GASKET, KLNGR C4433, 4.000 , 150# RF

13C4433RF062A0400 is a red Klingersil C-4433 Class 150 ring face Flange Gasket built to a 4 inch nominal pipe size, a Class 150 pressure rating, and a thickness of 0.062 inch. In service, this flange gasket seals a bolted flange connection across the full pressure rating of the class. Source specification: NPS, 0.062 THK.

The compound resists hydrocarbons, steam and hot water, and elevated flange loads. That behavior comes from the compound itself: Klingersil C-4433 is valued for excellent torque retention and low creep relaxation, consistent thickness and density across the sheet. It is not the right choice where service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades are present.

It sees regular use in steam and hot water systems, power generation, and refining.
