6" 300# FF .062" THK C4401

Ordered as FLKC4401FF062B6, this is a Klingersil C-4401 Gasket Kit. The gasket kit simplifies ordering and reduces the chance of a missing item at assembly. This item is further identified as Stud Flange Kit.

This material stands up to steam and hot water, elevated flange loads, and hydrocarbons. That behavior comes from the compound itself: Klingersil C-4401 is specified for consistent thickness and density across the sheet, excellent torque retention and low creep relaxation. Applications involving strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope call for a different compound.

It sees regular use in chemical processing, power generation, and pulp and paper.
