The AMERICAN Captivater® - Locking Nozzle Cap

The Captivater®, by AMERICAN Flow Control, helps prevent unauthorized hydrant use, helps conserve water, reduces water theft, helps prevent hydrant vandalism, and lowers operating costs. As long as the threads are compatible, its universal design fits EVERY hydrant from EVERY manufacturer, regardless of year or model.


  • Easily fits virtually any make, model or year of hydrant without modification
  • No special tools are required to install
  • Provides a quick and easy method to secure fire hydrants
  • Each cap is sealed to help protect the working parts from the elements
  • Withstands weather and long-term use as well as original caps
  • Removed only with a Captivater™ wrench
  • Each wrench has a serial number allowing hydrant access to be controlled
  • Doesn’t call attention – Caps looks similar to those on a standard hydrant

What does this mean?

Your hydrants are secured from unauthorized use, so children and vandals (or people with more sinister plans) cannot gain access to your water system.
