Die Formed Flexible Graphite

Formed Flexible Graphite is an art. It's also proven to be the solution to keeping VOC levels on Valves and pumps to an acceptable level. What begins as Ribbon Pack, becomes custom shaped parts. With the addition of metal end caps or braided packing, flexible graphite can be made to resist extrusion and maintain a seal better than any other fluid sealing product.

Flexible Graphite

Flexible Graphite

Graphite Comes in many forms including sheet, cut gaskets and die formed rings. It is formed into specifc shapes including cone, square round and rectangular, to seal valves or pumps from leakage. It starts as a sheet which is then either cut into gaskets or stipped so it can be wound into a die for forming.

Crinkel Pack Ribbon

Ribbon Pack®Is a registered trademark of Graftech. Flexible graphite stripped and crinkeled allows the graphite to be wrapped around a stem, shaft or sleeve without cracking.

Crinkeled flexible graphite is used for Valves in the field, or to make die formed packing sets. Themost common industries that rely on this form of flexible graphite include:. Refineries,Solar Power Plants, Steam Co_Generation, Nuclear, Fossil Fuel, Chemical, Aerospace, Etc. Ideal for Chemical and high temperature applications.
Die Formed Graphite
Once the Flexible graphite has been slit, crinkeled and wrapped around the die mandrel, it is compressed with the mating die to form a ring.


Die Formed Cup and Cone design.Often provides the lowest of leak rates. Now a standard in the valve industry. Combination sets with Peek or altering Density rings are solving API leakage requirments.Die formed flexible graphite center rings


Flexible graphite can extrude.having the advantage of high conformity also has the disadvantage of being soft enough to be pushed out under high pressure.The solution to this enharent problem is the addition of Stianless Steel or Inconel Wire. Various percentages of
