Product Specification

-
This flange gasket is supplied in green Klingersil C-4401 Class 300 full face built to a 4 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.125 inch, catalogued under part number 13850FF125B0400FC. It provides a replaceable sealing element at every flanged pipe connection. Source specification: NPS, 0.125 THK.

Expect good resistance to steam and hot water, a broad range of process chemicals, and hydrocarbons. Klingersil C-4401 offers excellent torque retention and low creep relaxation, a calendered, compressed fiber structure bound with elastomer. Verify compatibility before use with service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades.

Common environments for this compound include refining, chemical processing, and pulp and paper.

This item is sold individually under part number 13850FF125B0400FC. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
