DIRECTIONS:

  1. For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex® Brake & Parts Cleaner.

  2. Cut nozzle to desired bead size – gaskets are best formed using a 1/16" to 1/4" (2-6mm) 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 non-flammable cleaning fluid.

NOTE: Not recommended for use on head gaskets or parts in contact with gasoline.

NOTE: Due to warranty issues, technology changes (i.e. sensors, etc.), aluminum components, Part No. 27BR can be replaced with ULTRA COPPER®, Part No. 81878 for optimal sealing performance.
