Push-to-connect Wye fitting for air systems

This brass and reinforced-nylon fitting joins three 5/32 in tubes in a Y configuration. All three ports use push-to-connect ends for tool-free assembly. It is supplied in a pack of 10 pieces. Suitable for pneumatic plumbing in automotive and workshop environments.

Suited to low-pressure pneumatic networks

Installers building or repairing compressed-air lines with 5/32 in tubing will find this fitting convenient. It does not accept threaded pipe, larger diameters or liquid-service ratings. Systems that require metal-to-metal seals, high-temperature resistance or different tube sizes need alternative components.

Three-port push-to-connect geometry

The defining characteristic is the Y-shaped body with three identical 5/32 in push-to-connect ports. This layout splits or merges airflow in a single plane without adapters. Confirm the tube outer diameter matches 5/32 in before ordering.

Questions about this item

What tube size fits the 5/32 in push-to-connect ports on this Y union?

The three ports accept 5/32 in or 4 mm outer-diameter tubing, so use that exact size for a secure push-fit seal.

How do you install the push-fit connections without leaks?

Cut the tube square, deburr the end, then push it firmly into each port until it bottoms out; the internal collet and O-ring grip and seal automatically.

When should the brass and fiberglass-reinforced nylon body be replaced?

Replace the fitting if the body shows cracks, the collet teeth no longer hold the tube, or the O-ring weeps air under system pressure.
