Different threads can put mutual aid responders at a significant disadvantage. Harrington Hydrant Storz connections offer a permanent fix to the problem.

It's a problem as old as fire fighting itself. First, there is the plant. It was built to be interchangeable with any of the other plants the same company owns, right down to the threads on the fire hydrants. The fact that the local municipal fire department may use a different thread was never taken into consideration.
The different threads put the municipal firefighters at a significant disadvantage if they ever assist the plant fire brigade. Harrington, Inc., of Erie, PA, offers a painless way to hydrant-hose interoperability with their line of hydrant Storz connections.
Storz is a type of hose coupling comprised of interlocking hooks and flanges. It is sometimes referred to as a sexless coupling because rather than having a male and female end connected by screw threads, either identical end can be joined to any other end of the same size.
"It's a quick-connect hose coupling, a standard on large diameter fire hoses across the country," said Dave Harrington of Harrington, Inc. "It's basically a quarter turn connection, which is a huge time savings, except when the hydrant connection is a male thread, not Storz. With a threaded nozzle, the fire department must first adapt the fire hydrant to be compatible with the fire hose. Nothing quick about that! With Storz connections on the fire hydrants permanently, it's just a quarter turn cap off, quarter turn hose on. No more thread delays."
The Harrington Storz adapters - both the Harrington Permanent Hydrant Adapter (HPHA) and the Harrington Integral Hydrant Storz (HIHS) -- eliminate the need for an intermediate adapter.
The HPHA is designed specifically for retro fitting existing hydrant threads. The adapter is threaded onto the steamer nozzle and secured permanently with two setscrews.
A Storz spanner wrench is required for cap removal, preventing vandalism. The adapter has a hard anodized aluminum metal face seal, ramps and lugs. Its finish is hard coat anodized. The adapter itself is made of forged aluminum.
"The metal face seal on the hydrant connection eliminates gasket related issues such as aging or wear," Harrington said. "Two rubber gaskets against one another have the potential of being stuck together, which would increase your difficulty."
The HPHA has a solid track record. Cities in Washington state, such as Tacoma, have been specifying it since the mid-1970s.
"In the case of Tacoma there were three different thread specs on their hydrants," Harrington said. "Identifying hydrant threads was very time consuming, and they required a multitude of adapters."
Harrington's Integral Hydrant Storz nozzle is installed on new hydrants during assembly. The nozzle is built into the hydrant in place of the male threaded nozzle. Once installed, the Storz with cap extends less than two inches from the hydrant nozzle. With the HIHS, as with the HPHA, a Storz spanner wrench is required for cap removal.
Like the HPHA, the HIHS has a hard anodized aluminum metal face seal, ramps and lugs. The adapter itself is forged or extruded aluminum with a hard coat anodized finish.
Beside interoperability, Harrington Storz offers maximized water flow. For example, a five-inch Harrington Storz offers a four and a half inch waterway. Other special connections on the market only offer a four-inch waterway.
