8400 SERIES BUNA CUP 2-13/16 X3-1/4X7/32

Ordered as NU8407-0281, this is a Buna-N (Nitrile) U-Cup Seal. The u-cup seal provides low breakaway friction with strong sealing under load.

The material holds up against petroleum-based oils, hydraulic fluids, and propane and butane. Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. It is not the right choice where strong acids or polar solvents are present.

You will find this material specified across general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.

NU8407-0281 ships individually. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
