The NORGREN C01880418 is a push-to-connect tube-to-male BSPT tube fitting designed for general-purpose pneumatic and fluid line connections. Constructed from brass, it accepts a 4 mm outside-diameter tube on each end and connects to a male BSPT threaded port. The fitting is rated to 150 psi maximum working pressure and handles temperatures from 0 degrees F to 175 degrees F. A nitrile O-ring provides a reliable seal at the tube interface. This type of fitting is installed by HVAC technicians, plumbers, and industrial maintenance professionals working with compressed air, light hydraulic, or instrumentation tubing systems.
This fitting is suited for general-purpose pneumatic and fluid distribution applications in both light commercial and industrial settings. The push-to-connect design allows fast, tool-free tube insertion while the male BSPT thread end secures directly to compatible ported equipment or manifolds. Typical install scenarios include instrument air lines, control system tubing runs, and equipment interface connections where quick assembly and reliable sealing under moderate pressure are required.
Designed for general-purpose use with 4 mm outside-diameter tubing and male BSPT-threaded ports in pneumatic and fluid distribution systems.
Installation is performed by qualified HVAC technicians, plumbers, or industrial maintenance professionals. Depressurize and isolate the system fully before disconnecting or installing any fittings. Ensure tube ends are cut cleanly and squarely and are free of burrs before insertion into the push-to-connect port. Verify thread engagement and confirm the system holds pressure before returning to service.
