Robust ductile iron and PVC fittings designed to withstand the stresses of service in underground irrigation systems.
Conventional solvent-weld PVC fittings are prone to fail when subjected to the cyclical pressure surges that occur in golf course irrigation systems (and in other similar underground systems). But HARCO ductile iron fittings are extremely robust and are immune to the cracking, breaking, and blowouts that occur so often in PVC fittings.
HARCO’s deep socket bells keep PVC pipes captive while accommodating their contraction and expansion.
Proven in both laboratory testing and in decades of reliable service, HARCO products comply with major ASTM and AWWA performance standards.
