HydroAir Jet Manifold Body 50-9072 Air Water Venturi 50972 Hydro Air Message Jet

This item is a single complete jet body venturi assembly. It contains the venturi jet, retaining rings and a smart water back-up prevention device. There is a small "ball" that when the air pressure is either off or low any water that makes its way up to the air induction port pushes the ball into the slot and helps prevent the water from getting into the air lines.

Please independently verify compatibility for usage prior to purchasing.
