Description

Overview

1/2 airbrake female coupling connects trailer air brake lines where a non-sealing CA93-style female coupling is required. It suits heavy vehicle air systems that need a 1/2 NPSF female threaded coupling with the correct matching profile.

Features

• 1/2 NPSF female threaded airbrake coupling for trailer air line connection points.
• Non-sealing coupling style for CA93-series airbrake applications.
• CA93-87 reference helps match the coupling against existing air fittings.
• Compact threaded fitting for workshop replacement and air line service work.

Specifications and Materials

This 1/2 airbrake female coupling suits non-sealing female threaded coupling applications in trailer air brake systems.

Part number: 33-A87.

Coupling type: female threaded airbrake coupling. Thread: 1/2 NPSF. Seal type: non-sealing.

Use the AS 4945 air-pressure braking coupling guidance when checking coupling requirements for heavy vehicle air brake systems.

Compatibility and Fitment

Match the coupling profile, thread type and sealing style before ordering. Also check the mating hose coupling, suzi coil end and trailer air line layout, because sealing and non-sealing CA93 fittings must not be mixed without confirming the air system requirement.

Compliance and Safety

Inspect the coupling, hose end and thread before fitting. Replace damaged or worn air fittings instead of reusing parts with poor thread engagement or air leakage. Then test the air brake line for leaks and confirm the brake system operates correctly before returning the trailer to service.

Trailer Applications

Workshops use the 1/2 airbrake female coupling during trailer air line repairs, suzi coil connection work and airbrake coupling replacement. It suits parts-counter matching where the buyer needs the non-sealing CA93-87 style rather than the sealing CA93-35 version.
