Tee, Slip x Slip x FPT PVC Schedule 40 1-1/2" (402-015)

This 1-1/2" Schedule 40 PVC Tee (Slip x Slip x FPT) provides a full-size three-way junction in which the two inline run ends accept PVC pipe via solvent-cement socket bonds while the perpendicular branch outlet provides a built-in 1-1/2" female-threaded connection — combining a standard socket tee and a full-size threaded branch adapter into a single compact fitting body. Constructed in white Schedule 40 PVC, it eliminates the need for a separate all-slip tee plus a threaded bushing or adapter at the branch, reducing fitting count, shortening assembly time, and minimizing potential leak points wherever a full-size 1-1/2" threaded branch must be tapped off a socket PVC pipe run.

The two 1-1/2" slip socket run ends accept 1-1/2" PVC pipe for permanent solvent-cement bonds, maintaining full mainline diameter through the inline run. The 1-1/2" FPT branch outlet accepts any standard 1-1/2" male NPT-threaded fitting, valve, nipple, pump port, or equipment connection directly — without the intermediate step of cementing a separate tee, waiting for cure, and then threading in an adapter before the threaded component can be installed. Unlike the reducing variants in the 402 series (402-209 through 402-211), which step the branch outlet down to a smaller diameter, the 402-015 maintains full 1-1/2" diameter at all three ports — making it the correct choice when the downstream threaded component requires the full mainline diameter at the branch connection rather than a reduced bore. This configuration is most commonly encountered where a 1-1/2" socket distribution main must supply a full-size 1-1/2" threaded valve, pump inlet, union connection, or equipment port directly off the run without any diameter reduction at the branch tap point.

Rated to 330 psi at 73°F (governed by the 1-1/2" slip run ends), this tee is suited for standard commercial and light industrial water distribution and irrigation service within its pressure class. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal fittings in moisture-prone or chemically active environments. 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 across the joint surface. On the 1-1/2" 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 the threaded branch connection — PVC threads require hand-tight plus one to two turns. Allow adequate cure time on both cemented joints before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Taps full-size 1-1/2" male-threaded control valves, pump inlets, filter housing connections, and zone header branches directly off 1-1/2" socket PVC mains in agricultural and municipal irrigation systems where the downstream threaded component requires the full mainline diameter at the branch connection point
• Commercial Plumbing — Provides a built-in full-size 1-1/2" threaded branch outlet off socket PVC supply runs for ball valves, gate valves, pressure-reducing valves, and full-flow service branch connections in commercial building water distribution systems where no diameter reduction is required or desired at the branch tap location
• Industrial Process Piping — Taps full-size 1-1/2" male-threaded pump inlets, valve bodies, flow meters, and equipment connections directly off socket process water distribution headers in water treatment, chemical processing, and manufacturing facilities where maintaining full branch flow capacity at the tee location is a hydraulic design requirement
• Chemical Handling — Provides a corrosion-resistant mixed-connection full-size branch tap in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, at full-flow valve stations, pump connections, and chemical distribution branch points where a 1-1/2" male-threaded component must be served at full mainline capacity from a socket PVC run
• Water Treatment & Aquaculture — Used at pump inlet connections, full-size filter housing taps, UV sterilizer inlet branches, and recirculating system branch points where a 1-1/2" socket main must supply a full-size 1-1/2" threaded equipment or valve connection and NSF/ANSI 61 compliance is required throughout the assembly
• HVAC & Mechanical Systems — Branches full-size 1-1/2" male-threaded valve connections, pump inlet stubs, and full-flow service taps directly off socket PVC runs on cooling tower supply headers, chilled water distribution mains, and chemically treated water systems within the Schedule 40 pressure class
