-918 BROWN FKM 90D O-RING

Part number VB90918 is an AS568-918 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 1.355 in (34.42 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.587 in (40.31 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against chlorinated solvents, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, very low compression set at elevated temperature. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or hot water and steam.

Common environments for this compound include oil and gas, automotive fuel systems, and chemical processing.

VB90918 ships individually. Unit weight is approximately 1.85 g and nominal inside diameter is listed as 1 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
