EXTRA BOLTING POWER...The true tapping sleeve design of this sleeve incorporates replaceable, self-aligning bolts, which facilitate conversion of high bolt torques to high gasket pressure. (Can be torqued to 125 ft. lbs) This increases gasket sealing pressure and pressure holding capability.
FULL CIRCUMFERENTIAL SEAL...The extra bolting power assures the gasket will seal the full circumference of the pipe. This provides insurance against beam breaks in size on size taps. Molded-in recessed bridge plate, assures even gasket pressure throughout the range of the sleeve.
STRONGER YET LIGHTER THAN CAST SLEEVES...Extra strength eliminates possible cracking of the sleeve or flange. Reduced weight speeds installation and reduces the load placed on the pipe.
EXTRA WIDE FOR SUPPORT AND STABILITY...Extra width, and heavier neck and body material, provide extra reinforcement of the outlet and extra stability during the tapping process.

Tapping sleeve shall be fabricated from 304 Stainless Steel or its equivalent, CF8 Cast Stainless Steel. They shall have a pass through bolt design and provide 360o seal around the pipe. The 432 is fully passivated to return the stainless steel to its highest corrosion resistance. Sleeves shall be manufactured to meet the following minimum specifications.
1. Determine O.D. of Pipe.
2. Specify sleeve number EXAMPLE and outlet size. For A/C pipe with 14.20 O.D. with 6" outlet
3. Select proper Sleeve O.D. For stainless steel flange order: 432-1420 x 6 range. For carbon steel flange order: 462-1420 X 6
4. Add your size tapping saddle to our shopping cart and use a credit card at checkout.
-Thoroughly clean pipe surface. Check the size and range of the tapping sleeve to verify correct size product.
- Check surface of pipe where tapping sleeve will be installed to make certain pipe is free of flaws, gouges and extreme irregularities.
-Lubricate pipe and face of gaskets with water or soap-water. Do not use grease or pipe lubricant.
-Position back half of body over tapered gasket edges, extending from outlet half of body, and install bolts. NOTE: For nominal pipe sizes 10" and larger an additional set of washers has been provided. To assure ease of installation, and to obtain optimum bolt torque levels, install a double set of washers under each nut.
-Make certain the tapered edges of the gaskets are smooth.
-Tighten outside bolts first, working toward the center. Tighten both top and bottom bolts evenly. Alternate from one side of sleeve to the other. Tighten to the following torque levels:
4" - 8" Nominal Pipe Sizes, 10" Size 4" - 8" outlets 85 ft. lbs. minimum -125 ft. lbs. maximum
10 x 10 Sizes and Larger Nominal Pipe Sizes 100 ft. lbs. minimum -125 ft. lbs. maximum
Thin wall, flexible, class PVC (SDR 21, 26) pipe 50 ft. lbs. minimum -55 ft. lbs. maximum
Check inside of sleeve neck to make certain gasket is properly seated and not protruding where tapping cutter may damage it.
Install tapping valve. Adherence to the AWWA M-44 Manual for proper valve installation, support and trenching is recommended.
Test assembly seals with water (per AWWA C-223) using test plug provided on sleeve or test connection on tapping machine. Note: No more than 10% above line pressure unless approved by system owner/operator, maximum pipe working pressure, or maximum sleeve test pressure of 200 PSI.
When assured that all seals are tight and test is completed, re-check bolt torques after 15 minutes and proceed with tapping operation.
|Note:||Size on size tapping cutter must not be larger than recommended by pipe manufacturer.|
|??||Also, tapping operation must not force the pipe away from the gasket seal.|
|Note:||For care of stainless steel bolts and nuts, see reverse side.|
RECOMMENDATIONS FOR INSTALLATION OF FITTINGS WITH STAINLESS STEEL BOLTS AND NUTS
This quality fitting is equipped with 18-8 stainless steel bolts and nuts for superior corrosion resistance.
The galling and freezing action is often triggered by the presence of metal chips, burrs, and grains of sand on the threads of the bolts and nuts.
Extra care has been taken prior to the assembly, and the packing of this fitting; to assure a trouble-free installation.
However, it must be pointed out that during field installation, the threads MUST BE KEPT CLEAN AND FREE FROM NICKS.
When a mild steel or bronze bolt is used, the low ultimate strength of the material allows the nut to tear itself free.
Not so with 18-8 Stainless Steel. The ultimate strength of the material is so great, that it increases rapidly with cold work. However, once foreign matter such as a grain of sand wedges the threads, or the thread form is altered by over-torquing, the nuts cannot be removed.
The specially coated nuts are supplied to help eliminate the galling caused by over-torquing; but the bolts must be kept clean and not pitched or thrown into the tool bucket during installation. Should additional lubrication be required, a Molybdenum-Base lubricant is recommended.
NOTE: Installation of this fitting with a pneumatic wrench may cause seizure of the nut. A Master Wrench or 905 Torque Wrench with a "Deep Socket" is recommended.
