Abstract
A tapping sleeve assembly for direct connection to a gate valve. The assembly includes a tapping sleeve attached to a main pipe. An outlet conduit formed integrally with and extend outwardly from the tapping sleeve terminates in a distal end outlet. A retaining ring is attached to the outer surface of the outlet conduit and is located between the tapping sleeve and the distal end outlet. Opposed, longitudinally facing annular surfaces are formed on the retaining ring with one of the annular surfaces facing the tapping sleeve and the other facing the distal end outlet. The annular surface facing the tapping sleeve is inclined. A gland telescopes over the outlet conduit. The gland has a collar with an annular surface engaged with an annular surface of the retaining ring. A gate valve has a socket facing the outlet conduit, a gasket is positioned in the socket and a mechanical joint flange surrounds the socket. Bolts and nuts attach the gland to the mechanical joint flange of the gate valve.
