Pentair Cyclone jet socket
All Pentair Cyclone spa jets (like the Roto or the Diamond) fit into this socket. The jet socket is the fitting attached to the spa (inside and outside of the spa wall), which holds the jet in place. The fixing nut and the gasket are not included.
The flow of water through the socket sucks in air by the Venturi effect, thereby adding bubbles to your spa jet.
In order to manage the water and the air flow through the jets, the air nozzle is connected to a normal manifold et then on to a valve. If you do not want to have bubbles through the water jets, just close the air nozzle with a 3/8" plug.
