5.33MM CS X 142.88MM ID BLACK FKM 75D

Part number V5.33X142.88 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 142.88 mm (5.625 in), a cross section of 5.33 mm (0.21 in), and an outside diameter of 153.54 mm (6.04 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is valued for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across chemical processing, oil and gas, and automotive fuel systems.
