This tractor protection valve fits Mack Universal applications and is a replacement, sold individually. It works by automatically shutting off trailer air supply if pressure drops suddenly, such as in a breakaway or major leak, keeping air in the towing tractor's own system intact. It also fits certain Navistar applications.
