Norgren C20840402 Push-to-connect Tube Stem Fitting

Product Description

The NORGREN C20840402 is a push-to-connect tube to stem tube fitting designed for general-purpose pneumatic and fluid-transfer applications. Constructed from brass, this fitting accepts 5/32 inch outside diameter tubing and features a 1/4 inch stem outside diameter. The push-to-connect design allows fast, tool-free tube insertion while maintaining a secure seal under pressure. It is rated to a maximum working pressure of 150 psi and operates across a temperature range of 0 to 175 degrees F. An integrated nitrile O-ring provides reliable sealing performance. This fitting is typically installed by HVAC technicians, plumbers, and instrumentation specialists working with small-bore tubing assemblies.

The C20840402 is suited for general-purpose fluid and pneumatic control lines in both residential and light commercial settings. Common applications include low-pressure instrument air lines, control tubing runs, and sensor connection points where a reliable, compact tube-to-stem interface is required. Its brass body resists corrosion in typical indoor and controlled-environment installations.
