Why choose it

The zinc-nickel plating provides high corrosion resistance, ensuring long service life even in demanding environments. The self-sealing valve prevents fluid loss and contamination when the test hose is disconnected.

Ideal use cases

• Pressure monitoring in hydraulic power units
• Venting air from hydraulic systems
• Taking fluid samples for analysis
• Connecting pressure gauges or sensors

Good to know

The coupling is designed for screw-in mounting and is compatible with Stauff Test 20 test hoses and adapters. Its compact design allows installation in tight spaces.
