QV70226 is an AS568-226 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 1.984 in (50.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.262 in (57.45 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.
As a material, Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. This material stands up to petroleum oils and fuels, aromatic hydrocarbons, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.
You will find this material specified across oil and gas, chemical processing, and automotive fuel systems.
Reference part number QV70226 when ordering; the item is sold individually. Unit weight is approximately 3.09 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
