GASKET, KLNGR C4401, 12.00" 300# FF

Ordered as 13850FF125B1200FC, this is a green Klingersil C-4401 Class 300 full face Flange Gasket built to a 12 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.125 inch. The flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Additional detail on this item: NPS, 0.125 THK.

Expect good resistance to steam and hot water, hydrocarbons, and a broad range of process chemicals. That behavior comes from the compound itself: Klingersil C-4401 is specified for reliable sealing on flanges with modest surface finish, consistent thickness and density across the sheet. It should not be specified for service in strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope.

Typical settings include steam and hot water systems, power generation, and refining.
