4" 300# FF .125" THK C4401

APG stocks the FLKC4401FF125B4, a Klingersil C-4401 Gasket Kit. A gasket kit packages the gaskets needed for a complete job so a crew can finish a turnaround without a second trip to the storeroom. This item is further identified as Stud Flange Kit.

Klingersil C-4401 is specified here for clean release and easy removal at teardown, reliable sealing on flanges with modest surface finish. Expect good resistance to a broad range of process chemicals, elevated flange loads, and hydrocarbons. It should not be specified for service in service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades.

You will find this material specified across chemical processing, refining, and power generation.
