Description

Overview

The 3/8 tube x 1/2 NPT push-in male connector provides a straight connection between imperial nylon air-brake tube and a larger threaded pneumatic port. This size suits installations that need a 3/8″ air line connected directly to a component with a 1/2 NPT female thread.

Features

• Push-in connection accepts 3/8″ outside-diameter nylon tube
• 1/2 NPT male thread connects to a compatible female port
• Red pre-applied thread sealant covers the male pipe thread
• Brass body includes a 22mm hex section for controlled tightening

Specifications and Materials

This straight D.O.T. air-brake fitting combines a 3/8″ push-in tube connection with a 1/2 NPT male thread. The push-in end contains the collet, gripping mechanism and internal seal required to retain compatible tube, so separate compression nuts, olives and tube inserts are not required. Part number: 88-003-0608.

Review the manufacturer male connector specifications

Compatibility and Fitment

Confirm that the air line measures 3/8″ across its outside diameter and that the receiving component has a 1/2 NPT female port. The first measurement refers to the tube size, while the second identifies the male pipe thread. Do not substitute 10mm metric tube, 1/2 BSP thread or a smaller 1/4 NPT connector because these connections are not equivalent.

Cut the tube square and remove burrs before pushing it firmly through the release collet to the internal stop. Pull back lightly to confirm that the tube has engaged. These cross-references show where this part replaces the part numbers and applications listed. Some installations may need minor changes. DQ68DOT0608, 1168X6X8

Compliance and Safety

Depressurise the complete pneumatic circuit before installing the fitting or releasing the tube. Inspect the tube near the sealing point for scoring, flattening, contamination or heat damage. Replace damaged tube rather than attempting to seal it through additional insertion force.

Use the body hex when tightening the male thread and keep the pre-applied sealing compound clear of the air passage. Pressurise the system gradually after assembly, then leak-test both the threaded port and push-in connection before returning the trailer to service.

Trailer Applications

Workshops fit this connector where a 3/8″ nylon air line enters a valve, manifold, reservoir accessory, suspension control or other pneumatic component with a 1/2 NPT female port. Its straight body suits layouts where the tube approaches the component in line and sufficient clearance is available for the larger threaded end.
