Smith-Blair Style 622 Carbon Steel Tapping Sleeve - Flanged Outlet, 304 SS Bolts, 4-30 in

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 flanged 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
• Outlet flange recessed for tapping-valve alignment per MSS SP-60
• 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

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.

Materials subject to change by the manufacturer.

Carbon steel, stainless steel, cast iron, ductile iron, asbestos cement, PVC and HDPE pipe. PVC: DR 25 or thicker wall. HDPE: SDR 17 or heavier wall, underground service only, and a cutter 2 in smaller than the nominal outlet. Pipe must be round where the sleeve seats.

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.

• 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. Smith-Blair recommends 1/8 in ring-style elastomeric valve flange gaskets.
• 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.
