3MM CS X 107MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A measuring an inside diameter of 107 mm (4.213 in), a cross section of 3 mm (0.118 in), and an outside diameter of 113 mm (4.45 in), catalogued under part number V3X107. It remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to engine and transmission fluids, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or hot water and steam are present.

It sees regular use in semiconductor equipment, aerospace, and automotive fuel systems.

This item is sold individually under part number V3X107. Unit weight is approximately 4.495 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
