A spa circuit board is the "brains" behind your spa, controlling jet flow, filtration systems, water temperature, as well as the unit's high-limit sensors. Master Spa Parts offers a number of replacement circuit boards.
Connect your audio system to the controller of your Master Spa hot tub using this stereo adapter. Order the stereo adapter you need for your Master Spa controller today.
The heater gasket o-ring is a replacement part for the o-rings that come with your spa and support the heater gasket so that there is a tight fit. If you don’t see your model listed, it may still work – so please give our customer service a call!
