Description

The Smith-Blair Style 311 is a single-bale ductile iron service saddle with a TaperSeal gasket and a wraparound bale, used to connect branch lines, instruments and other appurtenances to the pipe. The wide, wraparound body with a heavy tapping boss sits stable on the pipe, and the TaperSeal lip lets the saddle hold pressure with minimal nut torque.

Choose the pipe size and OD range in the first option and the outlet in the second: CC (AWWA corporation-stop thread) from 5/8 to 1-1/2 in and NPT from 3/4 to 2 in, from 1 in to 12-14 in nominal pipe; not every tap is made on every pipe size.

Application: tapping pipe for branch and service connections and installing air and vacuum valves, drain valves, pitot tubes and other service equipment.

Key Features

  • Working pressure up to 200 PSI, depending on size and application
  • Wide saddle body and heavy tapping boss give stability on the pipe
  • Gasket is fully cemented in its cavity to hold it in place
  • A closed lug on one side works with the bale as a hinge for easier installation; the open lug slips on without removing the nuts
  • Meets applicable AWWA C800 standards; certified to NSF/ANSI 61 and NSF/ANSI 372
What Ships and What It Needs to Run

Included: the epoxy-coated ductile iron saddle body with the gasket cemented in place, one electro-galvanized steel bale, nuts and washers, ready to install.

Outlet: supplied with the CC or NPT tap chosen in the options; the outlet connection is made with pipe thread compound, not tape.

Working Pressure

Up to 200 PSI. depending on size and application. Smith-Blair notes that the allowable pressure depends on the type of pipe, pipe diameter, service conditions and installation workmanship.

Pipe Applications

Steel, ductile iron and cast iron pipe per the datasheet; Smith-Blair's spec adds stainless steel, asbestos cement and aluminum. Bale saddles are not recommended on PVC or HDPE pipe; Smith-Blair's stainless strap styles are built for those.

Installation Notes
  • Confirm the saddle type, tap size and pipe OD range before you start, then clean the pipe thoroughly where the gasket will seat, removing scale, dirt and debris.
  • Check that the gasket sits properly in the body, then lubricate the pipe surface and gasket with a soap-and-water solution (anti-freeze may be required) that meets the water and pipe supplier's requirements.
  • Mount the body as close to the final tap position as possible and set its orientation before tightening; do not move the body once it is on the pipe, as this can damage the gasket.
  • Fit the bale, washers and nuts, with the washers on the open-lug side; tighten the nuts progressively and uniformly to the torque in the instructions, keeping the bolt lengths on both sides equal. Do not over-torque; a calibrated torque wrench is recommended.
  • Make the outlet connection with a good-quality pipe thread compound that lubricates and seals (no tape products) and meets the water supplier's requirements; do not cross-thread or rock the body while threading.
  • The torque is set to seal the gasket to the pipe: the saddle is not designed to give structural rigidity to connections or equipment, and Smith-Blair does not recommend bale saddles on PVC or HDPE pipe.
