About this item

Smith-Blair Straight Coupling, Series: 411, Fitting/Connector Type: Coupling, 2-1/2 in Nominal, 0.203 in Thickness, 5 in Length, 150 psi, Method of Manufacture: Fabricated, Carbon Steel, Epoxy Coated, -20 to 180 deg F, 2.88 in OD

Smith-Blair steel couplings offer many distinct advantages when installed in a piping system. Properly selected and installed flexible couplings maintain the continuity of the pipe system, retain the line contents under internal pressure and prevent infiltration under vacuum. Our couplings consist of one cylindrical sleeve with conical inner surfaces at each end, two resilient, wedge-shaped, specially-compounded rubber gaskets, two ring-shaped followers and a set of high-strength, low-alloy track-head, oval-neck, rolled-thread bolts with heavy hex nuts.

Brand Smith-Blair
  • A bolted sleeve type coupling for joining plain end pipe of the same Dias
  • Allows for limited expansion and contraction
  • Will dampen vibration to reduce pipe fatigue
  • Easy to install, no special pipe end preparation required
  • Most sizes will accommodate anchor studs to restrain the joints
  • Can be custom made to fit odd ODs or other unusual applications
  • Provided with or without pipe stops to accommodate customer needs
  • Has good deflection capabilities, allows change in piping direction without the need of elbows, bends
  • Steel sizes built to specific OD and ductile iron sizes are built with range to accommodate the variances in ductile iron pipe ODs
  • Ductile iron or steel follower designed for a high strength-to-weight ratio
  • High strength low alloy steel bolts with heavy semi-finished hexagon nuts
  • Nitrile (Buna-N) gasket compounded to produce superior storage and performance characteristics while resisting water, acids, alkalis, most (aliphatic) hydrocarbon fluids, and other chemicals
  • Carbon steel having a minimum yield of 30000 psi
  • Flexi-Coat® fusion bonded epoxy coated finish
  • 5/8 in Dia x 8 in L bolt
  • 6-1/2 in OD flange
