3MM CS X 55MM ID BLACK FKM 75D

The V3X55 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 55 mm (2.165 in), a cross section of 3 mm (0.118 in), and an outside diameter of 61 mm (2.4 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The material holds up against petroleum oils and fuels, chlorinated solvents, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

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