Tapered Self-Threading Plugs
New products from Mazco
Mazco manufactures tool adapters and tapered threaded plugs for stopping gas flow in service tee connections. They are available from 1/4" and up, for threading into concentric holes drilled in the main or perforator type holes in the main.
Mazco manufacturers tooling to remove perforators on clamp-on or welded service tee connections and installing these tappping plugs as the initial closure to stop flow. Clamp-on devices can be completely removed from the main line without interupting main line flows.
Mazco also manufactures over-drilling tooling for torched or burnt holes in the main, to make them concetnric and allow the plug to be inserted.
