Reducer Bushing, Spigot x FPT PVC Schedule 40 2" x 1-1/4" (438-250)

This 2" x 1-1/4" Schedule 40 PVC Reducer Bushing (Spigot x FPT) provides a compact mixed-connection near-full-size transition from a 2" socket fitting hub down to a 1-1/4" female NPT-threaded outlet, consolidating a 1.6:1 diameter reduction and a socket-to-thread material transition into a single fitting body — the most modest confirmed reduction in the 2" inlet 438 sub-series and primarily driven by the need to match a 1-1/4" threaded downstream component rather than by any significant hydraulic flow management requirement. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial installations where a 1-1/4" male-threaded valve, pump port, filter housing, or equipment connection must be installed directly at a 2" socket assembly port location without a separate hex bushing, inline reducer coupling, or multi-piece transition assembly.

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 1-1/4" FPT interior accepts any standard 1-1/4" male NPT-threaded fitting, valve, nipple, pump port, 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 is a 1-1/4" male-threaded fitting or device — distinct from the 439-250 (2" x 1-1/4" MPT x FPT Hex Bushing, confirmed in this catalog session), which threads into a 2" female-threaded port rather than cementing into a 2" socket hub, and from any 437 series all-slip counterpart (Spigot x Slip, 2" x 1-1/4" if stocked), which provides a 1-1/4" socket outlet for a cemented pipe run rather than a threaded component connection. The 1-1/4" FPT outlet is a widely specified intermediate threaded connection size in commercial plumbing, irrigation, and light industrial systems — most commonly encountered where 1-1/4" threaded zone valves, pump inlets, filter housing connections, or moderate-flow equipment ports must be served directly off a 2" socket mainline assembly at tee branches, cross ports, and manifold hub locations.

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 1-1/4" 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 — 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 1-1/4" male-threaded zone valve inlets, pump connection ports, filter housing connections, and moderate-to-high-flow service taps directly at 2" socket tee branches, cross ports, and manifold hubs in agricultural and municipal irrigation systems where 1-1/4" threaded downstream components must interface with a large-diameter 2" socket mainline assembly at valve station and distribution manifold locations without a separate hex bushing or adapter assembly
• Commercial Plumbing — Incorporates 1-1/4" male-threaded branch service connections, valve inlets, backflow preventer ports, and equipment feed connections directly at 2" socket fitting hub outlets in commercial building water distribution systems where near-full-size 1-1/4" threaded service components must be served off a large-diameter 2" socket assembly without an intermediate threaded transition fitting at the port location
• Industrial Process Piping — Transitions 2" socket fitting hub branch outlets and manifold ports to 1-1/4" male-threaded pump inlets, valve bodies, flow meters, and moderate-bore equipment connections in water treatment, chemical processing, and manufacturing facilities where a near-full-size all-socket-to-threaded transition at 2" socket ports serves 1-1/4" threaded downstream service components throughout the distribution assembly
• Chemical Handling — Delivers a corrosion-resistant near-full-size 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 1-1/4" male-threaded valve bodies, metering pump inlets, and moderate-bore chemical feed components must be connected directly at large-diameter socket assembly ports
• Water Treatment & Aquaculture — Used at 2" socket tee branches, cross ports, and manifold hub outlets where 1-1/4" male-threaded pump inlets, filter housing connections, and moderate-bore treatment equipment ports must be incorporated directly at large-diameter socket fitting locations with NSF/ANSI 61 compliance required throughout
• HVAC & Mechanical Systems — Transitions 2" socket fitting hub ports to 1-1/4" male-threaded pump connections, valve inlets, and moderate-flow service components on cooling tower supply headers, chilled water distribution manifolds, and chemically treated water system socket assemblies within the Schedule 40 pressure class where near-full-size socket-to-thread transitions at 2" ports serve 1-1/4" threaded downstream components
