The 4 in. PVC Long-Turn Elbow makes a 90° turn in 4 in. sewer and drain (S&D) pipe runs. The sweep elbow has a longer length than a standard elbow for less turbulence; and as a result, a smoother and more consistent flow. The 90° 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 drain fitting is made of polyvinyl chloride (PVC) for Hub X Hub solvent-weld connections. Meets applicable ASTM standards. For use in non-pressurized underground sewer and drainage applications; maximum working pressure of 5 psi. This elbow is used to make a change in direction in the pipeline and connects two pipes of the same type and diameter size.
