Viton 70-211-Black-Pk25

SB-V70211-25 is an AS568-211 black Viton® (FKM) 70 Shore A O-Ring with an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint. Supplementary detail from the product record: 1.0625IDX.8125"ODX.125"CS.

The compound resists engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with low-molecular-weight organic acids or hot water and steam.

You will find this material specified across automotive fuel systems, semiconductor equipment, and oil and gas.
