The O-ring Flange seals to a tube on one end and to an end cap on the other. These are used with our flat end caps and dome end caps to create a high-pressure watertight interface to the enclosure tube. The flange can be used with custom made end caps as well.

These second generation flanges are anodized aluminum and include dual radial O-rings and a face seal O-ring for reliable high-pressure sealing, a locking cord gland, and an anti-rotation feature. They comes with PTFE locking cord and locking cord handles to secure the flange to the tube. These flanges are only compatible with our watertight enclosure tubes, which have precision machined features at each end to interface with the flange.

Four internal mounting holes make it easy to attach internal contents securely. This feature is used on the BlueROV2 to hold the electronics tray.

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