The TIGRE USA INC 36-678 is a 6-inch PVC 90-degree long turn sanitary elbow designed for sewer and drain piping systems. Also referred to as a quarter bend, this fitting redirects flow direction within a drainage line while maintaining smooth, unobstructed flow through the long-radius sweep. The fitting is manufactured from PVC, making it resistant to corrosion and chemical degradation common in drain and waste applications. Licensed plumbers and pipefitters install this elbow in residential and commercial drain, waste, and vent systems where a 90-degree direction change is required.
This fitting is used in sewer and drain piping applications where flow must change direction by 90 degrees. The long turn design reduces turbulence and minimizes the risk of clogging compared to short-radius elbows, making it well suited for gravity-fed horizontal drain runs and vertical stack transitions. It is a standard fitting choice in both new construction and retrofit plumbing projects involving 6-inch diameter drain lines.
Designed as an OEM-style replacement and standard fitting for 6-inch PVC sewer and drain piping systems in residential and commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code. Shut off water supply and isolate the section of drain line before beginning work. PVC solvent cement and primer are typically required to secure socket-end connections. Ensure proper slope and support of horizontal drain runs per code requirements after fitting installation.
