How To Use

  1. For best results, clean and dry all surfaces with a residue-free solvent.
  2. Cut nozzle to desired bead size – gaskets are best formed using a 1/16" to 1/4" (2 to 6 mm) bead.
  3. 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 retighten 1/4 to 1/2 turn.
  4. Silicone dries in 1 hour, and fully cures in 24 hours. Allow more time in cold or very dry conditions.
  5. Replace cap after use. Clean hands with dry cloth or Permatex® Fast Orange® Hand Cleaner. Clean tools with nonflammable cleaning fluid.[/expand]
