ARO 77803 is a nitrile O-ring sized .275 in. x 1.837 in. O.D. It is listed for 2-ball use on ARO 612041-3 and 612042-1 pumps.
WHERE TO BUY?
The ARO 77803 is a nitrile O-ring with a listed size of .275 in. x 1.837 in. O.D. The catalog assigns it to 2-ball pump applications, and two ARO pumps call for it in their parts lists.
Compressed in its groove between two parts, the ring blocks leaks at that joint. Nitrile, also known as Buna-N, is a general-purpose elastomer widely used with petroleum oils and greases. That lines up with the 612041-3, which its catalog title describes as an oil pump for 55-gallon containers. Compare the size and your pump model number with the parts list before ordering. Measuring the old ring helps rule out a mix-up.
