VACUUM VALVE FOR M14 HOLES

This Vacuum Valve for M14 Accessory Port from Ikelite is for use with Nauticam, Isotta, Nimar, or any other brand's housing with an M14-threaded accessory port. Its low profile keeps it out of the way, and the waterproof plug is tethered to prevent loss. It is installed by securing one nut on the inside of the housing.
