-351 BLACK CHEMOURS VITON 75D O-RING

This o-ring is supplied in AS568-351 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm), catalogued under part number VITON75351. It remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The material holds up against many acids, chlorinated solvents, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or ketones and esters will shorten service life.

You will find this material specified across high-temperature process equipment, aerospace, and semiconductor equipment.

VITON75351 ships individually. Unit weight is approximately 16.297 g and nominal inside diameter is listed as 4 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
