Applications involving ketones and esters or hot water and steam call for a different compound.

Common environments for this compound include high-temperature process equipment, chemical processing, and oil and gas.

Stocked as SV70177 and sold individually. Nominal inside diameter is listed as 9 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
