APG stocks the V75246, an AS568-246 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 4.484 in (113.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.762 in (120.95 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists chlorinated solvents, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound.
Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and oil and gas.
V75246 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
