3.5MM CS X 30.7MM ID BLACK FKM 75D

V3.5X30.7 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 30.7 mm (1.209 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 37.7 mm (1.48 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint. Additional detail on this item: Metric O-RING, JIS P31.

The material holds up against engine and transmission fluids, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or low-molecular-weight organic acids call for a different compound.

It sees regular use in semiconductor equipment, high-temperature process equipment, and oil and gas.
