GASKET, KLNGR C4401, 20.00" 300# RF

13850RF125B2000FC is a green Klingersil C-4401 Class 300 ring face Flange Gasket measuring a 20 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.125 inch. In service, this flange gasket provides a replaceable sealing element at every flanged pipe connection. Source specification: NPS, 0.125 THK.

This material stands up to a broad range of process chemicals, elevated flange loads, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 delivers consistent thickness and density across the sheet, reliable sealing on flanges with modest surface finish. It is not the right choice where strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope are present.

Maintenance and OEM teams specify it across refining, pulp and paper, and steam and hot water systems.

13850RF125B2000FC ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
