Description

Overview

The 1/4 NPT push-in elbow connects 1/4-inch outside-diameter nylon air tube to a 1/4 NPT male port at a 45-degree angle. Its swivel body lets the fitting align during installation, helping the tube clear nearby hardware without the tighter turn of a 90-degree elbow.

Features

• 45-degree swivel male elbow configuration
• Push-in collet for 1/4-inch OD nylon tube
• 1/4-18 NPTF male threaded connection
• Reusable tube connection released by depressing the collet

Compatibility and Fitment

Choose this 1/4 NPT push-in elbow only when both connection sizes match. Measure the tube across its outside diameter, confirm the female pipe port and check outlet clearance. The main ordering risks are selecting a 1/8 NPT thread, confusing tube size with pipe size or ordering the fixed non-swivel version.

Compliance and Safety

Depressurise the circuit before installation. Cut the nylon tube square, remove scored or deformed material and push the tube fully into the collet. Then pressure-test the connection and confirm secure tube retention. Use the swivel for installation alignment, not as a continuously rotating joint.

Trailer Applications

This fitting suits compatible trailer air brake, air suspension and pneumatic control circuits where a 1/4-inch nylon line approaches a threaded port at 45 degrees. The angled outlet can reduce tube strain around valves, brackets and chassis components.

Why Choose ICS Trailers

Push-in elbows can look identical while using different tube sizes, pipe threads and swivel arrangements. Compare the old fitting markings and tube outside diameter before ordering, or send clear photos of the fitting and port if the connection remains uncertain.
