Shut-off nozzle for quick coupling 'herringbone' 8 mm brass by PARTNER PA-BSE2-3PH

Brass shut-off nozzle for quick coupling with an 8 mm herringbone (barb) connection designed for secure hose attachment in pneumatic and fluid systems. Manufactured by PARTNER, this brass valve element integrates with quick coupling assemblies to enable controlled isolation of a hose line without disconnecting the entire coupling. The compact brass construction offers dimensional stability and compatibility with standard 8 mm barb hoses used in workshop, maintenance and industrial environments.

Advantages

The brass shut-off nozzle provides reliable sealing and resistance to corrosion typical for brass fittings, ensuring longer service life in wet or oily conditions. The 8 mm herringbone barb gives a positive mechanical grip to flexible hoses, reducing the risk of slippage when secured with a clamp. Designed for quick coupling systems, the nozzle allows rapid installation and straightforward replacement during repairs or assembly work.

Suitable for

• Pneumatic lines and compressed air distribution where an 8 mm barb connection is used
• Fluid transfer systems with flexible hoses requiring a shut-off function
• Workshop repairs, maintenance tasks and equipment assembly
• Industrial applications where compact, corrosion-resistant hose fittings are needed

Key specifications

• Material: brass for corrosion resistance and mechanical durability
• Connection type: 8 mm herringbone (barb) hose connection
• Function: integrated shut-off valve for isolating flow at the coupling
• Compatibility: designed to work with standard quick coupling assemblies and flexible hoses sized for 8 mm barb fittings
• Design: compact form factor suitable for tight installation spaces

How to use

Insert the 8 mm herringbone barb securely into the flexible hose and fasten with an appropriate hose clamp to ensure a leak-free mechanical connection. Install the nozzle into the mating quick coupling assembly following the coupling manufacturer’s instructions for seating and locking. Operate the shut-off function by actuating the nozzle or coupling mechanism to isolate the line before disconnection or maintenance. Inspect the connection for leaks after pressurizing the system and retighten the clamp if necessary.

Usage recommendations

Use hose clamps rated for the application pressure and temperature, verify material compatibility of fluids with brass, and perform periodic inspections for wear or corrosion. When working with compressed air or hazardous fluids, depressurize the line and follow safety procedures before disconnecting or servicing the nozzle.
