Tubes for the 2″, 3″, and 4″ Series Watertight Enclosures, available in a variety of lengths and in clear cast acrylic plastic and aluminum materials. These are the second generation of these tubes with precision machined O-ring interfaces, a locking cord, and anti-rotation feature. Rated to depths up to 950 meters.
These tubes are not compatible with the first generation non-locking flanges.
Because of the precision machined interface, the tubes are no longer available in custom lengths.
