Product Specification

-
APG stocks the 13850FF125B2000FC, a green Klingersil C-4401 Class 300 full face Flange Gasket supplied with a 20 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.125 inch. A flange gasket seals a bolted flange connection across the full pressure rating of the class. This item is further identified as NPS, 0.125 THK.

Klingersil C-4401 is valued for consistent thickness and density across the sheet, a calendered, compressed fiber structure bound with elastomer. This material stands up to steam and hot water, hydrocarbons, and elevated flange loads. It is not the right choice where strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope are present.

Common environments for this compound include power generation, refining, and pulp and paper.

13850FF125B2000FC ships individually. Review your operating media and conditions against this specification before installation.
