On/Off Controls

On/off valves are the smaller rim controls that switch a jet group's airflow fully on or fully off — and because they get turned with more torque than any other rim fitting, their caps and internals wear out first. This collection carries the standard On/Off Cap, the rotating Internal mechanism behind it, and the upgraded 2-Tone Bearclaw handle whose deep grip texture stays easy to turn with cold, wet hands.

A valve that's stiff, sticky or weeping at the rim usually needs a fresh internal and O-ring rather than anything serious. Replace cap and internal together — the threads engage as a set. All parts fit the standard Arctic Spas on/off valve assembly; bring the old part to any of our three Ontario showrooms if you're unsure.
