-903 BLACK FKM 90D O-RING

Ordered as V90903, this is an AS568-903 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 0.301 in (7.65 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.429 in (10.9 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or low-molecular-weight organic acids.

Typical settings include semiconductor equipment, automotive fuel systems, and high-temperature process equipment.

Stocked as V90903 and sold individually. Unit weight is approximately 0.1132 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
