The NORGREN C20230602 is a straight push-to-connect tube-to-stem fitting designed for use in pneumatic and fluid distribution lines. The fitting accepts 5/32-inch OD tubing on one end and connects to a 3/8-inch OD stem on the other, forming a secure, tool-free tube connection. Constructed from brass, it is rated for a maximum working pressure of 150 psi and handles temperatures from 0 degrees F to 175 degrees F. The nitrile O-ring provides a reliable seal across a broad range of fluid media. Licensed HVAC technicians, plumbers, and pneumatic system installers routinely use this type of fitting to terminate tubing runs or interface tubing to manifold stems and valve bodies.
This fitting is suited for residential and light commercial applications where 5/32-inch OD tubing must be connected to a 3/8-inch stem port. Typical installation scenarios include pneumatic control lines, condensate or low-pressure fluid circuits, and instrumentation tubing. The straight configuration simplifies inline connections without requiring bends or adapters. Its compact size and brass construction make it a practical choice for tight mechanical spaces or control panel assemblies where a permanent, vibration-resistant connection is needed.
Designed as an OEM-style push-to-connect tube fitting for systems using 5/32-inch OD tubing with a 3/8-inch stem connection in pneumatic, HVAC control, or fluid distribution applications.
Installation is typically performed by licensed HVAC technicians, plumbers, or qualified pneumatic system technicians. Before servicing any pressurized line, isolate and depressurize the circuit fully and confirm zero pressure before disconnecting or inserting tubing. Ensure tubing is cut cleanly and squarely with a proper tube cutter to guarantee a leak-free seal against the O-ring. Verify that the tubing OD and stem OD match the fitting specifications before assembly.
