Tee, Slip x Slip x FPT PVC Schedule 80 3" x 1" (802-335)

The 3" x 3" x 1" PVC Schedule 80 Reducing Tee (Slip x Slip x FPT) delivers three functions in a single pressure-rated fitting — maintaining full 3" run diameter through both solvent-weld slip ends while providing a reduced 1" female-threaded branch port for connecting directly to a threaded valve, instrument, gauge, equipment inlet, or branch line adapter. By combining a full-bore solvent-weld run with a reducing threaded branch in one body, the 802-335 eliminates the need for a separate full-size tee, reducer bushing, and threaded adapter at the branch takeoff — reducing fitting count, minimizing potential leak points, and keeping the branch assembly compact.

The contrast between the 3" run and the 1" branch makes this a fitting well-suited for systems where a large-diameter primary line serves as a distribution header feeding smaller threaded branch connections — pressure gauge ports, chemical dosing inlets, drain taps, instrument connections, and small-diameter secondary service lines being the most common examples. The 1" FPT branch accepts any standard 1" MPT fitting or threaded component, providing broad compatibility with valves, adapters, and instruments across the NPT threaded fitting ecosystem.

Manufactured to ASTM D2467 standards and listed under NSF/ANSI 14, this fitting is molded from dark gray Schedule 80 PVC compound, delivering the greater wall thickness, elevated pressure ratings, and broad chemical resistance that Schedule 80 specifications demand. At 3" run size, this tee is most commonly found in commercial mechanical systems, industrial process piping, pump station headers, and chemical distribution infrastructure rather than in typical residential applications.

Specifications:

Industries & Applications:

• Pump Systems & Mechanical Rooms — Installed in 3" pump discharge or suction headers where the main run must pass through at full bore while branching to a 1" threaded pressure gauge port, relief valve connection, or auxiliary equipment inlet without disrupting flow through the primary run
• Chemical Processing — Used in large-diameter chemical distribution headers where a 3" solvent-welded supply line must feed a 1" threaded dosing port, sampling tap, or secondary chemical feed line in environments requiring PVC's broad resistance to acids, bases, and aggressive industrial fluids
• Industrial Manufacturing — Applied in process piping manifolds where a full-bore 3" run serves as a primary distribution line and a 1" threaded branch provides a compact, accessible connection point for instruments, drain valves, or secondary process lines without requiring additional transition fittings
• Municipal Water & Wastewater — Installed in pump station headers, treatment facility process lines, and distribution infrastructure where a 3" Schedule 80 main requires a reduced 1" threaded branch to instrumentation, sampling connections, chemical dosing inlets, or smaller service lines
• Commercial Plumbing — Used in mechanical room service headers and large-diameter building piping where a 3" solvent-welded run must branch to a 1" threaded connection for a pressure gauge, drain tap, or small-diameter equipment service line
• Irrigation & Agricultural — Applied at pump discharge assemblies and filter station headers where a 3" mainline must branch to a 1" threaded chemical injector port, air release valve, or pressure monitoring connection in large-scale commercial irrigation infrastructure
• Aquaculture & Water Treatment — Suits recirculating system distribution headers where a 3" solvent-welded supply line feeds 1" threaded branch connections to treatment equipment inlets, dosing ports, or monitoring instrumentation across multi-stage filtration and treatment systems
