8.4MM CS X 294.5MM ID BLACK FKM 70D

Ordered as V8.4X294.5, this is a black Viton® (FKM) 70 Shore A O-Ring with an inside diameter of 294.5 mm (11.594 in), a cross section of 8.4 mm (0.331 in), and an outside diameter of 311.3 mm (12.26 in). The o-ring compresses into its gland to block fluid or gas migration across a joint. Source specification: Metric O-RING, JIS P295.

Viton® (FKM) is specified here for very low compression set at elevated temperature and industry benchmark where nitrile reaches its thermal limit. Expect good resistance to aggressive chemicals, petroleum oils and fuels, and engine and transmission fluids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

Common environments for this compound include oil and gas, automotive fuel systems, and aerospace.
