## Summary description

Pneumatic male threaded fitting PARTNER PA-MH04/04 with 1/4" external thread and a 6 mm push-in (herringbone) hose connection. Designed for compressed air systems and pneumatic installations, it joins threaded ports to 6 mm tubing. Suitable for workshops, automation equipment and general pneumatic repairs where a compact threaded-to-tube transition is needed.

## Long description

Pneumatic male threaded fitting PARTNER PA-MH04/04 with a 1/4" external thread and a 6 mm push-in "herringbone" hose connection provides a compact threaded-to-tube transition for compressed air systems. The fitting couples a standard 1/4" male thread to 6 mm polyethylene or polyurethane tubing via a push-fit barb, enabling quick assembly and a reliable seal in pneumatic installations. It is intended for workshops, automation systems and general pneumatic maintenance tasks where space-saving connectors and ease of tubing replacement are required.
Advantages
The PARTNER male threaded fitting features a straightforward push-in barb that reduces assembly time and eliminates the need for clamps in typical soft-tube applications. Its compact design allows installation in confined spaces and maintains a stable connection under normal pneumatic working pressures. The 1/4" external thread is compatible with common pneumatic ports and valves, while the 6 mm push-in interface supports quick disconnection and reconfiguration of tubing runs.
Suitable for
Connecting 1/4" threaded ports to 6 mm pneumatic tubing in compressed air circuits
Workshop equipment repairs and maintenance
Automation and control systems with small-diameter tubing
Prototyping and temporary pneumatic test setups
Key specifications
Thread type: 1/4" external (male) threaded connection
Tubing connection: 6 mm push-in "herringbone" barb for soft tubing
Application: pneumatic compressed air systems and installations
Design: compact threaded-to-tube adapter for confined spaces
Compatibility: intended for standard pneumatic ports and valves with 1/4" male thread
How to use
Ensure mating threads are clean and free of debris before installation. Hand-start the 1/4" male thread into the corresponding female port, then tighten to a suitable torque using appropriate tools to secure the connection without over-tightening. Insert the 6 mm tubing fully onto the push-in barb until it seats against the shoulder; for improved retention in higher vibration environments, use an external clamp or sleeve designed for soft pneumatic tubing. To disconnect the tubing, depress the release area on the push-in barb (if present) or cut the tubing behind the barb and re-terminate as needed.
Usage recommendations
Verify tubing material compatibility (e.g., polyethylene, polyurethane) with the push-in barb and observe system pressure limits of your pneumatic installation. Do not exceed the recommended working pressure of connected components, and inspect the joint regularly for leaks. Use thread sealant or tape on the 1/4" thread only if required by the mating port specifications, and avoid excessive torque to prevent thread damage.
