432 Stainless Steel Saddle Specifications:

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.

Service Saddle Installation Instructions

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:

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.

1. The nuts and bolts are made from material of different hardness so that they have different strengths.
2. The nuts are coated with a special (antiseize) coating.
3. Each nut is assembled by hand to be sure that it went on the bolt freely.
4. The bolts and nuts are handled carefully to avoid damage to the threads.
5. The bolts and nuts are made to exacting specifications to assure that the correct material is used and that the thread form is correct.

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.
