Description

The Smith-Blair Style 413 is a bolted steel transition coupling that joins plain-end pipe of different outside diameters within the same nominal pipe size, such as two pipe materials of the same nominal size, when the OD difference stays within the coupling's listed range. A straight fabricated steel sleeve and two followers compress a Nitrile gasket onto each pipe end, with low-alloy steel bolts and nuts.

Each end is sized on its own: choose the nominal size and End 1 OD range in the first option and the End 2 OD range in the second. Order by the exact ODs of both pipes, not the nominal transition.

Application: joining plain-end pipe of different ODs within the same nominal pipe size, 2 to 24 in.

Key Features

  • Working pressure up to 150 PSI
  • Separate OD range at each end for a true transition in one coupling
  • Allows limited expansion and contraction and dampens vibration to reduce pipe fatigue
  • No special pipe-end preparation; deflects to change pipe direction without elbows or bends
  • Meets applicable AWWA C219; certified to NSF/ANSI 61 and NSF/ANSI 372
What Ships and What It Needs to Run

Included: the steel sleeve, followers, Nitrile gaskets and the bolts and nuts, ready to install.

Pipe stiffeners on HDPE, ordered separately. Smith-Blair requires pipe stiffeners when the coupling is used on polyethylene pipe; ask us to quote them with the coupling.

12-Month Smith-Blair Warranty

Smith-Blair warrants its products to be free of defects in materials and workmanship for one year from the date of shipment by Smith-Blair. Dated proof of purchase, such as a bill of sale, is required to establish eligibility. Smith-Blair will repair or, at its option, replace a defective product; the product is returned to the factory or warehouse Smith-Blair designates.

Working Pressure

Up to 150 PSI, the standard design rating. Smith-Blair notes that a coupling's working pressure depends on pipe type and diameter, sleeve thickness and material, gasket cross section, follower type and number of bolts; higher-pressure designs are built to order.

Installation Notes
  • Pipe stiffeners are required when the coupling is used on polyethylene (HDPE) or thin-wall PVC pipe.
  • Clean the pipe ends, then slide a follower onto each pipe, followed by a gasket with its beveled edge facing the pipe end; lubricate the pipe and gaskets with a soap-and-water solution that meets the water and pipe supplier's requirements.
  • Center the pipe gap in the sleeve: with a 5 in sleeve aim for 1/2 in on a straight run and no more than 2 in; a 7 in sleeve takes a gap of up to 3 in.
  • Hand-tighten the nuts, then tighten gradually, alternating between opposite sides so the followers stay parallel, to the torque in the instructions; recheck torque after the line is pressurized.
  • Allowable axial pipe movement per coupling is 1/8 in through 2 in nominal, 1/4 in over 2 to 10 in, and 3/8 in above 10 in.
  • Anchor the pipe: the coupling seals around it, and Smith-Blair requires proper anchoring to restrain pipe movement and prevent pull-out.
