1" Air Control Diaphragm – 662-2140 Replacement

Restore smooth, responsive air flow to your spa’s jet system with the 662-2140 Air Control Diaphragm (1"), designed for reliable replacement in standard 1" air control valves. This flexible diaphragm regulates the amount of air drawn into your jets, helping maintain strong, balanced water-air mixing for consistent hydrotherapy performance.

If your air control is sticking, making noise, leaking air, or failing to adjust properly, a worn diaphragm is often the cause. Replacing it restores proper valve operation without requiring a full valve replacement. Built from durable, spa-rated materials, this diaphragm resists chemical exposure, heat, and long-term water contact.

Perfect for spa repairs, valve maintenance, and restoring strong jet action.
