Model I Flange Sight Glass with Teflon® Insert

The Model I Flange with Teflon® insert mounts on standard ANSI B16.5 (2" thru 8") flange connections. It is designed to be used when the wetted part (insert) needs to be made of Teflon®. The Model I Flange uses a threaded cap that allows you to change outspare parts without disturbing the Teflon® insert bolted between flanges. This unit is rated for temperatures up to 450°F, and uses Teflon® packing and gaskets. Applications requiring DIN standards or non-ANSI flanges are available upon request and no mating gasket required.
