Our Sentinel 250™ Fire Hydrant will seem like an old friend when you see it, as well it should because it retains the popular features of our hydrants, such as the boltless attachment of the bonnet, and the simple 2-bolt traffic coupling. Even it's exterior appearance harkens to our hydrant's distinguished lineage. But look more closely and you'll find a number of performance enhancing improvements. Such as the nozzle area, with more generous smoother contours for better flow. And down underground, where the interior is also larger to better supply that flow, plus the main valve area has been beefed up for more reliable operation and easier maintenance. It's clearly the best U.S. Pipe® hydrant ever made. You'll find complete details and cutaway views of all that the Sentinel 250 hydrant has to offer in a full-color brochure in the 'Products/Fire Hydrants' area of this web site.
