Remflex DIY Gasket Sheet material is an outstanding high temperature material. In addition to high temperatures, it is also resistant to oils, solvents and chemicals. Its uses are limited only by your imagination and fabrication skills. With this in mind however, the customer is still responsible for all engineering in regards to qualifying the functionality of Remflex Gasket Material Sheets used in their particular application. Remflex DIY Material is soft and compressible therefore it requires less torque than other materials to seat properly. Please use care when tightening down. The material can crush down to 1/16" thick but will normally seal long before that. If this material is over-torqued you can crack it and create a leak. Remflex's unique flexible graphite material has been proven for more than 30 years in industrial applications, where temperatures routinely exceed 2,000 degrees-day after day, week after week, year after year. For over 10 years we have been bringing this technology to automotive enthusiasts of all kinds to eliminate exhaust leaks for good!.
