GASKET, KLNGR C4401, 2.500" 0.125 THK

APG stocks the 13850FF125B0250FC, a green Klingersil C-4401 Class 300/400/600 full face Flange Gasket built to a 2.5 inch nominal pipe size, a Class 300/400/600 pressure rating, and a thickness of 0.125 inch. A flange gasket seals a bolted flange connection across the full pressure rating of the class.

The material holds up against a broad range of process chemicals, elevated flange loads, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 is widely chosen for clean release and easy removal at teardown, 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.

You will find this material specified across refining, chemical processing, and power generation.

This item is sold individually under part number 13850FF125B0250FC. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
