Reducing Tee, Slip x Slip x FPT PVC Schedule 40 2" x 3/4" (402-248)

This 2" × 3/4" 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 3/4" 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 3/4" FPT branch outlet receives any compatible 3/4" male-threaded fitting, valve, nipple, or equipment connection at the branch position without additional adapters or reducing components at the branch face.

The 402-248 distinguishes itself from its 402-series sibling the 402-020 (2" × 2" × 2" equal tee) along two dimensions simultaneously. The first is branch size: where the 402-020 equal tee presents a full-size 2" FPT branch outlet — the correct selection wherever the branch must carry the same capacity as the 2" run — the 402-248 presents a reducing 3/4" FPT branch outlet, correct wherever the branch requires a smaller-diameter threaded connection off the 2" main. When the downstream component at the branch is a 3/4" male-threaded valve, nipple, flow control fitting, pressure gauge, or instrument component rather than a full-size 2" threaded element, the 402-248 is the direct, single-fitting solution at the branch position.

The second dimension is the reducing configuration itself. Achieving the same result without the 402-248 would require an equal-size 2" Slip × Slip × FPT tee (402-020) plus a 2"-to-3/4" reducing bushing at the branch outlet — two fittings, two additional connections, and added axial length at the branch position. The 402-248 accomplishes the full-size 2" run continuity, the slip-to-thread branch transition, and the 2"-to-3/4" branch size reduction in a single fitting body, eliminating the intermediate reducing bushing and keeping the branch connection as compact as the tee body itself. In irrigation systems, commercial plumbing assemblies, and process piping layouts where branch fitting count minimization and compact assembly are practical objectives, this single-fitting efficiency is a meaningful advantage.

The 3/4" FPT branch outlet is particularly well suited for the specific downstream components that most commonly branch off 2" Schedule 40 PVC mains in irrigation, commercial plumbing, and light industrial systems. Three-quarter inch NPT is a standard connection size for manual and automatic ball valves, gate valves, globe valves, chemical injection connections, pressure gauges, flow control fittings, fertilizer injectors, and small equipment connections throughout these system types. Wherever the 2" PVC mainline must supply any of these 3/4"-ported components, the 402-248 bridges the run-to-branch size transition and the socket-to-thread interface simultaneously at the tee body.

The mixed slip-and-thread construction integrates the 402-248 at the boundary between the solvent-welded PVC main run and the threaded branch assembly. Both 2" run port joints are permanent, chemically fused solvent-cemented connections that become integral to the pipe system once cured. The 3/4" FPT branch accepts male-threaded components with PTFE tape and thread sealant — a connection that can be removed and replaced without cutting into the cemented pipe system, providing the inherent serviceability advantage of a threaded branch at a position that must remain accessible for valve replacement, system modification, or branch commissioning.

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 temperature and humidity guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to all male threads engaging the 3/4" 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 3/4" female-threaded branch off a 2" solvent-cemented Schedule 40 PVC mainline or submain at valve station positions where 3/4" MPT-ported ball valves, gate valves, or flow control valves must branch off the 2" main — the defining application for the reducing 402-248 vs. the equal 402-020; eliminates the separate reducing bushing that an equal 2" FPT tee would require at the valve connection
• Irrigation System Chemical Injection & Fertigation — Provides a 3/4" female-threaded branch connection off a 2" solvent-welded Schedule 40 PVC irrigation main at chemical injection points, fertigation injector connections, and flow meter branches where the downstream injection or metering component presents a 3/4" MPT inlet and the 2" main run continues through the tee without size reduction
• Commercial Plumbing — Provides a reducing 3/4" female-threaded branch off a 2" solvent-welded Schedule 40 PVC water supply main at pressure gauge tap positions, shutoff valve connections, equipment supply branch points, and backflow preventer test cock connections in commercial building water distribution systems where the branch component is 3/4" NPT and the 2" main continues at full size through the tee
• Pool, Spa & Aquaculture — Taps a 3/4" female-threaded branch off a 2" solvent-cemented Schedule 40 PVC recirculation main or equipment header at chemical feed connections, small valve branches, pressure gauge ports, and small equipment connections in commercial pool, spa, and aquatic facility installations where 3/4" MPT-ported components must branch off the 2" primary distribution piping
• Water & Wastewater Treatment — Installs a reducing 3/4" FPT branch off a 2" solvent-welded Schedule 40 PVC distribution header at sampling valve connections, chemical dosing branch positions, pressure gauge taps, and instrument isolation branches in municipal and industrial water treatment facilities where the branch component is 3/4" NPT and the 2" main continues through the tee at full capacity
• Light Industrial Process Piping — Provides a reducing 3/4" female-threaded branch off a 2" solvent-welded Schedule 40 PVC process distribution header at chemical injection points, process valve connections, flow meter branches, and small equipment connections where the 3/4" MPT-ported branch component interfaces with a 2" cemented main — eliminating the equal FPT tee-plus-reducing-bushing assembly in a single fitting
• Site Utilities & Distribution — Taps a 3/4" female-threaded branch connection off a 2" solvent-welded Schedule 40 PVC site utility water distribution main at hose bib valve connections, small equipment feed branches, and secondary supply takeoffs where the branch component presents a 3/4" MPT inlet and the 2" main continues at full size through the tee body
