Reducing Tee, Slip x Slip x FPT PVC Schedule 40 1/2" x 1/2" x 3/4" (402-074)

This 1/2" x 1/2" x 3/4" Schedule 40 PVC Tee (Slip x Slip x FPT) provides a three-way mixed-connection junction in which the two inline run ends accept 1/2" PVC pipe via solvent-cement socket bonds while the perpendicular branch outlet provides a built-in 3/4" female-threaded connection that is intentionally larger than both run ends — a bullhead-style mixed-connection configuration that collects combined flow from two smaller 1/2" socket runs into a single larger 3/4" female-threaded outlet, or distributes from a 3/4" threaded supply into two smaller 1/2" socket downstream runs. Constructed in white Schedule 40 PVC, it combines the function of a collection manifold junction and a socket-to-thread transition in a single compact fitting body.

The two 1/2" slip socket run ends accept 1/2" PVC pipe for permanent solvent-cement bonds forming the inline portion of the tee, while the 3/4" FPT branch outlet accepts any standard 3/4" male NPT-threaded fitting, valve, nipple, pump port, filter housing, solenoid valve inlet, or equipment connection for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The enlarged 3/4" FPT branch relative to the 1/2" run ends accommodates the combined flow volume from both run legs — the defining characteristic of a bullhead configuration — while the female-threaded branch outlet provides direct compatibility with a 3/4" male-threaded downstream component without a separate adapter at the branch. This Slip x Slip x FPT bullhead configuration is most commonly encountered in small-bore collection manifolds and flow consolidation assemblies where two dedicated 1/2" socket supply or return lines must feed into a single 3/4" female-threaded pump inlet, filter housing, zone valve body, or manifold port; in drip irrigation zone consolidation headers where two 1/2" lateral supply runs collect into a 3/4" threaded zone valve or filter connection; and in instrument and chemical dosing distribution assemblies where combined 1/2" branch flows must be received by a 3/4" threaded component at the collection point. It should not be confused with any all-slip 401 series bullhead counterpart at this size (if stocked), which would provide a 3/4" socket branch rather than a 3/4" female-threaded branch for connecting to a male-threaded downstream component.

Rated to approximately 480 psi at 73°F (governed by the 3/4" FPT branch end), 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 — PVC 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:

• Drip & Micro-Irrigation Systems — Collects flow from two 1/2" socket lateral supply runs into a 3/4" female-threaded zone valve inlet, filter housing connection, or pressure regulator port at zone consolidation manifold points in drip and micro-irrigation systems where two small-bore socket supply branches must combine at a 3/4" threaded component connection — eliminating a separate all-slip bullhead tee plus female adapter at the same consolidation point
• Irrigation & Water Distribution — Consolidates two 1/2" socket supply or return lines into a 3/4" female-threaded pump suction inlet, filter housing port, or manifold connection in small-bore agricultural and residential irrigation systems where a compact single-fitting mixed-connection collection junction reduces fitting count and assembly footprint at the flow consolidation point
• Chemical Handling — Provides a corrosion-resistant mixed-connection collection junction in chemical dosing, metering, and injection distribution assemblies where two 1/2" socket chemical feed lines must consolidate into a 3/4" female-threaded metering pump inlet, dosing manifold port, or injection valve connection without a multi-piece adapter assembly at the collection point
• Industrial Process Piping — Collects flow from two 1/2" socket process water, sample, or instrument supply lines into a 3/4" female-threaded pump inlet, filter port, or equipment connection in water treatment, manufacturing, and laboratory installations where a compact single-fitting mixed-connection consolidation junction minimizes fitting count at small-bore collection points
• Water Treatment & Aquaculture — Used at small-bore collection manifold points, filter inlet consolidation branches, and recirculating system return assemblies where two 1/2" socket supply runs must combine into a 3/4" female-threaded component connection with NSF/ANSI 61 compliance required throughout the mixed-connection assembly
• Commercial Plumbing — Consolidates two 1/2" socket dedicated service supply lines into a 3/4" female-threaded valve body, filter housing, or equipment connection at branch consolidation points in commercial building water systems where a single compact fitting replaces a bullhead tee plus separate female adapter at the collection junction
