Balboa 1/2" Venturi Tee Nozzle (30-4308)

Restore the premium spa experience with the Balboa 1/2" Venturi Tee Nozzle (30-4308). Designed as a direct replacement for Balboa spa systems, this venturi nozzle preserves the essential air-and-water mixing action that powers your jets, delivering the bubbly, therapeutic flow you expect from a high‑quality hot tub.

Why this venturi nozzle matters

The venturi tee nozzle is the heart of many spa jets, controlling how air is entrained into the water stream to boost jet strength and bubble density. When a nozzle wears, cracks, or becomes misaligned, you’ll notice weaker jets and inconsistent therapy. This 1/2" nozzle ensures reliable venturi performance, maintaining steady flow and the invigorating sensation you rely on during your spa sessions.
