Tee, Slip x Slip x FPT PVC Schedule 40 3/4" (402-007)

This 3/4" Schedule 40 PVC Tee (Slip x Slip x FPT) provides a three-way mixed-connection junction at the dominant residential and light commercial irrigation system diameter — accepting 3/4" PVC pipe at both inline run ends for permanent solvent-cement bonds while providing a built-in 3/4" female NPT-threaded branch outlet for a direct male-threaded component connection perpendicular to the run. Constructed in white Schedule 40 PVC, it is the standard mixed-connection tee for applications where a 3/4" all-socket pipe run must simultaneously tee off to a 3/4" male-threaded valve body, solenoid valve inlet, zone valve, filter housing, or threaded service component at the branch location without a separate female adapter or thread-transition fitting at the branch port.

The two 3/4" slip socket run ends accept 3/4" PVC pipe for permanent solvent-cement bonds forming the continuous inline run, while the 3/4" FPT branch outlet accepts any standard 3/4" male NPT-threaded fitting, solenoid valve inlet, zone valve body, ball valve, filter housing connection, pump port, or service component for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The built-in FPT branch eliminates the need for a separate female adapter at the branch port of a standard all-slip tee — reducing fitting count, shortening assembly time, and minimizing the assembly footprint at every mixed-connection branch tap throughout the distribution grid. At 3/4", this tee is among the highest-demand entries in the 402 series — the 3/4" Slip x Slip x FPT configuration appears throughout residential and light commercial irrigation valve station manifold assemblies where a 3/4" socket pipe run feeds a valve box and the branch must accept the male-threaded inlet of a solenoid valve, gate valve, or zone control valve directly; in commercial plumbing socket distribution assemblies where a 3/4" socket main must simultaneously continue the run and serve a 3/4" male-threaded branch service component; and in pump station assemblies where a 3/4" socket suction or discharge run must incorporate a male-threaded gauge, valve, or instrument connection at the branch. This configuration should not be confused with the full-size all-slip 401-007 (if stocked), which provides a 3/4" socket branch outlet for a continuing cemented pipe run rather than a female-threaded branch for a male-threaded component, or with the reducing 402 series variants at adjacent sizes confirmed in this catalog session.

Rated to approximately 480 psi at 73°F, 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. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to both the pipe end and fitting socket at each run 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. On the 3/4" FPT branch, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating component before engagement. Avoid over-torquing the mating male threaded component — PVC female threads require hand-tight plus one to two turns. Allow adequate cure time on the cemented joints before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Provides the standard mixed-connection branch junction at 3/4" valve box manifold entries, irrigation mainline tee-off points, and zone supply line branch connections in residential and light commercial irrigation systems where a 3/4" socket pipe run must simultaneously continue the inline run and supply a 3/4" male-threaded solenoid valve inlet, zone valve body, filter housing connection, or valve station manifold port without a separate female adapter at the branch location
• Commercial Plumbing — Distributes water from a 3/4" socket distribution main to a 3/4" male-threaded branch service valve, pressure gauge connection, backflow preventer port, or equipment feed connection in commercial building water distribution systems where the socket main run must continue while simultaneously providing a female-threaded branch receptacle for a male-threaded service component at the tee junction
• Pump Station Assemblies — Incorporates 3/4" male-threaded pressure gauge connections, instrument ports, solenoid valve inlets, and service branch components directly at 3/4" socket pump suction approach runs, discharge headers, and valve cluster socket pipe runs in pump station installations where the mixed-connection tee eliminates a separate socket tee plus female adapter at each instrumented or valved branch location
• Industrial Process Piping — Provides a standard mixed-connection three-way junction on 3/4" socket process water distribution runs, chemical feed lines, and service manifold assemblies in water treatment, chemical processing, and manufacturing facilities where a 3/4" male-threaded valve body, instrument connection, or equipment port must be served directly off a 3/4" socket pipe run at the inline branch tap point
• Water Treatment & Aquaculture — Used at inline branch tap points along 3/4" all-socket distribution runs where a 3/4" male-threaded chemical dosing connection, filter housing port, instrument tap, or treatment equipment inlet must be served directly off the socket pipe run with NSF/ANSI 61 compliance required throughout the mixed-connection assembly
• HVAC & Mechanical Systems — Provides mixed-connection branch junctions on 3/4" socket cooling tower supply headers, chilled water distribution branch lines, and chemically treated water system service assemblies within the Schedule 40 pressure class where 3/4" male-threaded valve bodies, instrument connections, and service components must be served at inline branch tap points along the all-socket pipe run
