User:Dave3141592/Draft of Manifold (SCUBA)

In scuba diving equipment, a manifold is a type of diving cylinder valve which connects multiple cylinders together, allowing simultaneous access to their contents. In modern scuba diving, the term manifold usually refers specifically to the dual outlet isolation manifold.

Manifolded twin cylinders, consisting of two identical cylinders connected by a dual outlet isolation manifold, are the most commonly used configuration of twin cylinders, and are used as a form of redundancy.
