The PAI EM37550 is a QR-1 quick release valve with two 1/4-18 side ports and one 3/8-18 top port, constructed with an aluminum body. As heavy duty diesel truck parts, quick release valves ordinarily vent downstream air rapidly when control pressure is released, supporting responsive operation in pneumatic systems. The port arrangement and thread sizes provide concrete identification details when matching air-line connections. MACK lists 745-229813 as the OEM reference, also cross-referenced under OTHER as 745-229813.
