-443 BLACK FKM 75D O-RING

Ordered as V70443, this is an AS568-443 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 7.475 in (189.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.025 in (203.84 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists engine and transmission fluids, many acids, and chlorinated solvents. Viton® (FKM) is specified for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

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

V70443 ships individually. Unit weight is approximately 43.867 g. Check the compound against your process media, pressure and temperature before committing to a design.
