Reducing Tee, Slip x Slip x Slip PVC Schedule 80 6" x 6" x 3" (801-530)

The 6" x 6" x 3" PVC Schedule 80 Reducing Tee (Slip x Slip x Slip) is a heavy-duty thermoplastic tee fitting designed for industrial piping systems that require a smaller branch takeoff from a larger main run. With 6-inch slip socket connections on both run ends and a 3-inch slip socket on the branch outlet, this fitting taps a 3-inch lateral from a 6-inch main — all three connections installing permanently via PVC solvent cement for a pressure-tight, full-bore assembly throughout the run and branch.

The reducing tee is one of the most frequently specified fittings in industrial and commercial PVC systems precisely because most real-world piping networks are not uniform in diameter. A primary distribution main or process header typically operates at a larger diameter to handle total system flow, while individual branch lines serving equipment, zones, or sub-processes step down to smaller sizes appropriate for their localized demand. The 6" x 6" x 3" configuration reflects this logic directly — the 6-inch run maintains the capacity of the main, while the 3-inch branch delivers flow to a downstream subsystem at a size matched to that subsystem's requirements rather than the full header volume.

All three slip socket connections are sized for Schedule 80 PVC pipe and are designed for solvent cement installation per ASTM D2564 procedures. Schedule 80 PVC provides the elevated wall thickness, higher pressure ratings, and greater mechanical strength required in chemical processing, water treatment, and other demanding industrial environments where Schedule 40 fittings are not specified. The additional wall thickness at the branch hub is particularly relevant in reducing tees, where the geometry of the branch intersection introduces stress concentrations that benefit from the heavier Schedule 80 wall section. Manufactured to ASTM D2467 standards and fully compatible with Schedule 80 PVC pipe in both 6-inch and 3-inch sizes.

Industries & Applications:

• Industrial Process Piping — The primary application for a 6" x 3" reducing tee in Schedule 80; used in process headers and distribution mains where a 3-inch lateral branches off to serve individual equipment connections, chemical feed points, or subsystem supply lines
• Chemical Processing & Handling — Specified in chemical-resistant PVC conveyance systems where a 6-inch main requires a 3-inch branch takeoff for dosing lines, transfer connections, or process sub-feeds in applications involving acids, bases, or industrial solvents compatible with PVC
• Water & Wastewater Treatment — Applied in treatment plant process piping where 6-inch mains serve as primary distribution headers and 3-inch branches supply individual treatment stages, filter units, chemical injection points, or monitoring stations
• Pump Systems & Pressure Headers — Used in pump discharge headers and pressure distribution manifolds where multiple 3-inch branch lines serve downstream zones or equipment from a common 6-inch supply main
• Irrigation & Agricultural Infrastructure — Incorporated in large commercial and agricultural irrigation systems where a 6-inch primary main requires a 3-inch branch for a zone valve assembly, filter station, or submain connection serving a discrete irrigation block
• Municipal Infrastructure & Industrial Facilities — Specified in pump station piping, lift station headers, and industrial facility process mains where a heavy-duty, chemical-resistant reducing tee is required at a branch takeoff point that will see elevated pressure or demanding service conditions
