Description

Overview

The 8mm air brake union tee splits or combines airflow through three equal push-in connections. All three ports accept 8mm outside-diameter nylon tube, so the fitting can extend a line while adding a branch without threaded adaptors. Its compact T-shape suits repairs where the new branch must leave the main tube run at 90 degrees.

Features

• Three equal push-in ports accept 8mm metric air brake tube.
• Union tee layout joins two aligned lines with one perpendicular branch.
• Brass body carries reusable collets and internal tube seals.
• Each tube connection releases by pressing the collet during servicing.

Specifications and Materials

The fitting uses CA360 and CA377 brass with NBR O-rings around the tube connections. The matching design carries a maximum working pressure of 150 PSI and operates from -40°C to 104°C. It suits compatible SAE J844 nylon air brake tubing.

Part number: 88-M014-08.

See the manufacturer technical specifications for the matching fitting design

Compatibility and Fitment

Measure every tube across its outside diameter before ordering. The main mismatch risk is using 5/16-inch tube because it is close to 8mm but not the same size. Also confirm the system needs an equal tee rather than a reducing tee or a threaded branch. The 8mm air brake union tee requires clean tube ends cut square and pushed fully to the internal stops.

Compliance and Safety

Depressurise the circuit before cutting or disconnecting tube. Inspect each tube end for scoring, flattening or contamination because damage at any of the three seals can create a leak. After assembly, pull back lightly on each line, then restore pressure and test every connection before returning the trailer to service.

Trailer Applications

Workshops use this equal tee to add a branch to 8mm air brake, air suspension and auxiliary pneumatic lines. Typical positions include control-valve plumbing, reservoir circuits and equipment feeds where all three tube runs use the same diameter.
