1.9MM CS X 4.9MM ID BLACK FKM 75D

V1.9X4.9 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 4.9 mm (0.193 in), a cross section of 1.9 mm (0.075 in), and an outside diameter of 8.7 mm (0.34 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) is widely chosen for very low compression set at elevated temperature, excellent resistance to compression set and permeation. The compound resists aggressive chemicals, petroleum oils and fuels, and chlorinated solvents. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

You will find this material specified across aerospace, semiconductor equipment, and oil and gas.
