Description

Overview

This gladhand coupling service 1/2in NPT fitting connects the service air line between a prime mover and trailer so you can couple air hoses quickly and securely. It uses the standard gladhand interface, so operators can connect and disconnect without tools. The 1/2in NPT port also makes it straightforward to plumb into common service line setups on heavy vehicle trailers. Because air brake reliability matters, it suits applications where consistent sealing and positive engagement are essential.

Features

This gladhand coupling service 1/2in NPT design supports everyday fleet use while keeping installation simple.

• Service air line gladhand coupling for tractor and trailer connections
• 1/2in NPT port for common air line plumbing
• Die cast aluminium body with a corrosion resistant coating
• Designed to meet SAE J318 interface requirements

Specifications and Materials

Compliance and Safety

Gladhand couplings commonly follow SAE J318 interface conventions, but confirm your hose end and port thread before installation. Isolate and depressurise the air system before you remove any fittings. If you see damaged sealing faces or worn locking geometry, replace the coupling rather than forcing a connection. For safety, a qualified technician should pressure-test the system after installation.

Trailer Applications

This gladhand coupling service 1/2in NPT fitting is used on the service air line connection between a prime mover and trailer. It suits semitrailers, B-doubles, dog trailers and other heavy vehicle trailer combinations that use standard air brake hose coupling hardware. It can also suit air coil and service line hose assemblies where a 1/2in NPT port matches the plumbing.
