Expect good resistance to petroleum oils and fuels, aggressive chemicals, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving amines or hot water and steam call for a different compound.

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

This item is sold individually under part number SV70379. Nominal inside diameter is listed as 11 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
