About HARCO
HARCO (The Harrington Corporation) manufactures ductile iron and PVC fittings for water distribution and large-diameter irrigation mainlines, where joints have to be restrained against thrust rather than relying on the pipe itself.
Our HARCO range includes ductile iron valve-to-pipe restraints in 6 in., used to lock a valve to the mainline so line pressure cannot push the joint apart.
