-347 BLACK FKM 90D O-RING

V90347 is an AS568-347 black Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 4.225 in (107.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.645 in (117.98 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Viton® (FKM) is specified for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The compound resists engine and transmission fluids, chlorinated solvents, and aggressive chemicals. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

You will find this material specified across chemical processing, semiconductor equipment, and aerospace.

V90347 ships individually. Unit weight is approximately 14.605 g and nominal inside diameter is listed as 4 1/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
