Reducer Bushing, Spigot x FPT PVC Schedule 40 2" x 1" (438-249)

This 2" x 1" Schedule 40 PVC Reducer Bushing (Spigot x FPT) provides a compact mixed-connection transition from a 2" socket fitting hub down to a 1" female NPT-threaded outlet, consolidating a meaningful 2:1 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" male-threaded zone valve, pump inlet, filter housing, flow meter, or equipment connection must be installed directly at a 2" socket assembly port location — the most widely specified full-service threaded connection size in these systems.

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" FPT interior accepts any standard 1" male NPT-threaded fitting, valve, nipple, pump port, flow meter, or equipment connection for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The 1" FPT outlet is among the most widely specified full-service threaded connection sizes in commercial plumbing, irrigation, and light industrial PVC systems — making 438-249 one of the highest-demand entries in the 2" inlet 438 sub-series and the correct single-fitting solution wherever a 2" socket assembly must supply a 1" male-threaded full-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, 437-249 if stocked), which provides a 1" socket outlet for continuing a cemented PVC pipe run rather than connecting a male-threaded service component, with the adjacent 438-248 (2" x 3/4" FPT, for smaller-bore zone valve and service line connections), or with the 438-247 (2" x 1/2" FPT, for solenoid valve inlets and small-bore service taps). The 2" to 1" combination is also the direct Schedule 40 parallel to the confirmed 438-289 (2-1/2" x 1" FPT) at the larger 2-1/2" inlet — both serve the same 1" threaded full-service outlet application but at different socket hub inlet diameters.

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" 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" male-threaded zone control valves, pump inlets, filter housing connections, and full-service lateral distribution branches 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 1" threaded full-service components at valve station and distribution manifold connection points without intermediate adapter assemblies
• Commercial Plumbing — Incorporates 1" male-threaded branch service connections, valve inlets, pressure-reducing valve connections, and full-flow equipment feed taps directly at 2" socket fitting hub ports in commercial building water distribution systems where a full-service 1" threaded component must be served off a large-diameter 2" socket assembly port without a multi-piece transition at the port location
• Industrial Process Piping — Transitions 2" socket fitting hub branch outlets and manifold ports to 1" male-threaded pump inlets, valve bodies, flow meters, and full-service equipment connections in water treatment, chemical processing, and manufacturing facilities where 1" threaded downstream service components must be tapped directly off large-diameter 2" socket assembly ports in a single compact fitting body
• 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" male-threaded full-service valve inlets, pump connections, and equipment ports must be tapped directly off 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" male-threaded pump inlets, filter housing connections, UV sterilizer inlets, and full-service treatment equipment ports must be incorporated directly at large-diameter socket fitting locations with NSF/ANSI 61 compliance required throughout the assembly
• HVAC & Mechanical Systems — Incorporates 1" male-threaded valve connections, pump inlets, and full-service equipment taps 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
