APG stocks the V70237, an AS568-237 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 3.359 in (85.32 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.637 in (92.38 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The compound resists chlorinated solvents, engine and transmission fluids, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving low-molecular-weight organic acids or amines call for a different compound.
It sees regular use in aerospace, semiconductor equipment, and chemical processing.
Reference part number V70237 when ordering; the item is sold individually. Unit weight is approximately 5.072 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
