ARO Y327-220 Viton O-Ring

The ARO Y327-220 is an O-ring made from Viton, cataloged by ARO (Ingersoll Rand) for diaphragm pumps. An O-ring sits in a groove between two mating parts. When the parts are assembled it is squeezed, forming a static seal that keeps fluid or air from escaping at the joint.

Viton is a fluoroelastomer, a seal material commonly specified where the pumped fluid would attack ordinary rubber. Check that it suits the fluid in your system. If you are rebuilding with one of the service kits below, this O-ring may already be in the box, so compare the kit contents with your parts list before ordering it on its own.
