-417 BLACK FKM 90D O-RING

Ordered as V90417, this is an AS568-417 black Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to many acids, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.

Common environments for this compound include high-temperature process equipment, semiconductor equipment, and aerospace.

This item is sold individually under part number V90417. Nominal inside diameter is listed as 3 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
