The silicone gasket is formed to size, eliminating any gaps or spaces which could cause leakage. Since it is the outer gasket, it provides protection for the EMI/RFI gasketing as well. As a bonus feature, the screws used to seal the box are fixed outside the enclosure interior, eliminating interference with the gasket and also providing additional space in the interior of the box. The box is submersible and is designed to meet IP67 ratings.
