This o-ring is supplied in AS568-211 blue Viton® (FKM) 75 Shore A built to an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm), catalogued under part number V75MD211. It creates a positive seal at flange, piston and rod interfaces without added hardware.
This material stands up to aromatic hydrocarbons, engine and transmission fluids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.
This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across aerospace, semiconductor equipment, and oil and gas.
V75MD211 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
