The V3X78 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 78 mm (3.071 in), a cross section of 3 mm (0.118 in), and an outside diameter of 84 mm (3.31 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.
Viton® (FKM) is widely chosen for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. It resists engine and transmission fluids, many acids, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.
Common environments for this compound include semiconductor equipment, high-temperature process equipment, and aerospace.
Order part number V3X78, sold individually. Unit weight is approximately 3.2724 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
