Features

  • They offer ductile iron construction for dampening vibrations and allowing limited pipe expansion and contraction.
  • They feature a nitrile gasket to resist water, oil, natural gas, acids, alkalis, hydrocarbon fluids and many other chemicals.
  • These couplings can be used for standard pipe sizes up to 12 inches and are capable of withstanding a maximum pressure of 250 psi.

Standards and Approvals

  • ANSI A21.11
  • ASTM A536
  • AWWA C219
  • NSF 61
  • NSF / ANSI 372

Frequently Asked Questions

What is the purpose of the flanged design?

The flanged design of these couplings helps to connect two tube / pipe ends seamlessly without causing drag or resistance in the material being passed through them.

What pipe materials are these couplings used for?

Carbon steel, stainless steel, ductile iron, Asbestos Cement, PVC, HDPE and copper.

Are these couplings corrosion-resistant?

Smith-Blair couplings feature a Flexi-Coat fusion-bonded epoxy-coated finish for superior corrosion resistance, providing a safe use in non-potable water piping systems.
