1.9MM CS X 5.7MM ID BLACK FKM 75D

The V1.9X5.7 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 5.7 mm (0.224 in), a cross section of 1.9 mm (0.075 in), and an outside diameter of 9.5 mm (0.37 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with ketones and esters or hot water and steam.

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