Enclosure Vent Documentation


The enclosure vent allows the release of trapped air when using the watertight enclosures. Once sealed, it provides a reliable high-pressure seal against water.

Important Notes

Always inspect the O-rings before inserting the plug. Any dust, hair, or other particles can cause a leak.

Use plastic tools, NOT steel or other hard tools, to remove the O-rings from the aluminum sealing flange. Hard tools can create scrapes that will compromise sealing ability.
