Description

Overview

The push-in union tee joins three matching 1/4in nylon air lines at one junction in trailer air brake and auxiliary pneumatic circuits. Its equal-port layout supports a three-way split or merge without a threaded branch.

Features

• Three push-to-connect ports suit 1/4in imperial tube OD.
• Equal tee geometry keeps every connection the same size.
• Brass body uses integral collets and seals.
• Depress each collet to release the tube for servicing.

Specifications and Materials

This fitting comes as one complete tee with all three push-in connections integrated into the body. No separate tube nuts, olives or compression sleeves are required. Use compatible D.O.T. nylon air brake tubing with the correct outside diameter and wall thickness.

Part number: 88-014-04.

Compatibility and Fitment

Match the push-in union tee to 1/4in imperial tube at all three ports. Common ordering errors include choosing a 6mm metric tee, a reducing tee or a tee with a threaded branch. Measure the tube outside diameter because 1/4in and nearby metric sizes can look similar. These cross-references show where this part replaces the part numbers and applications listed. Some installations may need minor changes. DQ64DOT04, 1864X4

Compliance and Safety

Depressurise the circuit before removing a line. Cut each tube square, remove burrs and damaged sections, then push the tube fully home. Afterwards, pull back gently and pressure-test all three joints. Keep brackets and chassis edges clear of the release collets.

Trailer Applications

Workshops use this equal tee to divide one 1/4in air line into two paths or combine two lines into one route. Trailer applications include brake control plumbing, air suspension controls, tanks, valves, tyre inflation circuits and other fixed pneumatic lines.
