4 Port 25mm Air Manifold – Spa Pool Plumbing Air Venturi System

High-quality 4 Port 25mm Air Manifold designed specifically for spa pool plumbing, air venturi systems, and spa jet air distribution. Ideal for supplying consistent airflow to multiple spa jets, this manifold helps maximise jet performance, aeration, and massage pressure in spa pools and hot tubs.
