The PAI LSV-5678 is an adjustable safety valve with a 150 psig cracking-pressure specification and a male (1)1/4-18 NPT connection. Safety valves are heavy duty diesel truck parts that release pressure when a protected air or fluid system reaches the valveâs set point, limiting overpressure within that system. The adjustable pressure and defined NPT thread size provide important details when matching this valve to service requirements. MACK lists 745-205105 as the OEM reference, with NAVISTAR 1676692C1 as an additional cross-reference.
