A 1 1/4 inch threaded heater element popular in many spas. Note that the 1.25 inch pipe thread actually measures 1 7/8ths. Available with or without adapter to replace older heater element assemblies that had the element welded directly to the back plate. This makes future replacement much easier.
Includes a heater element rated for 240V, 6000 Watts or 120V, 1500 Watts. Adapter plate is 2 11/16" in diameter, and comes with gasket and screws for easy installation.
Found in older model spas, namely Sundance, Jacuzzi, Polynesian and others.
The adapter is primarily used in Sundance Brand Spas.
