M14 Vacuum Valve II 25624
One way vacuum valve, which uses the included hand pump to create a vacuum and activate the housing electronics, including the Vacuum Check light. These Vacuum Valves contain an integrated push button 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 press of a red button.
You must have the electronic circuitry installed in your housing for this system to work. The M14 size fits most smaller mirrorless housings and some others.
The basic valve uses a hand pump to create the vacuum.
All vacuum valves also include a hand pump and hand wrench tool for installing valves.
