Ordered as V75MD109, this is an AS568-109 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 0.299 in (7.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.505 in (12.83 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

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

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include oil and gas, aerospace, and automotive fuel systems.

This item is sold individually under part number V75MD109. Nominal inside diameter is listed as 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
