Product Details

Cap Your Valves & Outlets

Fire hydrant & standpipe valve caps and plugs ensure hydrants keep functioning correctly and efficiently. Designed to prevent foreign matter entering hydrant outlets, they reduce the need for maintenance and repairs.

Caps helps prevent unauthorized hydrant use, reduces water theft, reduces hydrant vandalism, and lowers operation costs. This design fits every hydrant from every manufacturer conforming to standard 1-1/2" NST (NH) threads, regardless of year or model. 


  • Full Brass 
  • Cap & Chain
  • 1.5" NH / NST (National Hose / National Standard Thread)

Standard everyday street fire hydrants are provided with a plurality of threaded outlets to which hoses may be connected (by far the most common is 2.5" NH/NST).  Common fire standpipe valves range from 1.5" NH/NST to 2.5" NH/NST.  A cap is mounted over each outlet for closing off outlets and a cap is removed when a hose is to be connected thereto.  The fire hydrant is also provided with a valve operated externally of the fire hydrant by a standard wrench and in order to draw water from the fire hydrant, it's necessary to both open the valve and remove a cap from one of the outlets.  

Unauthorized use of fire hydrants during hot weather is a common occurence and cusch uses are wasteful of water and cause a drop in water pressure in system which feeds the fire hydrant.  Unauthorized uses have generally been possible since, with the prior constructions, the fire hydrant valve can be operated and one or more caps removed by means of tools and wrenches commonly available to members of the general public.
