2.5MM CS X 70MM ID BLACK FKM 75D

Part number V2.5X70 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 70 mm (2.756 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 75 mm (2.95 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where amines or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across high-temperature process equipment, oil and gas, and automotive fuel systems.
