Tee, Slip x Slip x FPT PVC Schedule 40 1/2" (402-005)

This 1/2" Schedule 40 PVC Tee (Slip x Slip x FPT) provides a three-way mixed-connection junction at the standard small-bore service and instrument assembly diameter — accepting 1/2" PVC pipe at both inline run ends for permanent solvent-cement bonds while providing a built-in 1/2" 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 highest-pressure confirmed entry in the 402 series at 1/2" — carrying approximately 600 psi at 73°F — and the standard mixed-connection tee for applications where a 1/2" all-socket pipe run must simultaneously tee off to a 1/2" male-threaded valve body, solenoid valve inlet, instrument connection, chemical injection port, or threaded service component at the branch location without a separate female adapter or thread-transition fitting at the branch port.

The two 1/2" slip socket run ends accept 1/2" PVC pipe for permanent solvent-cement bonds forming the continuous inline run, while the 1/2" FPT branch outlet accepts any standard 1/2" male NPT-threaded fitting, solenoid valve inlet, instrument connection, ball valve, sampling valve, chemical injection nipple, 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 1/2" socket distribution layout. This full-size configuration — where all three ports are 1/2" — is the standard entry in the confirmed 402 series 1/2" run sub-family and is distinct from the three other confirmed 402 series entries at the 1/2" run diameter: 402-071 (1/8" FPT branch, micro-bore bleed port only), 402-072 (1/4" FPT branch, standard instrument port for pressure gauges and transducers), and 402-074 (3/4" FPT bullhead branch, flow collection junction); 402-005 is the correct choice when the branch must accept any standard 1/2" male-threaded service, valve, or equipment component — the broadest and highest-demand branch application across the entire confirmed 1/2" run 402 sub-family. At 1/2", this tee appears throughout drip and micro-irrigation distribution assemblies where 1/2" socket supply runs must supply 1/2" male-threaded solenoid valve inlets, pressure regulators, and filter housing connections; in instrument manifold assemblies where a 1/2" socket supply run must provide a 1/2" female-threaded measurement or control branch; and in chemical injection and process piping assemblies where a 1/2" socket distribution run must serve a 1/2" male-threaded injection port, sampling valve, or service component in a compact single-fitting junction body. It should not be confused with the full-size all-slip 401-005 (if stocked), which provides a 1/2" socket branch outlet for a continuing cemented pipe run rather than a female-threaded branch for a male-threaded component.

Rated to approximately 600 psi at 73°F — the highest confirmed pressure rating in the 402 series at 1/2" — this tee is suited for standard commercial and light industrial pressure service. 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. On the 1/2" 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 — PVC female threads require hand-tight plus one to two turns. Allow adequate cure time on the cemented joints before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Drip & Micro-Irrigation Systems — Provides the standard mixed-connection branch junction at 1/2" solenoid valve inlet stubs, pressure regulator male-threaded connections, filter housing FPT inlets, and manifold component male-threaded ports throughout 1/2" all-socket drip and micro-irrigation distribution assemblies where the socket run must simultaneously continue inline and supply a 1/2" male-threaded downstream component at the branch location without a separate female adapter at the branch port
• Irrigation & Water Distribution — Distributes water from a 1/2" socket distribution run to a 1/2" male-threaded branch service valve, pressure gauge connection, zone control component, or equipment feed connection in residential and light commercial irrigation systems where the socket main run must continue inline while simultaneously providing a female-threaded branch receptacle for a 1/2" male-threaded service component at the tee junction
• Instrument & Process Piping — Provides a standard mixed-connection three-way junction on 1/2" socket instrument supply runs, chemical feed distribution lines, and small-bore service manifold assemblies in water treatment, chemical processing, and manufacturing facilities where a 1/2" male-threaded valve body, instrument connection, sampling valve, or equipment port must be served directly off a 1/2" socket pipe run at the inline branch tap point
• Chemical Handling — Provides a corrosion-resistant mixed-connection branch junction at 1/2" socket chemical feed lines, injection system supply runs, and dosing manifold lateral assemblies where a 1/2" male-threaded injection port, metering component inlet, or service valve must be tapped off the all-socket supply run without an intermediate female adapter at the branch location
• Water Treatment & Aquaculture — Used at inline branch tap points along 1/2" all-socket distribution runs where a 1/2" 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
• Commercial Plumbing — Provides mixed-connection branch junctions on 1/2" socket dedicated service supply runs, branch supply headers, and fixture supply distribution assemblies in commercial building water distribution systems where 1/2" male-threaded service valves, equipment connections, and instrument components must be served at inline branch tap points along the all-socket pipe run
