Abstract
A bushing for a hot water tank to connect a temperature sensing probe of a temperature controller device to the tank wall with the temperature controller device extending into the tank. The bushing is comprised of a cylindrical body having an outer connecting portion and a cylindrical inner bore portion. The temperature sensing probe is retained at a fixed position in axial extension through the inner bore portion. The inner bore portion has three equidistantly spaced-apart circumferential seal receiving channels with an O-ring seal receivable in friction fit in each of the channels. A central one of the O-rings provides a pivot for the probe and a substantially leak-proof seal about a cylindrical body portion of the temperature sensing probe. An outer and inner one of the O-rings resist to opposing load forces created by the load of the temperature controller device secured to an outer end of the temperature sensing probe, and equilibrates this load about the central O-ring.
