METRIC NITRILE V SEAL 140A (Type A)

Ordered as FVB-0140-A, this is a Buna-N (Nitrile) Type A V-Ring Seal measuring a nominal shaft size of 140A. The v-ring seal acts as a primary or secondary exclusion seal that flings dirt and water away as the shaft turns.

The material holds up against petroleum-based oils, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for low compression set under sustained load and an economical choice for high-volume maintenance programs. Exposure to automotive brake fluid or polar solvents will shorten service life.

It sees regular use in general industrial maintenance, fluid power, and agricultural equipment.

FVB-0140-A ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
