Product Details

  • Reduce water hammer caused by quick valve closure
  • Water hammer arrestors are designed to protect residential, commercial and industrial water lines during pressure surges following quick valve closure, i.e. fast closing solenoid valves on water lines
  • The excessive pressure surge is absorbed by the pre-charged cushion of air permanently sealed within the water hammer arrestor
  • Maximum transient pressure surge, with arrestor properly sized and placed in the water supply system, will not rise above 150 psi following quick valve closure
  • Arrestors have static pressure rating of 150 psi, but for best performance static pressure should be not exceed 85 psi with a maximum flow velocity of 10' per second
  • Seamless copper tube body has a brass tailpiece with MNPT connection, acetal (NSF Listed) or brass piston, FDA approved Buna-N O-rings and lead free solder
