Balboa Hydro Air Micro-ssage Jet

This is a thread-in style jet, so it is designed to screw directly into compatible Hydro-Air wall fittings. Before purchasing, ensure your current spa shell uses the standard Hydro-Air thread-in system, as it will not fit snap-in or clip-in style housings.

Yes, this is a complete assembly. It includes the jet insert, the flow path, and the threaded fitting, so you have all the necessary components to replace your old unit without needing extra parts.

You should measure the face of your current jet to ensure it matches the 3.56-inch diameter of this model. Additionally, check that your base diameter is approximately 2.44 inches to ensure a proper fit within the wall fitting.

This 'Roto' or rotating jet creates a spinning water stream that moves across your muscles, providing a kneading massage effect. A standard directional jet, by contrast, shoots a steady, stationary stream of water at one specific point.

Because this is sold as a complete assembly, it is designed to be replaced as a single unit. While it may be tempting to swap just the face, replacing the entire internal flow path ensures the best water pressure and prevents issues caused by worn-out internal seals.
