Reducing Tee, Slip x Slip x FPT PVC Schedule 40 2" x 2" x 1" (402-249)

This 2" × 1" Schedule 40 PVC Reducing Tee provides the shallowest available female-threaded reducing branch off a 2" solvent-cemented PVC run, combining permanent 2" slip socket run ports with a reducing 1" female NPT threaded branch connection in a single fitting. The two 2" slip socket run ports accept standard 2" PVC pipe for solvent cement joining along the through-run, while the 1" FPT branch outlet receives any compatible 1" male-threaded fitting, valve, strainer, pump port, flow meter, or equipment connection at the branch position without additional adapters or reducing components at the branch face.

Within the 402-series 2" run sub-group, the 402-249 makes the minimal adjacent-size reduction at the branch — a single pipe size step from the 2" run down to a 1" FPT branch outlet. This shallowest-reduction positioning distinguishes it from all three sibling entries: the 402-020 equal tee (2" FPT branch matching the run), the 402-248 two-step reducing tee (3/4" FPT branch), and the 402-247 three-step reducing tee (1/2" FPT branch). Selecting among the four entries requires only identifying the NPT port size of the downstream branch component: a 2" MPT inlet calls for the 402-020; a 3/4" MPT inlet calls for the 402-248; a 1/2" MPT inlet calls for the 402-247; and a 1" MPT inlet — the most common of all four downstream sizes given the prevalence of 1" NPT across standard commercial and industrial valves and equipment — calls for the 402-249.

The 1" FPT branch outlet is what gives the 402-249 the broadest downstream application reach of the three reducing variants in this sub-group. One-inch NPT is among the most prevalent threaded connection sizes across the full range of standard commercial and industrial piping components — standard ball valves, gate valves, check valves, strainer bodies, pump discharge and suction ports, flow meters, and equipment nozzles are routinely manufactured at 1" NPT. Wherever a 2" Schedule 40 PVC mainline must supply any of these 1"-ported components at a branch position, the 402-249 bridges the one-step run-to-branch size reduction and the socket-to-thread interface simultaneously at the tee body — without the intermediate reducing bushing or second tee that an equal 2" FPT tee would require to achieve the same 1" branch connection.

The one-step reduction geometry of the 402-249 also produces the smoothest hydraulic branch transition of the three reducing variants. The minimal size differential between the 2" run and the 1" branch minimizes the abruptness of the flow area change at the branch entry point — an advantage in pump suction branch connections, flow-metering branches, and other flow-sensitive positions where the hydraulic quality of the branch junction matters alongside the practical fitting selection.

As with all 402-series mixed-connection fittings, the slip run ports form permanent solvent-cemented joints with the 2" PVC main while the FPT branch retains the inherent serviceability of a threaded connection. The branch component can be removed and replaced without cutting into the cemented pipe system, preserving access at valve bodies, pump connections, strainer inlets, and equipment ports for routine service, seasonal maintenance, and component replacement throughout the life of the installation.

Manufactured in white Schedule 40 PVC, this tee delivers reliable performance across commercial, light industrial, and residential piping applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life where metal tees would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F (governed by the 2" slip run ports), this fitting handles standard pressure service across irrigation, commercial plumbing, pool and spa, water treatment, and light industrial applications at 2". For the slip socket run ports, clean and dry both pipe ends and socket interiors before application. Apply purple PVC primer to all mating surfaces, then apply a uniform coat of medium-body Schedule 40 PVC solvent cement to both the pipe end and socket interior at each run port joint before inserting. Insert each pipe with a slight quarter-turn twist and hold firmly for 30 seconds. Stagger the two run port joints where possible and allow full cure time per the cement manufacturer's guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to all male threads engaging the 1" FPT branch before installing downstream components. Hand-tighten plus one to two turns — do not over-torque PVC female threads at the branch. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Commercial & Municipal Irrigation — Taps a reducing 1" female-threaded branch off a 2" solvent-cemented Schedule 40 PVC mainline or submain at valve station positions where 1" MPT-ported ball valves, gate valves, flow control valves, strainer inlets, and backflow preventer connections must branch off the 2" main — the defining and highest-frequency application for the 402-249 given the prevalence of 1" NPT-ported irrigation control components throughout commercial and agricultural irrigation systems
• Pump & Equipment Branch Connections — Provides a 1" female-threaded branch off a 2" solvent-cemented Schedule 40 PVC main at pump discharge port connections, strainer body branches, flow meter inlets, and equipment nozzle connections in commercial irrigation, pump station outlet assemblies, and mechanical equipment connection piping where the 1"-ported equipment component must branch off the 2" cemented main without an intermediate adapter at the tee face
• Commercial Plumbing — Taps a reducing 1" female-threaded branch off a 2" solvent-welded Schedule 40 PVC water supply main at shutoff valve connections, pressure gauge assemblies, equipment supply branch points, backflow preventer inlets, and fixture supply manifold connections in commercial building water distribution systems where the 1" MPT-ported branch component interfaces with the 2" cemented main at a single fitting position
• Pool, Spa & Aquaculture — Provides a 1" female-threaded branch off a 2" solvent-cemented Schedule 40 PVC recirculation main, filtration header, or equipment distribution piping at pump connection branches, filter head inlet ports, multiport valve connections, and large equipment supply positions in commercial pool, spa, and aquatic facility installations where 1" NPT-ported components must interface with the 2" primary piping
• Water & Wastewater Treatment — Installs a reducing 1" FPT branch off a 2" solvent-welded Schedule 40 PVC process distribution header at pump discharge connections, strainer body branches, flow meter positions, chemical dosing valve connections, and isolation valve branches in municipal and industrial water treatment facilities where the 1" MPT-ported downstream component interfaces with the 2" cemented distribution main
