• Won’t Burn Out:
100% flexible graphite construction means Remflex gaskets are good for up to 3,000 degrees F—far exceeding that of any vehicle’s exhaust system temperature! 50% Crush
• No Re-Torquing Necessary:
Remflex exhaust gaskets rebound 30%, creating an optimum seal that eliminates the need to re-torque!
