V70343 is an AS568-343 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 3.725 in (94.62 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.145 in (105.28 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Viton® (FKM) is known for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. The compound resists aromatic hydrocarbons, many acids, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.
Typical settings include aerospace, semiconductor equipment, and high-temperature process equipment.
V70343 ships individually. Unit weight is approximately 12.859 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
