Nauticam M16 Offset Extension with Vacuum Valve (Pushbutton Release).
Offset Extension Valves are used when a housing has a single accessory
hole, but requires both a Vacuum Valve and electrical bulkhead to be
installed in the same location. This will enable most housings to be
able to utilize this valuable tool.
This is a one way vacuum valve, which is available in several styles to
support various housing configurations. These Vacuum Valves contain an
integrated vacuum release, and a redundant waterproof cap. No tools are
required to open the housing after creating a vacuum, as the vacuum is
released with a simple knurled nut.
Mounting the vacuum valve on these Nauticam housings will require the M14 Extension for M14 Vacuum Valve.
Seacam and Subal housings will also require the extension.
