8.4MM CS X 299.5MM ID BLACK FKM 70D

Ordered as V8.4X299.5, this is a black Viton® (FKM) 70 Shore A O-Ring measuring an inside diameter of 299.5 mm (11.791 in), a cross section of 8.4 mm (0.331 in), and an outside diameter of 316.3 mm (12.45 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies. Additional detail on this item: Metric O-RING, JIS P300.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. This material stands up to petroleum oils and fuels, engine and transmission fluids, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

You will find this material specified across aerospace, high-temperature process equipment, and automotive fuel systems.

V8.4X299.5 ships individually. Unit weight is approximately 98.44 g. 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.
