-118 BLACK CHEMOURS VITON 75D O-RING

This o-ring is supplied in AS568-118 black Viton® (FKM) 75 Shore A built to an inside diameter of 0.862 in (21.89 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.068 in (27.13 mm), catalogued under part number VITON75118. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists aromatic hydrocarbons, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers outstanding high-temperature capability and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving amines or ketones and esters call for a different compound.

Common environments for this compound include semiconductor equipment, chemical processing, and aerospace.

Stocked as VITON75118 and sold individually. Unit weight is approximately 0.7708 g and nominal inside diameter is listed as 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
