GASKET, KLNGR C4401, 8.000" 400# RF

Part number 13850RF062C0800FC is a green Klingersil C-4401 Class 400 ring face Flange Gasket with an 8 inch nominal pipe size, a Class 400 pressure rating, and a thickness of 0.062 inch. A flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Source specification: NPS, 0.062 THK.

It resists elevated flange loads, a broad range of process chemicals, and steam and hot water. That behavior comes from the compound itself: Klingersil C-4401 is widely chosen for consistent thickness and density across the sheet, excellent torque retention and low creep relaxation. Applications involving strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope call for a different compound.

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

13850RF062C0800FC ships individually. 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.
