DIRECTIONS:
-
For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex® Brake & Parts Cleaner.
-
Cut nozzle to desired bead size– gaskets are best formed using a 1/16" to 1/4" (2 to 6 mm) bead.
-
Apply a continuous and even bead of silicone to one surface; surround all bolt holes. Assemble parts immediately.
-
Finger tighten bolts until material begins to squeeze out around flange
-
Allow to dry for one hour then re-tighten 1/4 to 1/2 turn.
-
Silicone dries in 1 hour, and fully cures in 24 hours. Allow more time in cold or very dry conditions.
-
Replace cap after use.
-
Clean hands with dry cloth or Permatex® Fast Orange® Hand Cleaner. Clean tools with non-flammable cleaning fluid.
