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. 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.

7. Finger tighten flange only until material begins to seep out the sides of the flange.

8. Allow to set for at least two hours and re-torque at least one quarter to one half turn.

9. For best results, allow to cure overnight.
