Vent for WTC

Write a Review

This vent allows trapped pressure to escape from an enclosure after it has been closed. Based on the cable penetrator design, it includes a threaded plug with double O-ring seal to open and close the vent.

When the end-caps and flanges are installed on watertight enclosures, the air inside is compressed a bit and tries to push the enclosure open. This vent allows you to quickly and easily release the pressure and then seal things back up. It’s based on a cable penetrator design with an added “plug” that fits in to seal it. The plug is sealed with double O-rings and secured with screw threading.
