As a material, Klingersil C-4401 is known for a calendered, compressed fiber structure bound with elastomer and reliable sealing on flanges with modest surface finish. The material holds up against elevated flange loads, steam and hot water, 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.

Common environments for this compound include refining, power generation, and steam and hot water systems.

Stocked as FLKC4401FF062B3.5 and sold individually. 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.
