4MM CS X 55MM ID BLACK FKM 75D

APG stocks the V4X55, a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 55 mm (2.165 in), a cross section of 4 mm (0.157 in), and an outside diameter of 63 mm (2.48 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to aggressive chemicals, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or ketones and esters.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and chemical processing.
