Product description                                     

FST G-Spezial I is made of temperature resistant, flexible braided graphite yarns each of which is reinforced with a very thin Inconel wire. The packing  is additionally treated with a corrosion inhibitor.

This highly pressure-resistant braided packing has the same excellent sealing effect as pure graphite rings wound from strip material and has the added advantage for variable use in the area of repair and service.

FST G-Spezial I has a fire test approval according to API 589 Rev. 2. For gaps greater than 0,2 mm, the use of FST Carbosteam 6550 as ex trusion protection is recommended.
