3.1MM CS X 104.4MM ID BLACK FKM 75D

V3.1X104.4 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 104.4 mm (4.11 in), a cross section of 3.1 mm (0.122 in), and an outside diameter of 110.6 mm (4.35 in). In service, this 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 G105.

Expect good resistance to aggressive chemicals, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or ketones and esters.

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and semiconductor equipment.
