Reducer Bushing, Spigot x FPT PVC Schedule 40 2" x 1/2" (438-247)

This 2" x 1/2" Schedule 40 PVC Reducer Bushing (Spigot x FPT) provides a compact mixed-connection transition from a 2" socket fitting hub down to a 1/2" female NPT-threaded outlet, consolidating a significant 4:1 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 1/2" male-threaded service component, solenoid valve inlet, chemical injection port, drip emitter manifold stub, or dedicated small-bore service fitting must be installed directly at a 2" socket assembly 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 1/2" FPT interior accepts any standard 1/2" male NPT-threaded fitting, solenoid valve inlet, chemical injection nipple, instrument connection, or service component for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The 1/2" FPT outlet is the most widely specified small-bore service connection size in residential and light commercial PVC irrigation and plumbing systems — making this bushing the likely highest-demand entry in the 2" inlet 438 sub-series and the correct single-fitting solution wherever a 2" socket assembly must supply a 1/2" male-threaded service component at a tee branch, cross port, or manifold hub without a separate reducer coupling plus threaded adapter at the same location. This Spigot x FPT configuration should not be confused with any 437 series all-slip counterpart at this size (Spigot x Slip, 2" x 1/2" if stocked), which provides a 1/2" socket outlet for continuing a cemented PVC pipe run rather than connecting a male-threaded service component, with the 438-245 (2" x 1/4" FPT, for extreme-reduction instrument port applications), or with the 438-248 (2" x 3/4" FPT, for larger-bore zone valve and service component connections).

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. 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 1/2" 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 — 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 — Provides 1/2" male-threaded solenoid valve inlets, drip emitter manifold stubs, small-bore service line taps, and dedicated branch connections directly at 2" socket tee branches, cross ports, and manifold hubs in agricultural and municipal irrigation systems where the large-diameter 2" socket mainline assembly must supply multiple 1/2" threaded service components at valve station and distribution manifold locations
• Commercial Plumbing — Incorporates 1/2" male-threaded branch service connections, pressure gauge taps, ball valve inlets, and instrument stubs directly at 2" socket fitting hub ports in commercial building water distribution systems where a small-bore 1/2" threaded service connection must be tapped off a large-diameter 2" socket assembly without an intermediate adapter chain at the port location
• Industrial Process Piping — Transitions 2" socket fitting hub branch outlets and manifold ports to 1/2" male-threaded instrument connections, chemical injection ports, sampling valves, and small-bore service branch components in water treatment, chemical processing, and manufacturing facilities where 1/2" threaded downstream service components must be tapped directly off large-diameter 2" socket assembly ports
• 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, where 1/2" male-threaded chemical injection stubs, metering component inlets, and small-bore service line taps must be incorporated at large-diameter socket assembly ports without metal adapter chains
• Water Treatment & Aquaculture — Used at 2" socket tee branches, cross ports, and manifold hub outlets where 1/2" male-threaded chemical dosing ports, instrument connections, treatment equipment inlets, and small-bore service stubs must be incorporated directly at large-diameter socket fitting locations with NSF/ANSI 61 compliance required throughout
• HVAC & Mechanical Systems — Incorporates 1/2" male-threaded sensor connections, drain valve stubs, chemical feed taps, and small-bore service ports directly at 2" socket fitting hubs on cooling tower supply headers, chilled water distribution manifolds, and chemically treated water system socket assemblies within the Schedule 40 pressure class
