3. Setup and Preparation

Proper surface preparation is crucial for optimal adhesion and sealing performance.

1. For best results, ensure all surfaces to be sealed are clean and dry. Remove any old gasket material, grease, oil, or other contaminants.
2. Prepare the tube by cutting the nozzle to the desired bead size. A typical bead size is 1/16 inch to 1/4 inch (2 to 6mm).

4. Operating Instructions (Application)

Follow these steps for effective application of the gasket maker:

1. Apply a continuous, even bead of 1/16 inch to 1/4 inch (2 to 6mm) to one surface, surrounding all bolt holes.
2. Assemble parts immediately while the silicone is still wet. Finger tighten until the material begins to squeeze out around the flange.

Important Notes:

• Do not use on head gaskets or in parts that will come into contact with gasoline.

5. Curing and Post-Application

Proper curing ensures the gasket maker achieves its full strength and sealing capabilities.

1. Allow the assembly to dry for one hour, then tighten to the manufacturer's specified torque.
2. Allow 24 hours for the gasket maker to fully cure before filling with fluids or returning the component to service.

6. Maintenance

To ensure the longevity of the product and its effectiveness for future use:

• Replace the cap after each use to prevent the product from drying out.
• Store the tube in a cool, dry, and well-ventilated area, away from direct sunlight.

7. Troubleshooting

If the gasket maker does not perform as expected, consider the following:

• Poor Adhesion: Ensure surfaces were thoroughly cleaned and dried before application. Any oil, grease, or old gasket residue can prevent proper bonding.
• Leaking: Verify that the bead applied was continuous and of adequate thickness (1/16" to 1/4"). Ensure sufficient cure time (24 hours) was allowed before exposing the seal to fluids or stress. Check if the parts were assembled immediately while the silicone was still wet.
• Incomplete Cure: Ensure the product was not used in an application involving gasoline contact, as this can inhibit curing. Verify that the product was stored correctly and has not expired.
