QR-1 Quick Release Valve (1) 1/2in-14 Supply Port (2) 1/4in-18 Delivery Ports Part number: EM37560 OE MFG: MACK OEM Reference: 745-229844 Cross Reference: GMC TRUCK : 2428235; MACK : 745-229844; NAVISTAR : 1693129C91 | PAI : 3756 Product Class: Air Valves & Kits The PAI EM37560 is a QR-1 quick release valve with one 1/2in-14 supply port and two 1/4in-18 delivery ports. As heavy duty diesel truck parts, quick release valves vent downstream air directly to atmosphere when control pressure is released, allowing pneumatic brakes or other air-operated circuits to respond without routing exhaust air back through the control valve. MACK lists 745-229844 as the OEM reference; additional cross-references include GMC Truck 2428235 and Navistar 1693129C91. Show more
