The PAI EM36170 is an RE-6 relay valve with one 1/2-inch supply port, four 3/8-inch delivery ports, and one 1/4-inch service port. As heavy duty diesel truck parts, relay valves normally use a control signal to regulate air delivery within a vehicle's pneumatic braking system, and this port arrangement defines the listed configuration. Mack lists 745-280375 as the OEM reference, with 0811A and 280375 as additional cross-references.
