V4.5X40 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 40 mm (1.575 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 49 mm (1.93 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is specified here for very low compression set at elevated temperature and industry benchmark where nitrile reaches its thermal limit. Expect good resistance to petroleum oils and fuels, aggressive chemicals, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

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