APG stocks the FLKC4401FF125A6, a Klingersil C-4401 Gasket Kit. A gasket kit simplifies ordering and reduces the chance of a missing item at assembly. This item is further identified as Stud Flange Kit.

As a material, Klingersil C-4401 is known for a calendered, compressed fiber structure bound with elastomer, excellent torque retention and low creep relaxation. It resists a broad range of process chemicals, steam and hot water, and hydrocarbons. It should not be specified for service in service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades.

Maintenance and OEM teams specify it across chemical processing, refining, and power generation.
