The 7/16-inch female end screws into a mini-SPG, and the other end of the adapter is an airspool that connects to a high-pressure hose. Another popular application for this adapter is to solve an often seen problem with the remote pressure transmitter on air integrated dive computers. Screwing the transmitter directly in to a HP port can obstruct access to an adjacent port on some first stage designs. This adapter can be used as a 'standoff', raising the transmitter away from the body of the first stage. Made of chrome plated brass and is Nitrox Ready.
