Disclosed is an apparatus for connecting a service line at a right angle to a main, having a fitting with one end shaped to be fixed to the exterior surface of the main in a plane with the fitting extending horizontally from the main. First and second through bores are formed in the fitting. These bores are axially spaced and positioned in the fitting to radially extend from the main when the fitting is fixed thereto. A port adjacent the end of the fitting shaped for connection to the exterior of the main interconnects the two through bores. Means is provided in the first through bore for connecting a service line to the fitting to extend radially from the center of the main. Internal threads are formed in the second through bore for receiving an externally-threaded tapping means for manipulation axially through the bore to cut a coupon from the wall of the main to interconnect the main with the first through bore. A sealing plug is provided for sealing the open end of the second through bore.
