This o-ring is supplied in black Viton® (FKM) 75 Shore A with an inside diameter of 24.6 mm (0.969 in), a cross section of 3.6 mm (0.142 in), and an outside diameter of 31.8 mm (1.25 in), catalogued under part number V3.6X24.6. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against engine and transmission fluids, many acids, and aggressive chemicals. Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.
You will find this material specified across high-temperature process equipment, automotive fuel systems, and oil and gas.
V3.6X24.6 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
