The MUELLER STREAMLINE 5984 is a 1-1/2 inch PVC DWV street elbow with a 22.5-degree angle, designed for drain, waste, and vent piping systems. It connects via a spigot on one end and a hub on the other, allowing it to mate directly into a fitting socket without a separate coupling. The PVC construction meets ASTM D2665, F1498, D331, and D1784 material specifications and carries NSF 14 and UPC certification. Plumbers install this fitting in residential and commercial gravity-flow drainage systems where a shallow directional change is required. Smooth interior walls minimize flow restriction and resist scale buildup over time.
This elbow is suited for industrial, sanitary, and chemical-drainage applications where resistance to corrosion and common drain-line chemicals is a priority. The street configuration is particularly useful in tight-clearance installations where eliminating an extra coupling simplifies the run. Standard dimensional tolerances ensure consistent fitment with other NSF 14 and UPC-listed PVC DWV components from compatible manufacturers.
Designed as an OEM-style replacement and new-installation fitting for 1-1/2 inch PVC DWV piping systems meeting NSF 14 and UPC standards in drain, waste, vent, and sanitary applications.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off all flow and verify the line is depressurized before cutting into an existing drain run. Solvent-weld both connections using PVC primer and cement rated for DWV service, following the cement manufacturer's cure time before restoring flow. Do not apply flame heat to PVC fittings.
