This Temperature Sensor Set has 1/4" probe widths on both probes.. This set usually found on tubs with no heater that uses a firestick or heat jacket to heat not a real heater... I have seen these on Dreammaker and other brands... The temp probe is larger on most sensor sets this one has the smaller temp probe to fit in a thermowell that is in the plumbing not in the wall of the tub... Measure both probes before ordering this set...
