Q: How to apply

2 years ago
1 Answer
  • A: Hi James. DIRECTIONS FOR USE For assembly as a form-in-place gasket 1. Remove all previous material from mating surfaces. Permatex Gasket Remover is recommended for most materials, not for plastics or painted surfaces. 2. For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex Brake and Parts Cleaner. 3. Remove cap and puncture tube seal. 4. Apply a continuous and even bead of silicone (approximately 1/8” in diameter) to one surface, first tracing the internal areas of the gasket configuration, then all surrounding bolt holes as shown below: 5. Assemble parts immediately while silicone is still wet. 6. Secure or tighten to recommended torque specifications. Re-torque will not be necessary after the product has cured.
