Description

Overview

The 3/16 air brake union tee connects three matching 3/16-inch outside-diameter nylon air tubes through one compact T-shaped fitting. It can divide a straight pneumatic line into a branch or bring two lines into a shared run without threaded adaptors, loose olives or compression nuts.

Features

• Three equal push-in ports for 3/16-inch OD tube
• Tee configuration supports straight-through and branch routing
• Reusable connections release by depressing each collet
• Compact brass body for confined trailer air-line layouts

Specifications and Materials

Product type: DOT push-to-connect air brake fitting. Configuration: equal union tee. Connections: three 3/16-inch OD tube ports. Body material: brass. The tube connections use collets that retain compatible nylon air brake tube without separate compression hardware.

Part number: DQ64DOT03.

Compatibility and Fitment

Measure all three tubes across their outside diameter before ordering. Each port must receive 3/16-inch imperial tube, so do not substitute 5/32-inch, 1/4-inch or 4mm line. Also check the available space around the branch, because the tube must enter each collet straight and remain free from side loading.

Related Parts

Choose the matching tube-size version when the existing line is not 3/16 inch.

Compliance and Safety

Depressurise the complete circuit before cutting or disconnecting any tube. Make clean square cuts, remove scratched or flattened material and push each line fully into its port. Then restore pressure gradually, inspect all three connections for leakage and confirm that each tube remains securely retained.

Trailer Applications

The 3/16 air brake union tee suits compatible trailer air brake, air suspension and auxiliary pneumatic circuits that need a compact branch in a small control or signal line. Its equal-port layout keeps the same tube size through the run and branch, which avoids an unintended reduction at the junction.
