-331 BROWN FKM 75D O-RING

VB75331 is an AS568-331 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 2.225 in (56.52 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.645 in (67.18 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is specified here for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. This material stands up to aromatic hydrocarbons, many acids, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

Common environments for this compound include high-temperature process equipment, chemical processing, and aerospace.

VB75331 ships individually. Unit weight is approximately 8.9905 g and nominal inside diameter is listed as 2 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
