Norgren 102250405 Straight Adapter Fitting M5x0.8 4mm

Product Description

The NORGREN 102250405 is a push-to-connect straight adapter fitting designed to join a 4mm outside diameter tube to an M5 x 0.8 metric thread port. Constructed from nickel-plated brass, this fitting delivers corrosion resistance and reliable sealing in pneumatic and fluid control systems. It is rated to 260 psi maximum working pressure and operates across a temperature range of 0 degrees F to 175 degrees F. The nitrile O-ring provides a secure, leak-free connection at the tube interface. At 20mm overall length, this compact adapter suits tight plumbing layouts. HVAC technicians, plumbers, and pneumatic systems technicians install this fitting in both residential and light commercial applications.

This straight adapter fitting is suited for pneumatic tubing runs that terminate at metric-threaded ports on valves, manifolds, solenoids, and actuators. The push-to-connect tube end accepts 4mm OD tubing without tools, while the M5 x 0.8 male thread end threads directly into a corresponding female port. It is a practical solution in compressed air distribution, instrumentation lines, and low-pressure fluid control circuits where quick, reliable connections are required.

Key Features

• Push-to-connect tube end accepts 4mm outside diameter tubing without tools
• M5 x 0.8 metric male thread for direct port installation
• Nickel-plated brass body resists corrosion in pneumatic and fluid environments
• Rated to 260 psi maximum working pressure
• Nitrile O-ring provides a reliable seal at the tube interface
• Compact 20mm overall length suits space-constrained installations

Compatibility

Designed as an OEM-style straight adapter for pneumatic and fluid control systems using 4mm outside diameter push-to-connect tubing and M5 x 0.8 metric threaded ports.

Installation Notes

Installation is performed by pneumatic system technicians or licensed plumbers working on low-pressure compressed air or fluid lines. Shut off and depressurize the system fully before removing or installing any fittings. Insert the 4mm tube firmly until it seats to ensure the collet engages; use the fitting release collar to disconnect. Thread the M5 x 0.8 end into the port by hand before applying a wrench to avoid cross-threading.
