintain leak-proof performance.
