Description

Overview

The air brake run tee connects two 1/4in nylon tube sections in a straight line while adding a 1/4 NPT male threaded branch. Its swivel body helps orient the tee in compact trailer pneumatic layouts, so the branch can face the required direction without twisting the connected air lines.

Features

• Two push-in ports suit 1/4in outside-diameter nylon air brake tube.
• 1/4 NPT male branch connects to a matching female threaded port.
• Swivel run-tee configuration supports accurate branch orientation during installation.
• Reusable collets release the tube when depressed for service or rerouting.

Specifications and Materials

This brass D.O.T. push-in fitting uses a straight tube-to-tube run with the threaded male connection positioned through the branch. The fitting contains its gripping and sealing components, so no separate tube nut, olive or insert is required for the push-in ends.

Part number: 88-013S-0404.

Compatibility and Fitment

Match this air brake run tee to 1/4in tube OD and a 1/4 NPT female port. Do not confuse the 1/4in tube size with the thread size, and check that a run tee suits the plumbing layout rather than a branch-tee configuration. These cross-references show where this part replaces the part numbers and applications listed. Some installations may need minor changes.

Compliance and Safety

Depressurise the air system before removal. Cut tube ends square, remove scoring or oval sections, then push each tube fully home and pull back gently to confirm engagement. After tightening the threaded branch, pressure-test every connection and check for leakage before returning the trailer to service.

Trailer Applications

Trailer workshops fit this tee where a 1/4in air line must continue straight while feeding a valve, manifold, reservoir or auxiliary pneumatic component through a threaded side port. The swivel action also helps position the branch around chassis rails and nearby hardware.
