3MM CS X 8.5MM ID BLACK FKM 75D

APG stocks the V3X8.5, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 8.5 mm (0.335 in), a cross section of 3 mm (0.118 in), and an outside diameter of 14.5 mm (0.57 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is known for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. It resists many acids, engine and transmission fluids, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

Common environments for this compound include chemical processing, aerospace, and semiconductor equipment.
