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, even bead of silicone to one surface, surrounding all bolt holes.
-
Assemble parts immediately while silicone is still wet. Finger tighten until material begins to squeeze out around flange.
-
Allow to dry for one hour then re-tighten 1/4 to 1/2 turn.
-
Silicone will skin over in one hour and fully cure in 24 hours under normal conditions.
-
Allow more time for cold or very dry conditions.
-
Clean uncured silicone from hands, tools and clothing with Permatex® Fast Orange® Wipes or Fast Orange® Hand Cleaner.
