2MM CS X 8.5MM ID BLACK FKM 75D

V2X8.5 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 8.5 mm (0.335 in), a cross section of 2 mm (0.079 in), and an outside diameter of 12.5 mm (0.49 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists aggressive chemicals, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

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

V2X8.5 ships individually. Unit weight is approximately 0.1913 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
