GASKET, KLNGR C4401, 12.00" 400# RF

The 13850RF062C1200FC is a green Klingersil C-4401 Class 400 ring face Flange Gasket with a 12 inch nominal pipe size, a Class 400 pressure rating, and a thickness of 0.062 inch. This flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Supplementary detail from the product record: NPS, 0.062 THK.

Expect good resistance to a broad range of process chemicals, elevated flange loads, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 delivers excellent torque retention and low creep relaxation, consistent thickness and density across the sheet. Verify compatibility before use with strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope.

Common environments for this compound include chemical processing, steam and hot water systems, and pulp and paper.
