Graphite was one of the forerunners in the battle to replace Asbestos for safety reasons. Known as the “DRY LUBRICANT” the solid material is the only non metal conductor of electricity. A natural product mined mainly in China and Mongolia it is a soft product mined in various sizes of flakes depending on application. It acts as a lubricant and can operate in temperatures up 750 degrees celsius. Our comprehensive range of graphite products, including graphite gaskets, graphite seals and graphite O-rings, consists of pure unreinforced sheet and tape, self adhesive tape and then laminated in either a foil or tanged form with a core of various grades of stainless steel including 316 and 304. Also Nickle Duplex and Super duplex.
Graphite gaskets are well suited to processes that demand high‐performance at increased temperatures and pressures. In addition, there are several properties which make graphite suitable for high‐performance gaskets.
Graphite gaskets have become popular in many industries because of the advantages they have over other materials that were previously used in their place. As a result today graphite gaskets have almost replaced other alternatives for example iron, asbestos and metal.
Graphite gaskets are used in processes that include corrosive media. For example ammonia, hot water, high pressure vapours, ultra‐cool liquids and hydrocarbons. As a result this makes them the top choice for heat exchangers, cooling towers and high pressure pipes.
