Part number 13850RF125B0125FC is a green Klingersil C-4401 Class 300/400/600 ring face Flange Gasket supplied with a 1.25 inch nominal pipe size, a Class 300/400/600 pressure rating, and a thickness of 0.125 inch. A flange gasket provides a replaceable sealing element at every flanged pipe connection.
This material stands up to elevated flange loads, steam and hot water, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 is known for a calendered, compressed fiber structure bound with elastomer, excellent torque retention and low creep relaxation.
You will find this material specified across steam and hot water systems, power generation, and refining.
