Reducing Tee, Slip x Slip x Slip PVC Schedule 40 2" x 2" x 1-1/2" (401-251)

This 2" x 2" x 1-1/2" Schedule 40 PVC Reducing Tee (Slip x Slip x Slip) provides a three-way solvent-cement junction in which the perpendicular branch outlet steps down to 1-1/2" while both inline run ends maintain the full 2" mainline diameter — the most modest confirmed reduction in the 2" run inlet sub-series, tapping a near-full-size socket branch off a larger distribution main in an all-socket PVC assembly without reducing mainline flow through the run. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial installations where a corrosion-resistant, all solvent-cement near-full-size branch tap is required off a 2" socket distribution main at a single one-step nominal reduction.

The two 2" slip socket run ends form the inline portion of the tee and accept 2" PVC pipe for permanent solvent-cement bonds, maintaining full mainline diameter through the run without restriction or interruption. The 1-1/2" slip socket branch outlet accepts 1-1/2" PVC pipe for a permanent solvent-cement bond perpendicular to the run, providing a near-full-size socket branch connection that preserves very high flow capacity through the outlet — the largest branch outlet confirmed in the 2" run inlet 401 sub-series and appropriate for high-flow sub-main connections, large zone supply headers, and high-capacity equipment feed runs where the downstream 1-1/2" socket pipe run carries substantial flow off the 2" main. This all-slip configuration is the correct choice when the downstream 1-1/2" branch connection is a PVC socket pipe run that will be solvent-cemented throughout — it should not be confused with any 402 series mixed-connection counterpart at this size (Slip x Slip x FPT, if stocked), which would provide a 1-1/2" female-threaded branch outlet for connecting male NPT-threaded components directly off the tee without a separate adapter, or with the full-size 2" Tee (401-020 if stocked), which maintains full 2" diameter at all three ports rather than stepping the branch down. The 2" to 1-1/2" step-down is a 1.33:1 nominal reduction — the most minimal step-down available at this mainline diameter — driven entirely by downstream pipe sizing compatibility rather than any hydraulic flow management requirement, and most commonly encountered where a 1-1/2" socket sub-main, zone header, or equipment feed run must tap off a 2" socket distribution main while carrying near-full mainline flow capacity through the branch.

Rated to 280 psi at 73°F (governed by the 2" run ends), this tee is suited for standard commercial and light industrial pressure service. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal fittings in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to both the pipe end and fitting socket at each port per ASTM D2564 procedures, using a primer appropriate for the pipe and fitting schedule. Insert pipe fully into each socket and maintain a quarter-turn during assembly for even cement distribution across the joint surface. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Taps 1-1/2" socket high-flow zone supply sub-mains, large zone lateral headers, and distribution branch sub-mains off 2" socket mainline distribution runs in agricultural and municipal irrigation systems where the near-full-size 1-1/2" branch carries the highest flow volume of any confirmed branch outlet in the 2" run inlet sub-series — appropriate for large-zone supply and high-demand lateral applications
• Commercial Plumbing — Branches 1-1/2" socket supply sub-mains and high-flow equipment feed lines off 2" socket pressurized distribution mains in commercial building water systems where all-socket PVC construction is specified throughout and the branch outlet must carry near-full mainline flow to a high-demand downstream assembly or sub-distribution header
• Industrial Process Piping — Taps 1-1/2" socket high-capacity equipment feed runs, process water sub-main branches, and near-full-flow distribution laterals off 2" socket process water headers in water treatment, chemical processing, and manufacturing facilities where all-cemented Schedule 40 PVC construction is maintained throughout and near-full branch flow capacity is required at the tap point
• Chemical Handling — Provides a corrosion-resistant, all solvent-cement near-full-size branch tap in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, at chemical distribution sub-headers, high-capacity dosing line branches, and near-full-flow equipment feed laterals where a 1-1/2" socket pipe run must tap off a 2" socket distribution main in an all-cemented configuration
• Water Treatment & Aquaculture — Used at filter feed distribution branch points, recirculating system high-capacity sub-main taps, and treatment equipment feed connections where a 2" socket main must supply a 1-1/2" socket pipe run at near-full mainline flow capacity to a high-demand treatment component, pump feed header, or large-capacity distribution branch requiring NSF/ANSI 61 compliance and an all-cemented assembly throughout
• HVAC & Mechanical Systems — Taps 1-1/2" socket high-flow branch supply sub-mains and large-capacity equipment feed runs off 2" socket distribution headers on cooling tower supply assemblies, chilled water distribution systems, and chemically treated water mains within the Schedule 40 pressure class where all-socket construction is preferred and near-full branch flow capacity is required at the highest-demand tap points along the 2" main
