Reducer Bushing, Spigot x FPT PVC Schedule 40 2" x 3/4" (438-248)

This 2" x 3/4" Schedule 40 PVC Reducer Bushing (Spigot x FPT) provides a compact mixed-connection transition from a 2" socket fitting hub down to a 3/4" female NPT-threaded outlet, consolidating a significant 2.67:1 diameter reduction and a socket-to-thread material transition into a single fitting body without the need for a separate inline reducer coupling, hex bushing, or multi-piece transition assembly. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial installations where a corrosion-resistant socket-to-threaded transition is required at an existing large-diameter fitting port and a 3/4" male-threaded component must be installed directly at that port location.

The 2" spigot (male plain end) is sized to insert directly into the hub of any standard 2" socket-end fitting — tee branch outlet, cross port, coupling end, elbow outlet, or valve body — and is solvent-cemented in place to form a permanent, leak-free joint at the outer face of the hub. The 3/4" FPT interior accepts any standard 3/4" male NPT-threaded fitting, valve, nipple, solenoid inlet, zone valve, pressure gauge, or equipment connection for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. This Spigot x FPT mixed-connection configuration is the correct choice when the upstream 2" assembly is an all-socket PVC system and the downstream component at the branch or port location is a 3/4" male-threaded fitting or device — eliminating both the intermediate pipe section required by a separate tee-plus-spigot-elbow approach and the all-threaded hex bushing approach that would require a threaded female port at the inlet. It should not be confused with any 437 series all-slip counterpart at this size (Spigot x Slip, 2" x 3/4" if stocked), which provides a 3/4" socket outlet for continuing a PVC socket pipe run rather than connecting a male-threaded component, or with MPT x FPT hex bushings, which install entirely within threaded assemblies. At 2", the 3/4" FPT outlet is most commonly encountered on tee branch outlets, cross ports, and manifold socket connections where 3/4" threaded zone valves, solenoid valve inlets, pressure monitoring connections, and chemical injection ports must be served directly off a large-diameter 2" socket mainline assembly without a separate threading adapter.

Rated to approximately 280 psi at 73°F (governed by the 2" spigot end), this bushing is suited for standard commercial and light industrial water distribution and irrigation service within its pressure class. Its dual ASTM construction — D2466 at the spigot end and D2464 at the FPT end — confirms compliance across both connection methods. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to the spigot exterior and the interior of the receiving 2" socket hub per ASTM D2564 procedures, inserting fully and holding briefly for initial set. On the 3/4" FPT end, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating downstream component before engagement. Avoid over-torquing the threaded connection — PVC threads require hand-tight plus one to two turns. Allow adequate cure time on the cemented spigot joint before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Taps 3/4" male-threaded zone control valves, solenoid valve inlets, filter housing connections, and pressure gauge ports directly off 2" socket-end mainline tees and crosses in agricultural and municipal irrigation systems where the large-diameter 2" socket assembly must supply a 3/4" threaded branch component at valve station and distribution manifold connection points without an intermediate adapter or threaded nipple
• Commercial Plumbing — Provides a compact socket-to-thread transition at 2" socket fitting hub branch outlets, manifold ports, and tee connections in commercial building water distribution systems where a 3/4" male-threaded valve, pressure gauge, backflow preventer connection, or dedicated service component must be served directly off a 2" socket assembly port
• Industrial Process Piping — Transitions 2" socket fitting hub branch outlets and manifold ports to 3/4" male-threaded instrument connections, sampling valves, chemical injection ports, and service branch components in water treatment, chemical processing, and manufacturing facilities where the all-socket 2" mainline assembly must interface with 3/4" threaded downstream service components at multiple tap points
• Chemical Handling — Delivers a corrosion-resistant mixed-connection socket-to-thread transition at 2" socket fitting hub ports in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, particularly where 3/4" male-threaded metering components, injection ports, and chemical feed valves must be tapped directly off a large-diameter 2" socket distribution assembly
• Water Treatment & Aquaculture — Used at 2" socket tee branches, cross ports, and manifold hub outlets where a 3/4" male-threaded instrument connection, dosing port, or treatment equipment inlet must be served directly off a large-diameter socket fitting with NSF/ANSI 61 compliance required throughout the assembly
• HVAC & Mechanical Systems — Transitions 2" socket fitting hub branch outlets to 3/4" male-threaded sensor connections, drain valve stubs, chemical feed taps, and service components on cooling tower supply headers, chilled water distribution manifolds, and chemically treated water system socket assemblies within the Schedule 40 pressure class
