Norgren C20230204 Stem Expander Fitting 1/4 in Od Brass

Product Description

The NORGREN C20230204 is a straight push-to-connect stem expander tube fitting designed for general-purpose pneumatic and fluid-transfer applications. It connects tubing with a 1/4 inch outside diameter to a stem with a 5/32 inch outside diameter using a tool-free push-in mechanism secured by an internal collet and nitrile O-ring seal. Constructed from brass, this fitting is rated to 150 psi maximum working pressure and handles temperatures from 0 degrees F to 175 degrees F. The overall length is 1.49 inches and the package weight is 0.0088 pounds. Licensed plumbers, HVAC technicians, and pipefitters install this fitting in low-pressure pneumatic and fluid-line assemblies.

This fitting is suited for general-purpose tube-to-stem connections in residential and light commercial pneumatic systems, instrumentation lines, and other low-pressure service applications. The stem expander design allows it to join tubing to a smaller-diameter stem outlet, making it useful in control circuits, pneumatic actuators, and similar assemblies where tube OD and stem OD differ. The straight configuration keeps the flow path direct with minimal pressure drop.

Key Features

• Push-to-connect collet design allows tool-free tube insertion for fast assembly
• Brass construction provides corrosion resistance in general-purpose service
• Nitrile O-ring seal maintains a leak-free connection across the rated pressure and temperature range
• Rated to 150 psi maximum working pressure
• Operates from 0 degrees F to 175 degrees F
• Stem expander geometry bridges 1/4 inch tube OD to 5/32 inch stem OD in a straight inline configuration

Compatibility

Designed for general-purpose pneumatic and fluid-line applications requiring a push-to-connect tube-to-stem transition. Compatible with 1/4 inch OD tubing connecting to a 5/32 inch OD stem port.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable codes such as IPC or system-specific pneumatic service guidelines. Depressurize and isolate the line completely before disconnecting or installing any fitting. Ensure tubing is cut cleanly and squarely and that the tube end is free of burrs before insertion to maintain a proper collet and O-ring seal. To release the tube, depress the collet release collar before pulling the tube free — do not force the tube out without releasing the collet.
