The PAI LPP-5591 is a push pull valve with an automatic tripper, identified for air-system service by its defined thread and port configuration. As heavy duty diesel truck parts, push pull valves control air flow between supply, delivery, and exhaust circuits, allowing a pneumatic function to be engaged or released through valve movement. This valve uses a 7/8-20 thread, a 1 1/8-27 NPT supply port, and 1 1/4-18 NPT delivery and exhaust ports. MACK lists 745-288746 as the OEM reference; additional MACK cross-references are 20QE3111 and 745-279159.
