Saddle Outlets
ANSI /AWWA Standards
Purpose and Use
U.S. Pipe’s saddle outlets should be considered and specified as an economical and readily
available alternative of 250 psi rated tees and tapping sleeves where branch outlets (4", 6", 8"
and 12") are required on pipe 16"-60" in diameter. Saddles are recommended for use on Ductile
Iron mains for pressure connections (wet taps). Also saddle outlets are recommended for branch
connections: tees, blowoffs, or devices such as air release valves, etc.
All saddles are rated for 250 psi operating pressure. Saddles are provided with a boss which can
be tapped for a 3/8" test plug.
Product Data
The saddle outlet body is made of Ductile Iron. Corrosion resistant straps and nuts are made of
the same corrosion resistant, high strength, low alloy steel used in mechanical joint bolts and
nuts. Pressure rating for the assembled saddle is 250 psi. 316 Stainless Steel Straps are
available by special order.
Types of Saddles
The counterbore dimensions conform to MSS SP-60 Connecting Flanged Joint Between Tapping
Sleeves and Tapping Valves. The counterbore mates with the projecting lip on the inside of the
flanged end of a tapping valve and ensures concentricity of the saddle/valve assembly and proper
alignment for the shell cutter of the tapping machine.
The presence of the counterbore on the flange does not affect the pressure rating and does not
prevent or interfere with the connection of any device such as a fitting, air release valve,
ASME/ANSI B 16.1 Class 125, or B 16.5 Class 150 flanges, etc. Rubber ring gaskets at least 1/8"
thick should be used with all flanged joints. U.S. Pipe’s FLANGE-TYTE® Gasket is recommended
and will be included with the saddle.

Application
For branch outlets (tee connections) in new construction, saddle outlets may be used and
should be considered for use in place of tee fittings or welded-on bosses. The saddle outlet
may be placed anywhere on the pipe barrel to suit the plan, thus eliminating the need to cut
the pipe to accommodate the precise location requirements of a fitting. Flanged saddle outlets
are suggested if a valve is to be attached to the saddle. Branch lines can be laid from the
valve after the main is pressurized and operational. Also, flanged saddle outlets are
recommended for the attachment of devices such as air release valves, blowoffs, etc.
Normally, saddle outlets are installed on pipe having a prepared, pre-cut hole. These “dry taps”
can be made anytime before the pipe is filled with water. Pipe with shop-cut holes can be
ordered from the factory (specify distance from centerline of hole to the face of the pipe bell and
the diameter of the hole).
For flanged outlets, dry taps can be made in the pipe with the use of a standard tapping
machine. Connect the tapping machine with the appropriate adapter directly to a flanged
saddle outlet and cut the hole or tap through a tapping valve connected to the flanged
saddle outlet.
Flanged saddle outlets are frequently used in wet taps or “pressure connections”. In these cases
the flanged tapping valve is mounted onto the saddle outlet and a special flange gasket is used.
A tapping machine with an appropriate adapter is then connected to the valve. The tapping
machine shell cutter removes a coupon from the pipe wall which is then withdrawn and the valve
is closed. This kind of tap is made without interruption of service and can be made on Ductile
Iron pipe. The use of a flanged tapping saddle, tapping valve, and tapping machine to make the
“pressure connection” is a safe, reliable and economical way to connect new pipe to an existing
Ductile Iron pipe main.

Assembly Instructions
1.Thoroughly clean the pipe barrel in the area to come into contact with the straps, saddle
outlet, and O-ring.
2.Use a grinder, if necessary, to remove any roughness from the pipe at the saddle outlet O-ring
sealing area
3.Insert the O-ring gasket into the groove on the underside of the saddle outlet.
4.Place the saddle onto the pipe and attach the straps.
5.Position the saddle over the pre-cut outlet hole or where the hole is to be cut with the
tapping machine.
6.Alternatively tighten the strap nut nuts until a uniform torque of 100 foot-pounds is attained.
7.If a dry tap is to be made, attach the tapping machine to the outlet and proceed with the tap.
The gasket mentioned in Item 8 (below) is not required.
8.If a wet tap is to be made, place the special tapping valve flange gasket provided with the
tapping valve onto the flange of the saddle. Attach the tapping valve to the saddle outlet,
then attach the tapping machine and proceed with the tap.
Precautions to Take When Making Taps in Iron Pipe
Prior to cutting or tapping a hole in the pipe, it is important to determine the exact outer diameter
of the pipe to ensure that the proper size saddle outlet is used and that the pipe diameters
conform to those specified in ANSI/AWWA Standard C151/A21.51.
U.S. Pipe does not recommend the use of saddle outlets on gray iron pipe. Extremely old gray
iron pipe may have outer diameters larger than pipe produced during the last 30 to 40 years.
Standard saddle outlets will not fit such pipe. It is also important to know if the pipe is Ductile
Iron or gray iron. Ductile Iron pipe has been produced only since the 1960’s.
Dry taps can be made in Ductile Iron pipe by using tapping machines or Oxyarc cutting
techniques. After tapping or Oxyarc cutting, the area should be carefully inspected for cracks
and, if found, they should be removed by grinding. If the pipe to be tapped has a special
external coating or internal lining, care should be taken to ensure that neither the coating nor
the lining is damaged in the tapping operation. Cut edges on such coatings or linings need to
be recoated to prevent undercutting and disbondment.
Wet taps should not be made in pipe which have special polymer linings since it is not possible
to recoat the cut edges after the tap is made. Oxyarc or similar hole cutting methods should
not be used on special polymer coated or lined pipe. Such high heat input cutting methods may
damage these coatings. Pipe with special lining can be furnished with shop cut holes if ordered.
