Where This Part Is Used

In typical pool and spa plumbing, the Air Control Knob Cap sits on air control assemblies that regulate airflow to spa jets and other air-intake components. It is commonly found on jet bodies and associated air control valves. The cap supports serviceability by providing a removable top when the control stem or cap wears. This accessory helps technicians maintain consistent air-to-water balance by protecting the control mechanism from debris and moisture. In many spa configurations, you’ll encounter it near the return lines and jet bodies where air control is integrated into the circulation loop.
