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.

If you’re looking for a complete underwater enclosure, check out the Watertight Enclosure Configuration page.

Please refer to the Technical Details section for actual inner diameter dimensions.
Because of the precision machined interface, the tubes are no longer available in custom lengths.

Product Description

These 2″, 3″, and 4″ locking tubes are available in a variety of lengths and in both cast acrylic plastic and anodized 6061-T6 aluminum. These tubes are a substantial upgrade over the first generation of watertight enclosure tubes.

Both the acrylic and aluminum tube options have precision machined O-ring interfaces at each end, ensuring a consistent and reliable fit with the sealing flange. A smooth surface finish ensures proper sealing between the O-ring flange and the tube. Also machined into the ends is a gland for a locking cord and a slot for cord insertion. You can read more about the locking feature and see a diagram of how it works on the main watertight enclosure product page.

The slot for cord insertion doubles as an anti-rotation feature, mating with a feature on the flange. This keeps the flange in a consistent orientation with the tube and prevents the user from rotating the flange and damaging anything inside the enclosure.

The tubes are available individually here, but you can configure a complete watertight enclosure from the watertight enclosure configuration page.

Because of the precision machined interface, the tubes are no longer available in custom lengths.
