-170 BROWN FKM 90D O-RING

Ordered as VB90170, this is an AS568-170 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to aggressive chemicals, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving ketones and esters or amines call for a different compound.

You will find this material specified across oil and gas, chemical processing, and high-temperature process equipment.

VB90170 ships individually. Nominal inside diameter is listed as 7 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
