This ring set is made for rebuilding the air compressor on Mack applications, packaged one set per sell pack. The rings seat around the compressor's pistons within the cylinder bore, sealing combustion pressure and managing oil flow so the compressor charges the truck's air brake system properly. It is a replacement for the applicable Mack air compressor.
