  • Info
  • The Lungfish Gemini Dual Tank Valve is a switch block that allows an on-the-go switching between two input gases to a single output. Simply it allows plugging two separate gas cylinders into one primary regulator, facemask or diving helmet - thanks to the Lungfish Gemini Switch block, you can change your cylinders without taking the regulator out of your mouth. 

    The Lungfish Gemini Dual Tank Valve is supplied with a mounting block allowing the unit to be mounted vertically or horizontally directly onto your webbing or harness. It connects to standard regulator hoses.

    The Lungfish Gemini switch block is a beautiful piece of precision engineering made out of marine grade brass for durability and oxygen ready straight from the factory.
