Description

Overview

The 1/2 push-in elbow connects 1/2-inch outside-diameter nylon air tube to a 1/4 NPT male port while directing the line through a 45-degree angle. Its swivel base allows the outlet position to be set during installation, helping the larger tube clear valves, brackets and chassis components without being forced into a tight bend.

Features

• 45-degree swivel male elbow configuration
• Push-in connection for 1/2-inch OD nylon tube
• 1/4-18 NPTF male pipe thread
• Reusable tube connection released by depressing the collet
• Brass construction for compatible air brake plumbing

Compatibility and Fitment

Select this 1/2 push-in elbow only when the tube and threaded port both match. Measure the tube across its outside diameter and confirm the receiving port is 1/4 NPT rather than BSP or metric. Do not substitute 12mm tube, as its outside diameter does not match the specified 1/2-inch collet and seal.

Compliance and Safety

Depressurise the pneumatic circuit before installation or removal. Cut the nylon tube square, remove burrs and damaged material, then push the tube fully through the collet to the internal stop. Use the swivel base for installation alignment rather than continuous rotation. Pressure-test both connections and confirm the tube remains secure before returning the trailer to service.

Trailer Applications

This fitting suits compatible trailer air brake, air suspension and auxiliary pneumatic systems where a 1/2-inch nylon line enters a smaller 1/4 NPT valve, manifold or reservoir port. The shallow outlet angle assists line routing where a straight connector or 90-degree elbow would create poor clearance or tube strain.

Why Choose ICS Trailers

Tube diameter and pipe thread size describe different connections on this fitting, even though both are stated in inches. If the old fitting lacks readable markings, send clear photos with the tube outside diameter and thread measurement before ordering.
