Connector fitting PARTNER PA-BSE2-3PM external thread 3/8" brass quick coupling

PARTNER PA-BSE2-3PM is a brass connector fitting with an external 3/8" thread designed for use with quick couplings. Constructed from brass, this adapter provides a reliable threaded connection between hoses, pneumatic tools and system components. It is intended for workshop and compressed-air environments where a 3/8" external threaded coupling point is required, delivering corrosion resistance and mechanical strength typical of brass fittings.

Advantages

The brass construction ensures good resistance to corrosion and long service life under normal workshop and pneumatic conditions. The external 3/8" thread enables a standardised mating with quick couplings and threaded ports, simplifying installation and replacement. The part is compact and mechanically robust, offering leak-resistant performance when assembled correctly with appropriate sealing materials.

Suitable for

• Connecting pneumatic hoses to quick couplings
• Adapting tools and accessories to 3/8" threaded ports
• Workshop air supply lines and compressed-air distribution
• General-purpose pneumatic systems and maintenance tasks

Key specifications

• Material: brass
• Thread type: external 3/8"
• Compatibility: designed for use with quick couplings and standard 3/8" threaded pneumatic ports
• Application: pneumatic systems, workshop air tools and hose connections
• Design: compact threaded adapter for secure mechanical connection

How to use

Ensure mating threads are clean and undamaged before assembly. Apply an appropriate thread sealant or PTFE tape to the external thread if required by the system to prevent leaks. Screw the fitting into the corresponding 3/8" female port or coupling until hand-tight, then use a suitable wrench to secure the connection without over-tightening. After installation, connect the quick coupling or hose and pressurise the system gradually while checking for leaks at the joint.

Usage recommendations

Use the fitting within the working pressure and temperature limits of your pneumatic system. Match the brass fitting with compatible materials to avoid galvanic corrosion in mixed-metal assemblies. Periodically inspect threaded joints and seals for wear or leakage and replace the fitting if deformation or significant corrosion is observed.
