Flexible Caps and Couplings

Flexible Caps and Couplings

Form a leak-resistant seal between pipes with the flexible coupling. Close off the end of pipeline in a non-pressurized system with a flexible end cap. Flexible adapters help stop leaks around pipe entering concrete manhole walls.

Key Features

  • Flexible couplings flex with normal earth movement and is unaffected by soil conditions; resistant to chemicals, UV rays and normal sewer gases
  • Flexible caps have reinforced convex faces to withstand greater testing pressure; minimizes ballooning; has a 5 PSI maximum
  • Flexible adapters allow some lateral pipe movement around pipe entering concrete manhole walls; maintains integrity of seal
  • NDS offerings also include drain and trap connectors
  • Flexible caps, couplings, and adapters are made of flexible elastomeric polyvinyl chloride (PVC)

Applications

  • Flexible couplings connect clay, concrete, or asbestos cement fibre/ductile iron pipe to cast iron/plastic/copper/steel/lead pipe; coupling flexibility provides leak-resistant seals with virtually any pipe

  • Flexible caps stop the flow of water at the end of the pipeline; closes off pipe; remove cap to flush pipe system

  • Flexible adapters works with most plastic pipe to transport water through manhole wall and provide a leak-resistant connection

Installation & Maintenance

  1. Coupling and cap have clamped end(s) that slide onto pipe;
  2. Tighten clamp(s) with screwdriver, 5/16 in. nut driver or socket to 60 inch-lbs. torque
  3. Adapter screws onto pipe

  • Performance issues can indicate damage; replace as needed

Materials & Sustainability

  • Flexible caps, couplings, and adapters are made of flexible elastomeric polyvinyl chloride

  • Clamps are made of series 300 stainless steel

  • Onsite flow management helps provide a leak-resistant and corrosion-free system
