The NORGREN C01250428 is a straight push-to-connect male connector fitting designed for tube-to-male BSPT connections in pneumatic and fluid control systems. Machined from brass, this fitting accepts a 4mm outside diameter tube on one end and threads into a 1/4 inch BSPT male port on the other. It is rated to 150 psi maximum working pressure and handles temperatures from 0 degrees F to 175 degrees F, making it well-suited for compressed air lines, light hydraulic circuits, and instrument tubing runs. Plumbers, pipefitters, and pneumatic system technicians are the typical installers of this type of fitting.
This fitting is used in residential and light commercial pneumatic systems, compressed air distribution panels, fluid power assemblies, and instrumentation lines wherever a straight inline transition from a push-to-connect tube port to a BSPT male threaded port is required. Its compact overall length of 23.2mm keeps it practical in tight panel or manifold installations. The nitrile O-ring internal seal maintains a reliable connection across the rated pressure and temperature range.
Designed as an OEM-style replacement or new-installation straight connector for pneumatic and fluid systems using 4mm OD tubing with 1/4 inch BSPT male threaded ports.
Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and isolate the system completely before removing or installing any fittings. Apply appropriate thread sealant to the BSPT male threads per the system fluid compatibility requirements. Inspect the push-to-connect collet and O-ring for damage before assembly, and confirm full tube insertion before restoring system pressure.
