3.53MM CS X 68.26MM ID BLACK FKM 75D

The V3.53X68.26 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 68.26 mm (2.687 in), a cross section of 3.53 mm (0.139 in), and an outside diameter of 75.32 mm (2.97 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to many acids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

Typical settings include semiconductor equipment, aerospace, and chemical processing.

Order part number V3.53X68.26, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
