Part number V90430 is an AS568-430 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 5.1 in (129.54 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.65 in (143.51 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) offers very low compression set at elevated temperature, excellent resistance to compression set and permeation. The material holds up against aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in ketones and esters or amines.

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

V90430 ships individually. Unit weight is approximately 30.409 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
