This quad-ring is supplied in AS568-369 black Viton® (FKM) 70 Shore A square profile measuring an inside diameter of 7.975 in (202.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.395 in (213.23 mm), catalogued under part number SV70369. It delivers lower friction and better sealing stability than a comparable round-section o-ring.
The compound resists aromatic hydrocarbons, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life.
It sees regular use in chemical processing, oil and gas, and automotive fuel systems.
Reference part number SV70369 when ordering; the item is sold individually. Nominal inside diameter is listed as 8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
