ARO 637309-TT PTFE 3/4 in Diaphragm Pump Fluid End Repair Kit

The ARO 637309-TT is a new, genuine OEM fluid end repair kit manufactured by ARO (Ingersoll Rand) for use with ARO 3/4 in air-operated double-diaphragm (AODD) pumps. The kit contains PTFE diaphragm(s), PTFE check valve balls, PTFE seat(s), and a complete set of O-rings and seals sufficient to rebuild the fluid end of the pump, along with a packet of Lubriplate grease (ARO P/N 94276) for assembly. Individual components visible in the kit include: diaphragm (green, center-molded PTFE), valve balls (white PTFE, qty 4), valve seat (Y186-51, qty 2), diaphragm plate (Y328-237, qty 4), O-rings Y325-202 (qty 2), Y325-117 (qty 2), Y325-118 (qty 2), and an air valve O-ring/gasket set, covering all fluid-contact wear parts. The "-TT" suffix in the ARO part numbering convention designates PTFE diaphragm and PTFE ball/seat configuration, making this kit suited for chemical transfer, solvent, and fluid applications requiring fluoropolymer wetted materials. This kit is assembled in the USA with domestic and foreign components as noted on the box label.
