Description

Overview

The Emergency Gladhand Coupling 1/2in NPT provides a secure connection for the trailer emergency air line between the prime mover and trailer. It uses a standard gladhand interface so operators can connect and disconnect quickly during hook-up. This helps maintain consistent air delivery when the rig is exposed to vibration and road grime.

Features

• Suits emergency air line connections on heavy vehicle trailer systems
• Includes a coupling seal to support an airtight connection
• Uses a corrosion resistant connector plate for harsh environments
• Delivers a durable die cast aluminium body for daily service work

Specifications and Materials

Part number: AB1386.

Emergency Gladhand Coupling 1/2in NPT uses a 1/2in NPT port and suits common air brake hose and pipe fittings. The connector plate uses a protective coating to resist corrosion and help maintain a clean seal face over time.

Compatibility and Fitment

This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 11451, 278851, 441016, E9108, W79851

Confirm your trailer uses the emergency (supply) line configuration and the correct hose orientation before ordering. If your setup uses a different port thread or a non-standard mount, choose the matching coupling style instead. Pair the coupling with a fresh seal if you see flattening or cracking on the old one.

Compliance and Safety

This design targets SAE J318 style requirements for gladhand couplings used on air brake systems. Inspect the seal face, confirm the locking lugs engage cleanly, and replace worn seals before they leak. Otherwise, air loss can extend compressor run time and reduce brake response consistency.

Trailer Applications

Emergency Gladhand Coupling 1/2in NPT suits semi trailers, B-doubles, dog trailers, and other heavy vehicle combinations that use a dedicated emergency air line to charge reservoirs and support brake control. It suits fleet maintenance, workshop repairs, and trailer builds where a standard emergency coupling is required. It also suits routine service work when you replace hoses, suzies, or trailer air fittings.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

Similarly, verify port thread, seal style, and line function so the replacement matches your air system layout. Then test for leaks with a soapy water check after installation.
