Waterway 1″ Notched Air Control [1-5/8″ HS, 2-3/4″ FD] [Grey] (660-3577)

Description

The Waterway 660-3577 notched air control is designed for compatible spa air systems and uses a 1-5/8 inch hole size with a 2-3/4 inch face diameter in grey. This type of control helps regulate the air introduced into the spa system, which can influence how the jets feel and how the overall hydrotherapy experience is tuned.

The grey finish makes it a strong match for spas with cooler-toned shells or trim, and the notched design supports compatibility in installations that call for that specific control format. When the original control becomes worn, difficult to turn, or visually tired, this Waterway replacement can help restore a more refined and functional result.

For spa repairs and control-area refresh projects, this Waterway air control offers a dependable way to bring back adjustable airflow and a better finished appearance.
