INSTRUCTIONS FOR USE

For assembly as a form-in-place gasket 

1. Remove all previous material from mating surfaces. Permatex Gasket Remover or Silicone Stripper is recommended for most materials.

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

3. Cut nozzle to desired bead size, 1/16“ to 1/4“ in diameter. A 1/8” bead is usually sufficient for most applications.

4. Remove cap, puncture tube or cartridge seal and attach extension nozzle.

5. Apply a continuous and even bead of silicone to one surface, first tracing the internal areas of the gasket configuration, then all surrounding bolt holes as shown below: 

6. Assemble parts immediately while silicone is still wet. Secure or tighten to recommended torque specs.

7. Re-torque will not be necessary after the product has cured.
