GASKET, KLNGR C4401, 4.500", 300# RF

13850RF062B0450 is a green Klingersil C-4401 Class 300 ring face Flange Gasket with a 4.5 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.062 inch. In service, this flange gasket compresses between two pipe flanges under bolt load to create a leak-tight joint. Supplementary detail from the product record: NPS, 0.062 THK.

Klingersil C-4401 is specified here for excellent torque retention and low creep relaxation, reliable sealing on flanges with modest surface finish. It resists elevated flange loads, steam and hot water, and a broad range of process chemicals. It is not the right choice where service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades are present.

You will find this material specified across chemical processing, pulp and paper, and steam and hot water systems.
