Directions for Use:

  1. Surface Preparation: Clean all surfaces thoroughly, remove old gaskets, and prepare the flange surface by drying and removing any oil and grease.
  2. Application: Remove the cap, puncture the inner seal, screw on the nozzle, and cut it to your desired size.
  3. Applying the Sealant: Apply a continuous, uniform bead (1/16″ to 1/8″) around the perimeter of one surface, ensuring complete coverage around all bolt holes.
  4. Skin Over: Wait for 10 minutes for the silicone to skin over before reassembling the parts.


  • Avoid contact with eyes and skin as uncured sealant can cause irritation. In case of contact with eyes, flush with water and seek medical attention. Remove from the skin with a dry cloth or paper towel.
  • The sealant releases acetic acid (vinegar-like odor) during curing, so use it with adequate ventilation and keep it out of the reach of children.

Additional Tips:

  • Leave the appropriate thickness for the gasket when reassembling parts.
  • Do not over-tighten bolts, and remove excess silicone with a dry cloth or alcohol wipe.
  • The silicone dries to the touch in 1 hour, but allow 24 hours for it to fully cure and bond. Always replace the cap after use.
