-323 BLACK FKM 75D O-RING

This o-ring is supplied in AS568-323 black Viton® (FKM) 75 Shore A measuring an inside diameter of 1.287 in (32.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.707 in (43.36 mm), catalogued under part number V70323. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. This material stands up to many acids, chlorinated solvents, and aromatic hydrocarbons. The material carries a published service range of -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.

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and semiconductor equipment.

Stocked as V70323 and sold individually. Unit weight is approximately 4.9571 g and nominal inside diameter is listed as 1 5/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
