Tee, Slip x Slip x FPT PVC Schedule 40 2" (402-020)

This 2" Schedule 40 PVC Slip × Slip × FPT Tee provides a female-threaded branch outlet off a 2" solvent-cemented PVC run, combining permanent slip socket run ports with a 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 2" FPT branch outlet receives any compatible 2" male-threaded fitting, valve, nipple, or equipment connection at the branch position without additional adapters.

The mixed slip-and-thread construction is the defining characteristic of the 402-020 and the primary reason it is specified over a standard all-socket tee in the applications it serves. A fully solvent-welded Slip × Slip × Slip tee (401-series) at the same 2" size serves branch connections where the branch run is cemented PVC pipe throughout — correct wherever the branch continues as solvent-welded piping downstream of the tee. The 402-020 is the correct selection wherever the main run is solvent-welded PVC but the branch connection must interface with a male-threaded component — a threaded valve body, a threaded strainer, a pump port, a male-threaded nipple assembly, or any equipment connection presenting an MPT inlet at the branch position. The FPT branch receives these male-threaded components directly at the tee body, eliminating the need for a separate all-socket tee plus a downstream female adapter to accomplish the same result.

At 2", this mixed-connection configuration appears most frequently at primary distribution and process piping positions where the solvent-welded main run carries substantial flow volume and the branch connection must interface with a threaded valve, isolation component, instrument assembly, or equipment port. Commercial irrigation systems use the 402-020 at mainline positions where a threaded ball valve, gate valve, or flow control valve branches off the cemented 2" PVC main without requiring an adapter between the tee body and the valve inlet. Commercial plumbing and process systems use it wherever a threaded equipment connection, pump port, or valve body must branch off the cemented 2" distribution main at the tee position. At every such position where the run is cemented PVC and the branch is a threaded component, the 402-020 accomplishes both the branch connection and the thread-to-socket transition in a single fitting body.

Understanding the three available Schedule 40 tee configurations at 2" supports correct product selection. The 401-series all-socket tee serves fully cemented three-way branch connections where all three ends are PVC pipe. The 402-020 serves runs where both sides of the through-run are cemented PVC and the branch requires a female-threaded connection. Any all-threaded FPT × FPT × FPT equivalent at 2" serves fully threaded assemblies where all three connections are male-threaded nipples or fittings. When the run is solvent-welded and only the branch must be threaded, the 402-020 is the direct and correct selection.

The 402-020 is the Schedule 40 counterpart to the 802-series Schedule 80 Slip × Slip × FPT tees previously written in this catalog. Where the 802-series serves the same mixed-connection requirement in dark gray Schedule 80 PVC at higher pressure ratings, the 402-020 delivers the same functional configuration in white Schedule 40 PVC — correct for systems where the Schedule 40 pressure rating of 280 psi at 73°F is sufficient for the application.

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 in environments 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, 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 2" FPT branch before installing downstream threaded components. Hand-tighten plus one to two turns — do not over-torque PVC female threads. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Commercial & Municipal Irrigation — Taps a 2" female-threaded branch off a 2" solvent-cemented PVC mainline at valve station positions, filter station branch connections, and zone header assemblies in commercial, golf course, and agricultural irrigation systems — the defining application for the mixed-connection tee at 2" Schedule 40 where the cemented 2" mainline must interface with male-threaded gate valves, ball valves, and flow control valves at mainline branch positions without intermediate adapters between the tee body and the valve inlet
• Commercial Plumbing — Provides a 2" female-threaded branch off a solvent-welded 2" Schedule 40 PVC water supply main at valve connections, pressure gauge assemblies, equipment supply branches, and backflow preventer inlet connections in commercial building water distribution systems where the through-run is cemented PVC pipe and the branch must connect to a male-threaded valve or equipment component
• Pool, Spa & Aquaculture — Taps a 2" female-threaded branch off a solvent-cemented 2" PVC recirculation main, filtration header, or backwash line at pump connection ports, valve body branches, filter head inlet connections, and multiport valve connections in commercial pool, spa, and aquatic facility installations where the cemented main must interface with male-threaded equipment components at the branch position
• Water & Wastewater Treatment — Installs a 2" female-threaded branch off a solvent-welded 2" Schedule 40 PVC process header at valve connections, pump discharge branch positions, sampling valve ports, chemical dosing valve connections, and instrument isolation branches in municipal and industrial water treatment facilities where the through-run continues as cemented PVC and the branch connects to a male-threaded process component
• Industrial Process Piping — Provides a 2" FPT branch off a solvent-welded 2" Schedule 40 PVC process distribution header at threaded valve connections, strainer body branches, equipment nozzle connections, and instrument isolation positions in light industrial and chemical handling systems where the cemented PVC run must interface with male-threaded process equipment at the branch fitting position
• Pump Station & Equipment Connection Assemblies — Taps a 2" male-threaded pump discharge port, strainer inlet, or equipment MPT connection off a solvent-cemented 2" Schedule 40 PVC distribution main at pump station outlet assemblies, equipment connection positions, and mechanical equipment pad piping where the branch must receive the equipment's male-threaded inlet directly at the tee body without an intermediate female adapter fitting
• Site Utilities & Above-Grade Distribution — Provides a 2" female-threaded branch off solvent-welded 2" Schedule 40 PVC above-grade utility water distribution mains, backflow preventer inlet connections, and service valve connection positions in commercial site development where the cemented pipe run must interface with male-threaded utility components and isolation valve bodies at branch positions throughout the site distribution layout
