-339 BLACK FKM 90D O-RING

APG stocks the V90339, an AS568-339 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 3.225 in (81.92 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.645 in (92.58 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. It resists chlorinated solvents, aggressive chemicals, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in aerospace, oil and gas, and chemical processing.

Stocked as V90339 and sold individually. Unit weight is approximately 11.292 g and nominal inside diameter is listed as 3 1/4 inch.
