The flange gasket provides a replaceable sealing element at every flanged pipe connection. Supplementary detail from the product record: NPS, 0.062 THK.

Expect good resistance to elevated flange loads, steam and hot water, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 offers reliable sealing on flanges with modest surface finish, excellent torque retention and low creep relaxation.

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