Expect good resistance to petroleum oils and fuels, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or amines will shorten service life.

It sees regular use in high-temperature process equipment, aerospace, and semiconductor equipment.

V5.7X269.3 ships individually. Unit weight is approximately 40.682 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
