Abstract
A tapping adaptor assembly for direct connection to a gate valve. The assembly includes a tapping adaptor attached to a main pipe. An outlet conduit formed integrally with and extend outwardly from the tapping adaptor terminates in a distal end outlet. A adaptor for mounting on the tapping adaptor includes an integral flange, a shoulder and a spout. The adaptor may be attached to the tapping adaptor by welding or glueing depending upon the material of the tapping adaptor or may be formed integrally with the outlet conduit. The flange of the adaptor has an annular face positioned to engage the gasket of the gate valve. The annular face may be recessed and an annular rim may be formed radially outwardly of the annular face. The spout of the mounting adaptor extends into the socket of the gate valve to help support the tapping sleeve. In an embodiment, a tapping sleeve semi-cylindrical section is formed integrally with the outlet conduit.
