-274 BROWN FKM 90D O-RING

The VB90274 is an AS568-274 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 9.984 in (253.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.262 in (260.65 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or amines.

Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and automotive fuel systems.
