-442 BLUE FKM 75D O-RING

V75MD442 is an AS568-442 blue Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 7.225 in (183.52 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.775 in (197.49 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to chlorinated solvents, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include oil and gas, high-temperature process equipment, and semiconductor equipment.

This item is sold individually under part number V75MD442. Nominal inside diameter is listed as 7 1/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
