Pipe Couplings

Maxi-Range Pipe Couplings connect any two pieces of pipe of similar nominal size without disassmbly, or adapting end rings or transition gaskets. The Maxi-Range coupling is available 2" - 12". This ductile iron sleeve is rated at 250 psi and allows for up to ±5 degrees pipe.

  • Strong construction – Center ring and end ring are ductile iron.
  • SBR gaskets – seal over a wide range of pipe O.D. and exterior surface conditions.
  • Fully assembled – use as received without disassembly, modification, or parts change-outs.
  • Standard Cor-Ten Track head Bolting – with zinc corrosion protective coating and special shoulder under the head to prevent spinning while tightening; 304 stainless steel option.

Sizes: 2", 3", 4", 6", 8", 10", 12"

  • Standard bolts: Cor-Ten track head bolts with flash zinc coating and anti-spin feature, 304 stainless steel optional
  • Standard gaskets: SBR Center and end rings: Ductile Iron ASTM A536 65-45-12
  • 250 psig (1725 kPa/17 barg)
  • Pipe deflection: ±5 degrees
Note: Compression couplings of this type do not provide resistance to pipe pullout.
