Diving mask seals are typically made from soft, flexible materials such as high-grade silicone or rubber. These materials have good corrosion resistance, wear resistance and cold resistance, and can maintain sealing performance under different water temperatures and environmental conditions.
Adhesive seal: This seal is attached to the edge of the mask with a special adhesive or glue to form a continuous sealing ring. It generally provides a good seal and comfort, but may need to be replaced or re-glued periodically to maintain a good seal.
Dual Seal Design: Some diving masks feature a dual seal design, which means two seals are installed on the mask at the same time. This design can provide more reliable sealing performance, even if one of the seals is damaged or fails, the other seal can still maintain the seal. Dual-seal designs are commonly used on some professional-grade diving masks.
