8400 SERIES BUNA CUP 7-3/8 X 8 X 5/16W

The NU8410-0737 is a Buna-N (Nitrile) U-Cup U-Cup Seal measuring a 7-3/8 inch inside diameter, an 8 inch outside diameter, and a height of 5/16 inch. This u-cup seal uses a U-shaped profile that system pressure forces outward, tightening the seal as pressure rises.

The material holds up against petroleum-based oils, many alcohols, and propane and butane. Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. It is not the right choice where polar solvents or automotive brake fluid are present.

Common environments for this compound include agricultural equipment, construction equipment, and automotive.
