2.5MM CS X 85MM ID BLACK FKM 75D

APG stocks the V2.5X85, a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 85 mm (3.346 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 90 mm (3.54 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.

Maintenance and OEM teams specify it across chemical processing, automotive fuel systems, and semiconductor equipment.

Stocked as V2.5X85 and sold individually. Unit weight is approximately 2.4964 g. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
