          Product Description

          Meet our second generation 2″ Series watertight enclosure for ROVs, AUVs, marine vehicles, and other harsh environments. It’s completely configurable with a variety of tube and end cap options offering a substantial upgrade over the first generation of watertight enclosures. Precision machined O-ring interfaces, a locking cord and anti-rotation feature to secure the flange, and smooth O-ring lead-in make these enclosures a perfect fit for a wide range of applications including MATE and Robosub ROVs, subsea batteries, cameras, electronics, data loggers, environmental monitoring, instrument housings, junction boxes, and more.

          When used with the clear acrylic plastic tube option, it’s easy to see the components inside the enclosure, ideal for subsea development projects and research ROVs and AUVs. The aluminum tube option provides a greater depth rating, opaque appearance, and better thermal transfer for high power applications like power supply housings and battery housings.

          Precision machined tube ends.

          Precision Machined O-ring Interface on the Tubes

          The acrylic tubes are cast optically clear material, like the previous generation, but the inner ends are now precision machined so that despite wide tolerances on the raw plastic material, the O-ring interface is always manufactured to tight tolerances. The aluminum tube options are also precision machined for an excellent fit. A smooth surface finish ensures proper sealing between the O-ring flange and the tube and a smooth O-ring lead-in shape makes it easy to insert the flange without damaging the O-rings.

          Because of the precision machined interface, the tubes are no longer available in custom lengths, however we have three different length options for the 2″ Series enclosures, representing the most popular lengths.

          Anti-Rotation Feature

          The tubes have a slot machined at each end that provides access to insert and remove the locking cord. That slot doubles as the mating point for a key that is machined into the flange. The key inserts into the slot so that the flange can only be installed in one orientation, preventing the end cap or flange from being rotated and damaging internal components.

          Locking Cord

          The locking cord is a reliable new feature in this generation of watertight enclosures. The locking cord allows you to secure the flange to the tube so that they cannot be separated unless the cord is removed. There’s a half-circle shape machined into the inside of the tube and a matching half-circle shape machined into the flange. Once assembled, a round plastic locking cord can be inserted into the circular space, preventing the flange from being removed from the tube.

          The locking cord is included with the enclosure and comes with a small anodized aluminum handle that can be attached to make the cord removal as easy as possible. On the contrary, if you want to make the enclosure tamper-resistant, you can cut off the cord and cover the insertion slot. This is suitable for finished products that are not intended to be opened by the user.

          Combined Flange Cap Design

          Exclusively for the new 2″ Series enclosure is a shift to combining the sealing flange and end cap into one part: the flange cap. While the flange seal is still available to handle the clear, dome, and custom end caps, the flange caps offer a combined solution that does not require any screws or assembly. There are zero, two, and four hole versions of the flange cap with threaded M10 holes to suit our cable penetrators.

          Configuring Your Enclosure

          The watertight enclosures are available through this configuration page, which lets you select a tube, flanges, end caps, vent, and more. You can also purchase components separately if you prefer.

          *If an end cap is selected, than an O-ring flange must be selected in the configurator. No flange will be selected for a flange cap option as the flange is already built in.
