3.5MM CS X 38.7MM ID BLACK FKM 75D

Part number V3.5X38.7 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 38.7 mm (1.524 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 45.7 mm (1.8 in). An o-ring compresses into its gland to block fluid or gas migration across a joint. Supplementary detail from the product record: Metric O-RING, JIS P39.

As a material, Viton® (FKM) delivers long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The material holds up against many acids, chlorinated solvents, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or low-molecular-weight organic acids will shorten service life.

Typical settings include aerospace, chemical processing, and automotive fuel systems.
