Watertight Enclosure End Caps, Domes, and Flange Caps
$14.00 – $52.00
End caps and flange caps for the 2″, 3″, and 4″ Series Watertight Enclosures. These are the second generation of these end caps and flange caps with precision machined O-ring interfaces, a locking cord, anti-rotation feature, and optional M10 holes for cable penetrators. Rated to depths up to 950 meters.
A variety of end cap and flange cap options for the 2″, 3″, or 4″ Series Watertight Enclosures allow you to customize your enclosure for your application. End caps require an O-ring sealing flange to be installed on the enclosure and flange caps have the O-ring sealing flange built-in so that one is not necessary.
The clear acrylic end cap and dome end cap offer optically clear ports for cameras, lights, and other applications where optical clarity is important. They install to the O-ring sealing flange with six included screws.
The flange caps are anodized aluminum and include the same features as the O-ring sealing flange including dual radial O-rings for reliable high-pressure sealing, a locking cord gland, and an anti-rotation feature. The flange caps are available with a solid blank end, which can be machined with custom hole patterns, as well as M10 threaded holes for our cable penetrators. The flange caps do not require any screws, eliminating the need for stainless steel near the enclosures and preventing galvanic corrosion.
The end caps and flange caps are available individually here, but you can configure a complete watertight enclosure from the watertight enclosure configuration page.
Tube and flange with the locking cord installed.
