Reducing Tee, Slip x Slip x FPT PVC Schedule 40 2" x 2" x 1/2" (402-247)

This 2" × 1/2" Schedule 40 PVC Reducing Tee provides a reducing female-threaded branch outlet off a 2" solvent-cemented PVC run, combining permanent 2" slip socket run ports with a reducing 1/2" 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 1/2" FPT branch outlet receives any compatible 1/2" male-threaded fitting, valve, dosing pump outlet, nipple, or instrument connection at the branch position without additional adapters or reducing components at the branch face.

Within the 402-series 2" run sub-group, the 402-247 makes a two-step reduction at the branch — from the 2" run size down to a 1/2" FPT branch outlet. This distinguishes it from both the 402-020 (equal tee, 2" FPT branch matching the run size) and the 402-248 (one-step reducing tee, 3/4" FPT branch). Selecting correctly among the three requires identifying the NPT port size of the downstream branch component. When the branch component presents a 2" male-threaded inlet, the 402-020 equal tee applies. When the branch presents a 3/4" male-threaded inlet, the 402-248 one-step reducing tee applies. When the branch component presents a 1/2" male-threaded inlet — the most common outlet size on chemical dosing pumps, metering valves, pressure gauges, flow switches, solenoid valves, and small control components throughout standard irrigation, plumbing, and process systems — the 402-247 is the direct and correct selection.

The 1/2" FPT branch outlet is what defines this fitting's primary application niche. One-half inch NPT is the standard connection size for chemical dosing and metering equipment, pressure gauges at standard ranges, small solenoid valve bodies, flow switches, level switches, and small equipment nozzles throughout commercial irrigation, commercial plumbing, and light industrial systems. Wherever a 2" Schedule 40 PVC mainline must supply or monitor through a 1/2" NPT-ported component, the 402-247 resolves the run-to-branch size transition and the socket-to-thread interface simultaneously at the tee body — eliminating the equal FPT tee-plus-reducing-bushing assembly that would otherwise be required to achieve the same connection in two fittings.

The two-step reduction from 2" to 1/2" is the deepest branch reduction in the 402-series 2" run sub-group written to date, and the 1/2" branch's strong association with chemical dosing and metering equipment makes this one of the most application-specific entries in the series. In irrigation fertigation systems where a chemical injector's 1/2" MPT outlet must branch off the 2" PVC mainline without size-reducing the main flow, in commercial plumbing systems where a 1/2" pressure gauge or test cock must be installed at a 2" distribution main, and in water treatment systems where a 1/2" dosing valve or sampling connection branches off a 2" process header, the 402-247 is the single-fitting solution that avoids the alternative two-fitting approach of a full-size 2" FPT tee plus a 2"-to-1/2" reducing bushing at the branch outlet.

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 for seasonal equipment changes, component replacement, and system modifications at the branch position.

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 1/2" 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:

• Chemical Dosing & Fertigation Systems — The defining application for the 2" × 1/2" reducing mixed-connection tee: taps a 1/2" female-threaded branch off a 2" solvent-cemented Schedule 40 PVC irrigation or process main at chemical injector outlet positions, fertigation dosing pump connections, and chemical metering equipment branches where the downstream dosing or metering component presents a 1/2" MPT outlet — eliminating the equal 2" FPT tee-plus-reducing-bushing assembly in a single compact fitting at the mainline branch position
• Commercial & Municipal Irrigation — Provides a 1/2" female-threaded branch off a 2" solvent-welded Schedule 40 PVC mainline or submain at pressure gauge tap positions, flow switch connections, small valve branches, and irrigation system monitoring instrument connections in commercial, golf course, and agricultural irrigation systems where the branch component is 1/2" NPT and the 2" main run continues at full capacity through the tee
