Water or Flexible Gas Pipe Clamps

Water or Flexible Gas Pipe ClampsPrint this page

ERITECH® brand of CWP grounding clamps are listed for connecting HEX Fittings on CSST systems.

ERICO® has developed a range of CWP Grounding Clamps which help minimize the possibility of damage from a lightning strike or other transient voltage by reducing the electrical potential between metallic objects and building systems.

The clamps, which are part of the ERITECH® line of Facility Electrical Protection products, conform to the requirements of the 2009 edition of NFPA® 54, NFGC® (National Fuel Gas Code) and NEC® (National Electric Code) for bonding corrugated stainless steel tubing (CSST) gas piping systems to the grounding conductor of the building’s electrical system.

CWP Grounding Clamps are ideal for connecting brass hex fittings on flexible gas piping, copper grounding conductors, galvanized water pipes, copper water tubing or ground rods ranging from 1/2” to 4” to a ground conductor to bond all ground points together. This helps eliminate ground loops and creates an equipotential plane.

Made of a high-strength silicone bronze, the clamps are ideal for use in applications, such as lightning protection, fault current ground, signal reference grid and static ground. They are UL® Listed (ANSI®/UL 467 Category KDER).



Features

  • Ideal for connecting copper conductors to metallic water pipe (including copper tubing or ground rods)
  • Bond corrugated stainless steel tubing (CSST) or flexible gas pipe systems to the electrical system in accordance with the NFGC (National Fuel Gas Code) and the NEC (National Electric Code)
  • Applications include lightning protection, fault current ground, signal reference grid and static ground
  • CWP series of clamps fits hex fittings, copper grounding conductors, galvanized water pipes, copper water tubing or copper ground rods ranging from 1/2” to 4”
  • UL® Listed (ANSI®/UL 467 – Category KDER)
  • High-strength silicone bronze clamps connect brass hex fittings

Applications

CWP Grounding Clamps help minimize the possibility of damage from a lightning strike or other transient voltage by reducing the electrical potential between metallic objects and building systems.
