Reducing Tee, Slip x Slip x Slip PVC Schedule 40 2" x 2" x 1/2" (401-247)

This 2" x 2" x 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 1/2" while both inline run ends maintain the full 2" mainline diameter — a significant 4:1 nominal reduction that taps a small-bore socket service line off a large 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 small-bore branch tap is required off a 2" socket distribution main at the most aggressive confirmed reduction in the 2" run inlet sub-series.

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 1/2" slip socket branch outlet accepts 1/2" PVC pipe for a permanent solvent-cement bond perpendicular to the run, providing a very small-bore socket tap point that serves dedicated instrument supply stubs, pressure monitoring connection lines, chemical injection feed runs, micro-flow service laterals, and small-bore distribution connections branching off the 2" main. This all-slip configuration is the correct choice when the downstream 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 1/2" female-threaded branch outlet for connecting male NPT-threaded components directly off the tee without a separate adapter. The 2" to 1/2" step-down is the most aggressive confirmed reduction in the 2" run inlet 401 sub-series — more so than the 401-248 (2" x 3/4" branch) — and is most commonly encountered where dedicated very-small-bore socket service runs must branch off a large 2" distribution main while maintaining full mainline flow capacity through the run; this configuration is the all-socket parallel to the 401-209 (1-1/2" x 1/2" branch) at the larger 2" mainline diameter.

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 1/2" socket instrument supply stubs, pressure monitoring connection lines, and dedicated micro-flow lateral connections off 2" socket distribution mainlines in agricultural and municipal irrigation systems where the 2" main must maintain full flow capacity at each tap point while supplying very-small-bore socket service connections along the run
• Commercial Plumbing — Branches 1/2" socket supply lines to pressure gauge feed stubs, dedicated instrument connections, and very-small-bore service branches off 2" socket pressurized distribution mains in commercial building water systems where all-socket PVC construction is specified throughout and the 1/2" branch serves a dedicated instrument or micro-flow service connection rather than a zone supply or full-flow branch run
• Industrial Process Piping — Taps 1/2" socket instrument supply lines, chemical injection feed stubs, sampling point connections, and micro-flow process water branches off 2" socket process water distribution headers in water treatment, chemical processing, and manufacturing facilities where all-cemented Schedule 40 PVC construction is maintained throughout the branch tap assembly and the 2" mainline must remain uninterrupted at each tap point
• Chemical Handling — Provides a corrosion-resistant, all solvent-cement very-small-bore branch tap in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, particularly at chemical injection feed stubs, micro-flow dosing line connections, and sampling tap feeds where a 1/2" socket pipe run must branch off a 2" socket distribution main in an all-cemented configuration without any threaded interface at the tee
• Water Treatment & Aquaculture — Used at instrument supply branch stubs, chemical dosing micro-flow laterals, and small-bore monitoring connection feeds where a 2" socket main must supply a 1/2" socket pipe run to a pressure monitoring point, micro-flow treatment component, or sampling instrument requiring NSF/ANSI 61 compliance and an all-cemented assembly throughout
• HVAC & Mechanical Systems — Taps 1/2" socket instrument supply stubs and micro-flow service laterals 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 very-small-bore branch taps are required at instrument connection points along the 2" run
