1.78MM CS X 104.4MM ID BLACK FKM 75D

Part number V1.78X104.4 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 104.4 mm (4.11 in), a cross section of 1.78 mm (0.07 in), and an outside diameter of 107.96 mm (4.25 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is widely chosen for outstanding high-temperature capability and very low compression set at elevated temperature. The compound resists engine and transmission fluids, chlorinated solvents, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or low-molecular-weight organic acids call for a different compound.

You will find this material specified across semiconductor equipment, aerospace, and oil and gas.

Reference part number V1.78X104.4 when ordering; the item is sold individually. Unit weight is approximately 1.5875 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
