This discharge valve seat comes as a set of five for rebuilding air brake discharge valve assemblies on Mack and Navistar trucks. Each seat provides the machined surface the valve element seals against, keeping compressed air from flowing back through the compressor cylinder once discharged. Made by PAI, the pack lets a shop cover several valve rebuilds without ordering seats individually.
This unit is sold in packs of 5.
