Eliminate Concrete Thrust Blocks
With HARCO fitting to pipe restraints as well as pipe to pipe restraints and valve restraints, underground gasketed piping can be installed without the use of concrete thrust blocks. Joint restraint is especially useful for bridge crossings, stream crossings, unstable soils, fill areas, and places where concrete thrust blocks are awkward.

One Size Fits All
The Harco Valve to Pipe restraint fits push-on valves for IPS-PVC pipe made by American Flow Control/Waterous, AVK, Clow, Kennedy, Matco-Norca, M&H and Nibco. New Design with fewer Parts HARCO’s Valve to Pipe Restraint now has fewer parts and allows for easier installation of the grip rings and ductile iron restraint rods from the side.

Proper Thrust Force Transfer
HARCO’s design transfers valve thrust forces directly to the grip rings unlike other valve restraints that apply forces to the ends of the pipe risking a failure. Harco grip rings have machined serration which have the exact form required to grip the pipe perfectly, ensuring long-term performance. As cast serrations provide inconsistent gripping of the pipe and questionable long-term performance.

The HARCO Difference
Standards and testing are a major advantage to HARCO. The grip ring design used by HARCO has been tested to comply with the industry standard for PVC pipe joint restraint, Uni-B-13-94, passing all three tests: the quick burst test, the 1,000 HR test and the one million cycle test.
