T-connector definition
Any connector in the shape of the letter "T" -- often referring to a hollow unit. For example, the line coming from the windshield washer pump is connected to the bottom part of a "T" and the crossbar at the top sends the fluid to the two nozzles (one on each side of the windshield ). It differs from a Y-connector in that the crossbar is straight across while the Y-connector has a V-shape crossbar.
