ABSTRACT:
The tapping apparatus includes a body that receives a cutter and sleeve. The cutter and sleeve advance together to form an opening in the sidewall of a main conduit about which the body is secured. The sleeve includes external threads that grip into the conduit sidewall. Thereafter, retraction of the cutter leaves the sleeve in place to secure the tapping apparatus to the conduit and establish fluid communication therethrough. The cutter and sleeve preferably have different thread pitches so that the sleeve advances at a slightly faster rate than the cutter. This facilitates sealing engagement between the external surface of the main conduit and the body. Additionally, a one-way drive arrangement is provided between the sleeve and cutter so that once the sleeve is positioned in place, the cutter can be removed without altering the location of the sleeve.
