This ring set is made by PAI for air compressor rebuilds on Navistar and Mack trucks, sold complete as one set per pack. The rings seat around the compressor's pistons in the cylinder bore, sealing combustion pressure and managing oil to keep the air brake system charging properly. It is intended as a full rebuild solution rather than a single component replacement.
