8.4MM CS X 244.5MM ID BLACK FKM 70D

Part number V8.4X244.5 is a black Viton® (FKM) 70 Shore A O-Ring built to an inside diameter of 244.5 mm (9.626 in), a cross section of 8.4 mm (0.331 in), and an outside diameter of 261.3 mm (10.29 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. The catalog record notes: Metric O-RING, JIS P245.

The material holds up against chlorinated solvents, many acids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.

You will find this material specified across chemical processing, automotive fuel systems, and aerospace.

Order part number V8.4X244.5, sold individually. 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.
