Description

Overview

The 1/2 air brake union tee connects three matching 1/2-inch outside-diameter nylon air tubes through one compact T-shaped push-in fitting. It lets a straight pneumatic line branch without threaded adaptors or separate compression nuts while keeping the same tube size through all three ports.

Features

• Three equal push-in ports for 1/2-inch OD nylon tube
• Tee layout supports straight-through flow with a branch connection
• Reusable connections release by depressing the collet
• Compact brass body for trailer air-line layouts

Compatibility and Fitment

Measure all three tubes across their outside diameter before ordering. Each port is for 1/2-inch imperial tube, so do not substitute 12mm or another nearby size. Allow enough space for each tube to enter the collet straight without side loading.

Related Parts

Choose the matching tube-size version where the existing line is smaller or larger.

Compliance and Safety

Depressurise the air circuit before cutting or disconnecting tube. Make a clean square cut, remove scratched or flattened tube and push each line fully into its port. Restore pressure gradually, check all three connections for leakage and confirm each tube remains securely retained.

Trailer Applications

The 1/2 air brake union tee suits compatible trailer air brake, air suspension and auxiliary pneumatic circuits that need a compact branch while retaining 1/2-inch tubing through the junction. Its equal-port layout keeps the run and branch at the same tube size.
