Norgren C00230406 Stem Expander Tube Fitting Brass

Product Description

The NORGREN C00230406 is a straight push-to-connect stem expander tube fitting designed for use in pneumatic and fluid control plumbing lines. Constructed from brass, it connects a 6 mm outside diameter tube to a 4 mm outside diameter stem using a push-to-connect mechanism, eliminating the need for additional fittings or tools at the tube end. Rated to 150 psi maximum working pressure, this fitting is suited for compressed air and compatible fluid systems operating between 0 degrees F and 175 degrees F. With an overall length of 41 mm, it is a compact inline solution for technicians working in tight plumbing and pneumatic assemblies.

This fitting is appropriate for light industrial, commercial, and mechanical system applications where a reliable push-to-connect tube-to-stem transition is required. It is commonly installed in pneumatic control circuits, instrumentation lines, and fluid distribution systems. The straight configuration makes it a straightforward drop-in component for runs that do not require directional change. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers for this type of fitting in both new construction and service scenarios.

Key Features

• Brass construction provides durability and corrosion resistance in pneumatic and compatible fluid service
• Push-to-connect design allows fast, tool-free tube insertion at the tube end
• Rated to 150 psi maximum working pressure
• Nitrile O-ring sealing material for reliable performance across the rated temperature range
• Straight stem expander geometry suits inline installations without directional change
• Compact 41 mm overall length fits tight assembly spaces

Compatibility

Designed as an OEM-style push-to-connect tube-to-stem fitting for pneumatic and fluid control systems requiring a 6 mm OD tube connection to a 4 mm OD stem port.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and isolate the pneumatic or fluid circuit completely before removing or installing any fittings. Ensure the tube end is cut cleanly and squarely with no burrs before insertion into the push-to-connect end to achieve a proper seal. Verify system pressure and temperature do not exceed the rated 150 psi and 175 degrees F limits after commissioning.
