GASKET, KLNGR C4430, 3.000" 150# RF

13C4430RF125A0300 is a green Klingersil C-4430 Class 150 ring face Flange Gasket with a 3 inch nominal pipe size, a Class 150 pressure rating, and a thickness of 0.125 inch. In service, this flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. The catalog record notes: NPS,0.125 THK.

It resists elevated flange loads, hydrocarbons, and steam and hot water. Klingersil C-4430 is valued for excellent torque retention and low creep relaxation, clean release and easy removal at teardown. It is not the right choice where service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades are present.

Maintenance and OEM teams specify it across pulp and paper, power generation, and refining.
