-443 BLUE FKM 75D O-RING

This o-ring is supplied in AS568-443 blue Viton® (FKM) 75 Shore A measuring 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), catalogued under part number V75MD443. It delivers dependable bidirectional sealing in a compact groove envelope.

Viton® (FKM) is widely chosen for very low compression set at elevated temperature and outstanding high-temperature capability. The material holds up against aggressive chemicals, engine and transmission fluids, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across chemical processing, high-temperature process equipment, and automotive fuel systems.

V75MD443 ships individually. Nominal inside diameter is listed as 7 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
