The Tapping Sleeves consist of two sections of heavy welded steel which bolt together on the pipe and seal against a concave wedge gasket around the tap opening. The outlet half has a recessed flat faced flange to mate with standard tapping valves MSS SP60 up through 12-inch size-on-size. For tap sizes 14-inch and above, flanges can be furnished to accommodate the valve requirements. The outlet half also has a 3/4-inch NPT test plug.
Built in range means one sleeve fits both classes of cast iron or asbestos cement pipe. Tapping Sleeves are fast and easy to install with simple hand tools, require no caulking or special equipment, and may be used with any standard tapping valve. The sleeve design directly reinforces pipe without shims or pads and also weights less than heavy cast iron sleeves. The self-energizing gasket will not roll or bind on installation, and has a generous cross section to assure a good seal every time. The built-in range means one sleeve fits several classes of pipe.
Normal crew can install and complete tap in less time than it takes to install a caulk type sleeve.
Ease of Installation
No caulking, welding or special tools needed. A wrench to tighten bolts is the only tool required to install sleeve on pipe.
