Norgren 120820400 Union Y Fitting 1/4 Inch Od

Product Description

The NORGREN 120820400 is a Pneufit push-to-connect parallel union Y fitting designed for tube-to-tube pneumatic connections. It accepts 1/4 inch OD tubing and requires no tools for assembly — tubing inserts and locks in place, making it a fast, reliable choice for branching pneumatic lines. Constructed from nickel-plated brass, the fitting handles a maximum working pressure of 260 psi and operates across a temperature range of -4 degrees F to 175 degrees F. Licensed HVAC techs, pneumatic system installers, and industrial maintenance professionals use this fitting in compressed air and pneumatic control circuits.

This fitting is suited for light industrial and commercial pneumatic plumbing where a single tube run needs to split into two parallel branches without flow restriction. The Y configuration supports clean inline branching in tubing assemblies. It is appropriate for use in instrument air lines, pneumatic actuator supply circuits, and HVAC pneumatic control networks where 1/4 inch OD tubing is standard. Its compact 1.51 inch overall length keeps installations tight in panel and cabinet environments.

Key Features

• Push-to-connect design — no tools or ferrules required for tube insertion
• Parallel union Y configuration for splitting one pneumatic line into two branches
• Nickel-plated brass construction for corrosion resistance in compressed air service
• Rated to 260 psi maximum working pressure
• Operating temperature range of -4 degrees F to 175 degrees F
• Vacuum-rated to 29.5 in-Hg for low-pressure and vacuum circuit applications

Compatibility

Designed as an OEM-style replacement or direct-use fitting for pneumatic tubing systems utilizing 1/4 inch OD tubing in compressed air, instrument air, and pneumatic control applications.

Installation Notes

Depressurize and isolate the pneumatic circuit completely before removing or installing any push-to-connect fittings. Ensure tubing ends are cut cleanly and squarely with no burrs before insertion to achieve a proper seal. This fitting is typically installed by qualified pneumatic technicians or licensed HVAC mechanics working on pneumatic control systems. Verify that system operating pressure and temperature do not exceed the rated maximums for this fitting.
