Harco - 4" 11-1/4° Ductile Iron IPS Elbow - Gskt X Gskt

Fittings Designed for Ductility and Reliability
Harco’s DI push-on joint fittings offer balance of strength, ductility, impact, and corrosion resistance. Fittings are manufactured for ASTM A536, Grade 65-45-12 ductile iron with a tensile strength of 65,000 PSI. These fittings are designed for use on IPS PVC pipe and steel pipe in underground water mains, irrigation systems, and sewer force mains.

Harco fittings are pressure rated at 350 PSI. They are cast of ductile iron with 65,000 PSI tensile strength and a wall thickness of 0.31". This high strength capacity is vital in withstanding the critical cyclical surges and high mechanical stresses present in golf course irrigation systems. This high strength is especially important on systems utilizing the new computer controllers which can create additional surge pressures.

In ductile and cast iron, corrosion resistance is created from a layer of insoluble graphite that is formed from initial corrosion that becomes a protective barrier against additional corrosion attack. This phenomenon is the reason that ductile iron and cast iron has such longevity in direct bury application in the majority of soils.

Deep Bells with Gasketed Joints Simplify Installation and Eliminate Problems
Harco’s push-on joint design provides for a deep socket bell to accommodate the expansion and contraction of a PVC piping system. The design incorporates a massive gasket in a square groove to prevent roll out and fish mouths. All fittings are designed to work directly on IPS size pipes — without the problems of using transition gaskets.
The push-on joint allows easy, all-weather installation for bottletype joints every time. The joint assembles exactly like the pipe joints, eliminating all the potential errors that solvent cement voids, incorrect procedures, and inclement weather can cause.
