-341 BLACK FKM 75D O-RING

V70341 is an AS568-341 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 3.475 in (88.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.895 in (98.93 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The material holds up against engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

You will find this material specified across automotive fuel systems, high-temperature process equipment, and semiconductor equipment.

Stocked as V70341 and sold individually. Unit weight is approximately 12.093 g and nominal inside diameter is listed as 3 1/2 inch.
