The NIBCO 2 in. ABS DWV 60-Degree Hub x Hub Elbow is built for use with DWV systems to help remove wastewater from plumbing fixtures. The fitting features an ABS construction. Be sure, though, never to use a primer on ABS. ABS DWV is joined by solvent cementing or threading and can easily be connected to steel, copper, or cast iron through the use of transition fittings. Color: White.
