Norgren 94451404M Union Tee Fitting 1/4 Inch Od Brass

Product Description

The NORGREN 94451404M is a push-to-connect union tee tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Constructed from brass, this fitting accepts 1/4-inch outside diameter tubing on all three ports and holds a maximum working pressure of 150 psi. The push-to-connect design allows fast, tool-free tube insertion, making it a practical choice for compressed air lines, control tubing runs, and similar low-to-medium pressure plumbing tasks. The Buna O-ring provides a reliable seal across a wide service temperature range, from -40 degrees F to 212 degrees F.

This union tee fitting is suited for residential and light commercial pneumatic control systems, HVAC equipment tubing runs, and general-purpose compressed air distribution where a branch connection is needed mid-line. It is commonly installed by HVAC technicians, plumbers, and industrial maintenance mechanics working with 1/4-inch OD soft copper, nylon, or polyurethane tubing. The three-port tee configuration allows a single inline tube run to branch to a third line without additional adapters or fittings.

Installation Notes

Installation is performed by HVAC technicians, plumbers, or qualified mechanical trades. Depressurize and isolate the affected line completely before removing or inserting any fitting. Ensure tubing is cut cleanly and squarely and that the tube end is free of burrs before inserting into the push-to-connect port. Verify the tubing material and system fluid are compatible with brass fittings and Buna O-rings before installation.
