Grafoil® flexible Graphite is one of our primary products. We have been providing die formed parts, and cut gaskets from Grafoil® since 1994.
Nothing seals as well as Grafoil®. It is a unique material in that it can diced into a 1000 peices and then formed into a single piece again. We offer the quality flexible graphite gasket material in sheet or cut gaskets too. If a refinery or chemical plant has a VOC leaks, chances are we are sealing it with flexible graphite. If you want to be assured of quality, specify Grafoil® . We’re finding better ways to serve our customers all the time. In addition to our expanding line of industrial seals, we’re updating our production capabilities and streamlining our process to provide you quality parts when you need them.
GRAFOIL® Flexible Graphite Seals & Gaskets
GRAFOIL flexible graphite, became a highly successful replacement for asbestos in high temperature sealing and chemical applications in the 1980’s.
Flexible graphites flexibility, resilience, and conformability enables AS&P to provide a variety of styles and products, providing our customers with individually designed flexible graphite based products and solutions for diverse applications in a wide range of industries. American Seal & Packing (AS&P) supplies GRAFOIL® Flexible Graphite in the following forms: Sheet, Braided, Die Formed, Cut Gaskets and Ribbon Pack and cord stock.
Ribbon Pack used for Valves in the field, or to make die formed packing sets is one of GRAFOIL® flexible Graphite’s most common uses. Used in Refineries, Power Plants, Chemical, Power Generation Facilities, or anyone dealing with high temp applications. Typically .015″ thick, it is wrapped around a valve stem until the OD required is achieved. In recent years many customers have converted over to our braided flexible graphite packing.
Flexible graphite Gasket Material, due to it’s softness seals great but can also break if bent too far. To make it easier to handle we offer it with a 316 S.S. foil insert, tanged insert, or for easier cutting – no insert at all. Available in a range of grades from automotive & Industrial to Nuclear.
Die formed sets for valves in applications that require the lowest of leak rates. This is a VOC solution. Now a standard in the valve industry because of it’s effectiveness, Graphite or carbon yarn end rings with die formed flexible graphite center rings.
Thermabriad Temp: 1200 F Steam, 0-14 pH
Thermabraid is the only braided flexible graphite packing made with genuine Grafoil flexible graphite. Like Ribbon Pack it can be used for Valves in the field, or to make die formed packing sets. GRAFOIL® flexible Graphite’s most common uses are in Refineries, Power Plants, Chemical, Power Generation Facilities, or anyone dealing with high temp applications.
What is the difference between Grafoil and generic flexible graphite?
There are two significant factors that affect the quality of flexible graphite. The purity of the graphite, and the method used to expand the graphite powder into flexible graphite. Generally, there are two acids used to cause the reaction that makes graphite pop like popcorn into the expanded worms flexible graphite is made from. Nucleic and Sulfuric acid do the job, but there is a difference. Sulfuric acid leaves over 400 ppm of sulfur in the material. Sulfur will cause pitting on 400-grade stainless steel damaging the surface you’re trying to seal. Sulfur is cheaper for the manufacturers to use, but due to the damage, it can cause, expensive for end-users to use.
