Where to Buy
The NDS 3/4 in. SIDIR-7 Flo-Lock™ Gripper Coupling for PE Pipe fully unassembled showing the steel gripper, EPDM O-Ring and stiffner (NDS 810-07)

Key Features

  • Flo-Lock™ couplings and adapters are used to connect pipes; Flo-Lock™ products are installed in tubing or pipe systems to allow water to flow through freely
  • NDS offers a wide range of Flo-Lock™ gripper couplings and adapters to  work with a variety of pipe sizes and types
  • Gripper coupling provides a leak-resistant connection between two pipes
  • Gripper adapter provides a leak-resistant connection between smooth pipe and threaded pipe end
  • Gripper couplings and adapters are made of polyvinyl chloride (PVC)

Applications

  • Flo-Lock pipe couplings and adapters make water service line installations easy and provide a leak-resistant joint with less chance of pipe pull-out
  • Use for pool and spa, irrigation, and plumbing applications; works with most plastic pipe to transport water and provide a leak-resistant connection
  • Flo-Lock™ gripper fittings connect two pipes to allow water to flow through

Installation & Maintenance

  • Coupling has two compression ends that connect onto pipe; no glue required
  • Adapter has one compression end that connects onto pipe and one threaded end that connects to pipe end; no glue required
  • Gripper fitting performance issues can indicate damage; replace as needed

Materials & Sustainability

  • Gripper couplings and adapters are made of polyvinyl chloride (PVC)
  • Gripper is made of steel; EPDM O-Ring
  • Parts made in the USA
  • Onsite flow management helps provide a leak
  • and corrosion-free system
