National Diversified Sales 41P0ST 4" White Hub x Spigot PVC S&D 90 Degree Long-Turn Street Elbow adds a 90° turn in Sewer and Drain (S&D) pipe runs. The street elbow differs from a standard elbow in that it has a Hub X Spigot connection rather than a Hub X Hub connection. The long turn feature allows the water to travel around the bend with less turbulence, resulting in a smoother and more consistent flow. The 90° Street Ell also connects to select drainage products compatible with 4 in. S&D connections such as channel drain outlets, Flo-Well® Dry Well System, drainage grates, and pop-up emitters. The 90° Long-Turn Street Elbow is made of polyvinyl chloride (PVC) and makes a Hub X Spt solvent-weld connection. Meets applicable ASTM standards. For use in non-pressurized underground sewer and drainage applications; maximum working pressure of 5 psi. Hassle-free limited lifetime warranty guarantees the NDS product is free from defects—or we’ll replace it.
