-408 BROWN FKM 75D O-RING

Part number VB75408 is an AS568-408 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 2.35 in (59.69 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.9 in (73.66 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to engine and transmission fluids, aggressive chemicals, and chlorinated solvents. Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

It sees regular use in aerospace, chemical processing, and automotive fuel systems.

VB75408 ships individually. Nominal inside diameter is listed as 2 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
