Description
The Smith-Blair Style 622 is a fabricated carbon steel tapping sleeve for size-on-size and reducing branch taps on new or existing water mains, 4-30 in runs with 4-12 in mechanical joint (MJ) outlets. The two-piece body is Flexi-Coat fusion-bonded epoxy coated, with V-lugs, a Nitrile gasket cemented in a machined recess and a 3/4 in test outlet to pressure test before you tap.
This listing carries Type 304 stainless steel bolts and nuts for buried and corrosive service. Choose the run size and measured pipe OD, then the outlet size; the part number follows.
Application: Tapping size-on-size and reducing branch connections and installing valves on new or existing pipe.
Key Features
- Working pressure up to 175 PSI; test pressure 262 PSI
- Full 360° gasket support around the pipe; the gasket seal increases with line pressure
- MJ outlet for mechanical joint tapping valves
- 3/4 in NPT test outlet to hydrostatically test the sleeve before tapping
- Certified to NSF/ANSI 61 and 372; meets applicable portions of AWWA C223; epoxy meets AWWA C213
What Ships and What It Needs to Run
Included: both sleeve halves with the gasket installed, the bolts, nuts and washers, and the 3/4 in test outlet with plug.
Needed to complete the tap, ordered separately: the MJ tapping valve, connected with gasket and hardware per AWWA C111, a tapping machine and shell cutter, and thrust blocking with permanent support under the valve.
Genuine Smith-Blair equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
12-Month Smith-Blair Warranty
Smith-Blair warrants its products to be free of defects in materials and workmanship for one year from the date of shipment by Smith-Blair. Dated proof of purchase, such as a bill of sale, is required to establish eligibility. Smith-Blair will repair or, at its option, replace a defective product; the product is returned to the factory or warehouse Smith-Blair designates.
Working Pressure
Up to 175 PSI. Test pressure 262 PSI. The working pressure of any tapping sleeve falls as pipe diameter rises; for a particular installation it also depends on the pipe type and condition, service conditions and workmanship, and never exceeds the rating of the pipe.

Choose the run size and pipe OD in the first option and the outlet size in the second; the part number shows in the last option.
Installation Notes
- Check the pipe OD and roundness where the sleeve will sit, then clean the pipe thoroughly, especially where the gasket seats.
- Lubricate the pipe and gasket with a soap-and-water solution that meets the water and pipe supplier requirements. Mount the halves with the test outlet accessible; do not slide or rotate the sleeve on the pipe.
- Hand tighten, then tighten the nuts from the center outward, alternating sides and keeping equal gaps, until the halves conform to the pipe and reach the torque in the instructions. Use a calibrated torque wrench.
- Block the tapping valve and machine and give the valve permanent support and thrust blocking. On the MJ outlet, use only gaskets, hardware and procedures per AWWA C111.
- Hydrostatic test only, never air: test the sleeve, outlet joint and valve to no more than 1.5 times line pressure before tapping.
- Size-on-size taps on IPS pipe take a cutter at least 1/2 in smaller (12 in outlet on 12.75 in pipe: 11.5 in cutter). Re-torque after the tap and recheck the nuts 12-24 hours after installation.
