The VITON75205 is an AS568-205 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.421 in (10.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.699 in (17.75 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. This material stands up to engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. 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 ketones and esters or hot water and steam are present.
Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and automotive fuel systems.
Stocked as VITON75205 and sold individually. Unit weight is approximately 0.8168 g. 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.
