-284 BLUE FKM 75D O-RING

Part number V75MD284 is an AS568-284 blue Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 17.955 in (456.06 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 18.233 in (463.12 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. The compound resists aromatic hydrocarbons, aggressive chemicals, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or low-molecular-weight organic acids are present.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across high-temperature process equipment, automotive fuel systems, and aerospace.

Stocked as V75MD284 and sold individually. Nominal inside diameter is listed as 18 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
