The PAI LCV-4057 is a female check valve with a 2 1/2-14 NPT threaded connection, identified by Benchmark Technology Group OEM reference 800370. As heavy duty diesel truck parts, check valves control one-way flow in an air or fluid circuit and prevent reverse movement through the system. The female thread specification supports accurate connection matching, while Mack cross-reference 745-800370 provides additional part-number context.
