Description

Overview

The 1/4 push-in elbow connects 1/4-inch outside-diameter nylon tube to a 1/8 NPTF male port. Its 45-degree swivel layout changes the air-line direction without the tighter turn of a 90-degree elbow.

Features

• Push-in connection for 1/4-inch outside-diameter nylon tube
• 1/8-27 NPTF male pipe thread
• 45-degree swivel male elbow configuration
• Brass fitting body for trailer pneumatic service
• Collet can be depressed to release the tube
• Pre-applied thread sealant on the male pipe connection

Compatibility and Fitment

Confirm that the nylon line measures 1/4 inch across its outside diameter and that the threaded port is 1/8-27 NPTF female. The main ordering risks are confusing tube outside diameter with bore size, substituting a 1/4-inch pipe thread, or selecting a fixed elbow where the swivel configuration is needed.

Compliance and Safety

Depressurise the air system before removing or installing the fitting. Cut the nylon tube square, remove scoring or deformation from the tube end and push it fully into the collet. Do not build up extra sealant over the pre-applied thread coating. Pressure-test the completed connection and check that the tube remains secure before returning the trailer to service.

Trailer Applications

This fitting suits compatible trailer air brake, air suspension and pneumatic control lines where 1/4-inch nylon tube must approach a 1/8 NPTF port at a 45-degree angle. The swivel body helps align the tube away from nearby valves, brackets and chassis hardware.

Why Choose ICS Trailers

Push-in elbows can share the same basic shape while using different tube sizes, thread sizes and swivel arrangements. Compare the tube outside diameter, pipe thread and required line angle before ordering. Send through the old fitting markings and clear connection photos if any of these details are uncertain.
