4MM CS X 200MM ID BLACK FKM 75D

Ordered as V4X200, this is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 200 mm (7.874 in), a cross section of 4 mm (0.157 in), and an outside diameter of 208 mm (8.19 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with hot water and steam or ketones and esters.

It sees regular use in oil and gas, chemical processing, and automotive fuel systems.
