3MM CS X 65MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A supplied with an inside diameter of 65 mm (2.559 in), a cross section of 3 mm (0.118 in), and an outside diameter of 71 mm (2.8 in), catalogued under part number V3X65. It remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to aromatic hydrocarbons, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or hot water and steam call for a different compound.

Maintenance and OEM teams specify it across chemical processing, high-temperature process equipment, and semiconductor equipment.

Order part number V3X65, sold individually. Unit weight is approximately 2.755 g. Check the compound against your process media, pressure and temperature before committing to a design.
