V75042 is an AS568-042 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 3.239 in (82.27 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.379 in (85.83 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. This material stands up to chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.
It sees regular use in semiconductor equipment, automotive fuel systems, and oil and gas.
Stocked as V75042 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
