The MUELLER STREAMLINE ABSBEND18SPH6 is a 6-inch ABS DWV 45-degree street elbow configured with a spigot by hub (Spg x H) end pattern. This plastic drainage fitting redirects flow at a 45-degree angle within drain, waste, and vent piping systems. The spigot end inserts directly into another fitting hub, eliminating the need for an additional coupling and reducing the total number of joints in the run. Plumbers and pipefitters install this type of fitting in residential and light commercial DWV systems where smooth directional changes and leak-free solvent-welded connections are required.
This street elbow is suited for use in gravity-flow drain and vent piping, including branch drain lines, vertical stack offsets, and fixture drain connections. The 45-degree bend produces a gradual change in direction that supports proper drainage flow compared to sharper 90-degree bends. The spigot x hub configuration makes it adaptable to back-to-back fitting assemblies and close-quarter installations where pipe stubs would add unnecessary length to the assembly.
Designed as an OEM-style replacement and new-construction fitting for 6-inch ABS DWV piping systems following standard hub and spigot dimensions.
Installation must be performed by a licensed plumber in jurisdictions where plumbing permits are required. Shut off water service and confirm the drain line is clear before beginning work. Clean and dry all mating surfaces before applying ABS solvent cement, and follow the cement manufacturer's cure time before returning the system to service. Work must conform to applicable local plumbing codes and the International Plumbing Code (IPC) where adopted.
