Norgren C00230804 Push-to-connect Tube Stem Fitting

Product Description

The NORGREN C00230804 is a push-to-connect tube-to-stem tube fitting manufactured from brass and rated for a maximum working pressure of 150 psi. The fitting accepts a 4 mm outside-diameter tube on the push-to-connect end and interfaces with an 8 mm outside-diameter stem. A nitrile O-ring provides the primary seal, making this fitting suitable for pneumatic and fluid-transfer lines where a secure, tool-free tube connection to a threaded or barbed stem is required. Licensed HVAC technicians, plumbers, and pneumatic system technicians commonly install this type of fitting during line assembly or service work.

This fitting is used in pneumatic control systems, fluid distribution manifolds, and instrumentation tubing runs in both residential and light commercial applications. The push-to-connect design allows fast tube insertion without additional tooling, reducing assembly time on multi-connection panels or equipment. It is rated for service from 0 degrees F to 175 degrees F, covering the temperature range found in most standard HVAC and pneumatic control environments.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Brass body construction for corrosion resistance in pneumatic and fluid service
• Rated to 150 psi maximum working pressure
• Nitrile O-ring seal for reliable performance across a wide temperature range
• Operating temperature range of 0 degrees F to 175 degrees F
• 4 mm tube OD connection to 8 mm stem OD for mixed-size line transitions

Compatibility

Designed as an OEM-style push-to-connect tube-to-stem fitting for pneumatic control and fluid-transfer systems using 4 mm OD tubing with an 8 mm OD stem interface.

Installation Notes

Installation is performed by pneumatic technicians, HVAC controls specialists, or plumbers working on instrument air or fluid-transfer lines. Depressurize and isolate the system completely before disconnecting or installing any fittings. Ensure tube ends are cut square and free of burrs before insertion to achieve a proper seal. Verify that all connections hold pressure before returning the system to service.
