-138 BLACK FKM 90D O-RING

The V90138 is an AS568-138 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 2.112 in (53.64 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.318 in (58.88 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Viton® (FKM) is widely chosen for 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). Exposure to hot water and steam or ketones and esters will shorten service life.

It sees regular use in aerospace, high-temperature process equipment, and semiconductor equipment.

Stocked as V90138 and sold individually. Unit weight is approximately 1.7403 g and nominal inside diameter is listed as 2 1/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
