1 622 Tapping Sleeve Recessed cavity for mating to lip on standard tapping valves per MSS SP60. Heavy welded steel outlet half. 3/4-inch NPT test plug. Roll resistant, self-energizing concave wedge gasket. Double-radius head special alloy bolts with heavy hex nuts and flat washers. Cutaway View Showing Gasket Section Snug-fitting heavy steel back half eliminates deflection without shims or pads Benefits Reduces Inventory Built in range means one sleeve fits both classes of cast iron or asbestos cement pipe. Smith-Blair 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 weighs 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 of SmithBlair Tapping Sleeves means one sleeve fits several classes of pipe. Ease of Installation No caulking, welding or special tools needed. A wrench to tighten bolts is the only tool required to install a sleeve on pipe. Non-Standard Sizes Available Sleeves with heavy flanges or for non-standard size pipe are available on request. Time Saving A normal crew can install and complete taps in less time than it takes to install a caulk type sleeve. Reinforces Pipe Sleeve design directly reinforces pipe without need of shims or pads...also weighs less than heavy cast iron sleeves. 3

2 Smith-Blair 622 Tapping Sleeves consist of two sections of heavy welded steel that 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 per 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. Exclusive Concave Wedge Gasket g Roll Resistant Will not roll or bind on installation. g Self-Energizing Seal increases with line pressure. g Generous Cross Section Assures a good seal even on rough or pitted pipe. g Field Tested Field tests, as well as lab tests, have consistently proven wedge gasket performance superior to O-ring, modified O-Ring or flat gasket performance.
