-218 BLACK FKM 90D O-RING

This o-ring is supplied in AS568-218 black Viton® (FKM) 90 Shore A supplied with an inside diameter of 1.234 in (31.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.512 in (38.4 mm), catalogued under part number V90218. It compresses into its gland to block fluid or gas migration across a joint.

The material holds up against engine and transmission fluids, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or amines.

Maintenance and OEM teams specify it across chemical processing, oil and gas, and automotive fuel systems.

This item is sold individually under part number V90218. Unit weight is approximately 1.9999 g and nominal inside diameter is listed as 1 1/4 inch.
