Description

Overview

Air brake male coupling 1/2″ NPT connects truck and trailer air brake adaptors where a non-sealing male threaded coupling suits the existing air line setup. It suits quick connection points used with suzi coils, trailer adaptors and air brake coupling hardware.

Features

  • 1/2″ NPT male threaded coupling.
  • Non-sealing coupling style for truck and trailer air brake connections.
  • CA93 / SA93 style coupling reference family.
  • Used with suzi coils and matching trailer air brake adaptors.

Specifications and Materials

This air brake male coupling 1/2″ NPT matches the CA93-85 and SA93.85 style 1/2″ male non-sealing coupling reference. Check the thread type, coupling style and matching adaptor before ordering, because sealing and non-sealing couplings are not the same service part.

Part number: 33-A85.
