411 Steel Fabricated Coupling

Description: A bolted sleeve type coupling for joining plain end pipe of the same diameters.
Application: Joining plain end pipe without the need for welding or special pipe fittings.
Key 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
• Available in a wide variety of pipe O.D. sizes and sleeve lengths
• Most sizes will accommodate anchor studs to restrain the joints
• Can be custom made to fit odd O.D.s 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 O.D. and Ductile Iron sizes are built with range to accommodate the variances in
 Ductile Iron pipe O.D.s
