This ring set is made by PAI for rebuilding heavy-duty air compressors used on Mack applications, sold as one each. The rings seat around the compressor pistons within the cylinder bore, sealing combustion pressure and managing oil control to keep the air brake system charging properly. It serves as a replacement for the compressor ring set originally fitted to these Mack units.
