8400 SERIES BUNA CUP 7/8 X 1 1/8 X 1/8W

APG stocks the NU8404-0087, a Buna-N (Nitrile) U-Cup Seal. An u-cup seal seals more effectively as system pressure increases, without added squeeze at rest.

Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists water, propane and butane, and greases and lubricants. Applications involving automotive brake fluid or polar solvents call for a different compound.

You will find this material specified across construction equipment, fluid power, and hydraulic and pneumatic systems.

NU8404-0087 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
