3.5MM CS X 28MM ID BLACK FKM 75D

APG stocks the V3.5X28, a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 28 mm (1.102 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 35 mm (1.38 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists petroleum oils and fuels, engine and transmission fluids, and chlorinated solvents. Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.

You will find this material specified across chemical processing, semiconductor equipment, and aerospace.
