Description

The Smith-Blair Style 372 is an all 304 stainless steel service saddle with two studs, designed for PVC pipe and suited to steel, ductile iron, cast iron, asbestos cement and other pipe types. Its 7-1/2 in wide band gives uniform sealing and pipe support without crushing action, and the outlet gasket is bonded into the band, with a hydro-mechanical lip that seals tighter as line pressure rises.

Each saddle covers both iron pipe size and ductile iron OD within the same nominal size, and a keeper bar helps pull the band around the pipe and close it during installation. It is used for new branch taps and to restore damaged or torn-out service connections, 4 to 16 in, with outlets from 1/2 to 2 in.

Application: new service taps and restoring damaged or torn-out service connections on PVC and other water mains, 4 to 16 in.

Key Features

  • Working pressure up to 150 PSI
  • All 304 stainless construction for corrosion resistance; wide band supports PVC without crushing
  • Outlet gasket bonded into the band, with a hydro-mechanical lip that seals tighter under pressure
  • One saddle covers iron pipe size and ductile iron OD in the same nominal size
  • Meets applicable portions of AWWA C230; certified to NSF/ANSI 61 and NSF/ANSI 372
What Ships and What It Needs to Run

Included: the 304 stainless band with its bonded Nitrile outlet gasket, lug bar, fingers and keeper bar, two welded 304 stainless studs, fluoropolymer-coated nuts and washers.

On HDPE pipe: spring washers are required on HDPE DR17 or thicker; they are a separate option, not included.

Installation Notes
  • Confirm the saddle OD range and tap match the pipe before starting; on HDPE (DR17 or thicker) fit the spring washers.
  • Clean the pipe where the outlet gasket will seat, removing scale, dirt or debris.
  • Wrap the band around the pipe with the outlet at the tap location; the keeper bar helps pull the band around the pipe and close it.
  • Tighten the two nuts evenly so the band draws down uniformly; follow the instructions packed with the saddle for torque.
  • Make up the service connection with a thread compound that meets the water supplier's requirements.

From the Smith-Blair Style 372 datasheet and specification sheet (Rev 02/14/23), in the Data Sheet tab; follow the instructions packed with the saddle for torque.
