ABSTRACT:
A by-pass level indicator includes a main tube in communication with a tank via a pair of by-pass tube members, a float containing a magnet and an indicator attachably mounted to the main tube and having a series of magnetic colored flags reacting with the magnet of the float for indicating level of the tank. Each of the by-pass tube members includes a T-joint having an upright tube receivably engaging with one end of the main tube and a transverse tube integrally extending from the upright tube communicating the main tube to the tank. The transverse tube has a male threaded end portion to partly receiving an O-ring. The by-pass tube member further has a combination of a union and a collar adapted to communicating the transverse tube with the tank. The collar is threadingly engaged with the male threaded end portion of the transverse tube and clamps a connecting tube of the union to the transverse tube simultaneously compressing a protruding portion of the O-ring, thereby achieving a fluid-tight seal.
