Remflex exhaust gaskets are soft and compressible, so the recommended torque for any gasket that is usually much lower than factory torque is listed on the back of each package. Remflex is made in the USA to control every step of the manufacturing process and ensure a superior product you can rely on. Remflexs unique flexible graphite material has been proven for over 30 years in industrial applications where temperatures regularly exceed 2000 degrees, day after day, week and year after year. For over 10 years, Remflex has been bringing this technology to automotive enthusiasts of all kinds to eliminate exhaust leaks for good. Experience has shown that no seal should be reused if you want a reliable seal, so do not sell or marketed seals as reusable, although it has been said that they have been successfully reused in the past. Do not use any sealant with sealants. The sealant burns out quickly leaving a gap that creates an exhaust leak. Remflex exhaust gaskets are good up to 3000 degrees, which far exceeds the temperature rating of sealants.
