-018 BROWN FKM 90D O-RING

VB90018 is an AS568-018 brown Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 0.739 in (18.77 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.879 in (22.33 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists aromatic hydrocarbons, chlorinated solvents, and many acids. Viton® (FKM) is known for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or ketones and esters are present.

Maintenance and OEM teams specify it across automotive fuel systems, aerospace, and high-temperature process equipment.

VB90018 ships individually. Unit weight is approximately 0.3596 g and nominal inside diameter is listed as 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
