Product Description

When the end-caps and flanges are installed on our 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 our 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.
