Expect good resistance to steam and hot water, elevated flange loads, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 offers a calendered, compressed fiber structure bound with elastomer, consistent thickness and density across the sheet. It should not be specified for service in strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope.

Typical settings include refining, chemical processing, and power generation.

This item is sold individually under part number 13850RF125A0300FC. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
