8.4MM CS X 214.5MM ID BLACK FKM 70D

Ordered as V8.4X214.5, this is a black Viton® (FKM) 70 Shore A O-Ring measuring an inside diameter of 214.5 mm (8.445 in), a cross section of 8.4 mm (0.331 in), and an outside diameter of 231.3 mm (9.11 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Additional detail on this item: Metric O-RING, JIS P215.

It resists engine and transmission fluids, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

You will find this material specified across high-temperature process equipment, oil and gas, and aerospace.

V8.4X214.5 ships individually. Unit weight is approximately 70.787 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
