A quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for low compression set under sustained load and economical choice for high-volume maintenance programs.

It should not be specified for service in ketones or ozone and direct sunlight. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.
