Description

Smith-Blair Coupling, 4 in, 4 in, 4 in, Flanged Connection, Steel, Finish: Flexi-Coat® Fusion Bonded Epoxy, 150 psi, -20 to 180 deg F, 4-1/2 in Outer Diameter, 4 Bolts, 5/8 in Dia x 13-1/2 in L Bolt, 12 in L x 0.188 in THK Sleeve, Applications: Water and Industrial Piping, Joining and Repairing, Standards/Approvals: AWWA C219/C213, NSF/ANSI 61/372

A bolted sleeve-type coupling for joining plain end pipe of the same diameters. 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.

Features

• Meets applicable AWWA C219 standards 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
