2661/1661 Flexible Graphite Sheet (316SS Foil Insert)

Description and Applications
Style 2661/1661 flexible graphite sheet has pressure-temperature sealability capabilities that are far superior to all compressed fiber reinforced sheet materials. It is resistant to chemical attack by virtually all organic and inorganic fluids with the exception of concentrated, highly oxidizing acids. Gaskets cut from Style 2661/1661 flexible graphite sheet seal with low to moderate bolt loads and because of very low creep relaxation, re-torquing is rarely required. Flexible graphite conforms to irregular flange sealing surfaces and readily flows into flange irregularities enabling it to seal both smooth and coarse surface finishes.

Construction

Style 2661/1661 is a flexible graphite sheet reinforced with a 316SS foil, .002” thick. The flexible graphite sheet is made from exfoliated graphite flake which is compressed into foil by a carefully controlled calendaring process. In this process, the expanded flake particles are mechanically locked together without the use of fibers, binders or other additives. Sheets of graphite foil are then adhesive bonded and laminated to the required thickness with the 316SS foil core in the center.
