Klingersil C-4401 is specified for reliable sealing on flanges with modest surface finish, consistent thickness and density across the sheet. It resists hydrocarbons, elevated flange loads, and a broad range of process chemicals. Exposure to strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope will shorten service life.

You will find this material specified across pulp and paper, power generation, and steam and hot water systems.

This item is sold individually under part number FLKCSC4401RF062A4. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
