Installation Instructions

Clean the mounting surface, ensuring it is free of oil, dust, and moisture.

Select a gasket with the appropriate diameter and thickness.

Remove the protective film from the adhesive backing.

Apply the gasket to the mounting location and press down evenly.

Allow the assembly to sit for 24 hours before performing any stress or load testing.

Precautions

⚠️ Ensure the surface is clean and dry before installation to guarantee optimal adhesion.

⚠️ Expanded silicone has a high compression ratio; please select the appropriate thickness based on the width of the gap.

⚠️ Avoid prolonged exposure to strong acids, strong bases, or oils.

⚠️ Adhesive strength may decrease in low-temperature environments; installation at room temperature is recommended.

⚠️ Please contact customer service for custom sizes or shapes.
