GASKET, KLNGR C4401, 10.00", 300# RF

13850RF062B1000FC is a green Klingersil C-4401 Class 300 ring face Flange Gasket built to a 10 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.062 inch. In service, this flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Source specification: NPS, 0.062 THK.

The material holds up against a broad range of process chemicals, elevated flange loads, and steam and hot water. Klingersil C-4401 is known for consistent thickness and density across the sheet, excellent torque retention and low creep relaxation. Verify compatibility before use with service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades.

Maintenance and OEM teams specify it across power generation, steam and hot water systems, and refining.

13850RF062B1000FC 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.
