Description

Overview

The 5/8 x 1/2 NPT male connector joins 5/8-inch outside-diameter nylon air-brake tubing to a 1/2-inch NPTF female port. Its straight brass body connects the air line directly to a valve, manifold or other compatible pneumatic component without a separate compression nut or olive.

Features

• Push-in connection accepts 5/8-inch (15.9mm) OD nylon tubing.
• 1/2-inch NPTF tapered male pipe thread.
• Integrated gripping mechanism and release collet.
• Brass hexagonal body provides a tightening surface.

Specifications and Materials

This DOT push-to-connect fitting combines a brass body, internal tube seal and reusable collet. The tube connection grips the outside diameter, while the threaded end joins a matching female pipe port. No separate compression sleeve or tube nut is needed.

Part number: DQ68DOT1008.

Compatibility and Fitment

Before ordering, confirm the nylon tube measures 5/8 inch across its outside diameter. Also check that the receiving port accepts 1/2 NPTF rather than BSP or metric threads. The 5/8 x 1/2 NPT male connector needs sufficient clearance for straight tube entry without sharp bending.

Compliance and Safety

Depressurise the circuit before installation. Cut the nylon tube squarely, remove damaged ends and insert it fully into the collet. Follow the correct tapered-thread sealing and tightening procedure. Then restore pressure and leak-test both connections.

Trailer Applications

Workshops use these straight connectors on compatible trailer air-brake valves, suspension controls and auxiliary pneumatic systems. They suit installations with 5/8-inch nylon air lines terminating at 1/2 NPTF ports.
