HydroAir extended wall fitting
This Balboa HydroAir extended wall fitting is well-suited to thick-walled spas (up to 50 mm), such as wooden hot tubs.
- A straight nut for 50 mm pipe
- A 90° nut for a 1.5-inch pipe
- A 90° nut for a 50 mm pipe
If your wall thickness is less than 35 mm, do not forget to add a nut with one of the adapters mentioned above. The female thread on the adapter is not long enough to crimp the part against the wall.
For shells that are less than 15 mm thick, use a short-threaded wall fitting instead.
Installation
You should install it with a gasket and also use silicone between the wall fitting and the interior wall of the spa.
