NDS FLEXIBLE COUPLINGS
®

NDS Flexible couplings provide possibility of adopting NDS products to most sizes and types of piping required for effective drainage system functioning.

Product Features and Benefits

• Couplings and connectors fit over the ends of plain-end or spigot pipe to form a positive seal against infiltration and exfiltration in non-pressure
environments
• Durable PVC construction allows couplings to flex with normal earth movement
• Completely unaffected by soil conditions and resistant to chemicals, UV rays and normal sewer gases
• Dimensional flexibility ensures quick and easy installation of leakproof seal with virtually any pipe material

Materials & Standards

• Flexible couplings are made of elastomeric polyvinyl chloride (PVC) for long-lasting performance and durability
• Bactericides and fungicides are added to PVC for extra protection
• All clamps, including the band and housing, are made from stainless steel, offering corrosion-resistant, rustproof reliability

Installation

• Clamps install easily with a screwdriver, 5/16" (0.8 cm) nut driver or socket to 60 inch-lbs. torque
• All couplings are marked with size and pipe materials that the coupling will connect, eliminating guesswork on the job
• For more details about connections, see pages 22-23.
