-400 BLACK FKM 90D O-RING

The V90400 is an AS568-400 black Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 1.35 in (34.29 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 1.9 in (48.26 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to chlorinated solvents, many acids, and aromatic hydrocarbons. Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across semiconductor equipment, chemical processing, and high-temperature process equipment.
