Bushing, Spigot x FPT PVC Schedule 40 2" x 1/4" (438-245)

This 2" x 1/4" Schedule 40 PVC Reducer Bushing (Spigot x FPT) provides a compact mixed-connection transition from a 2" socket fitting hub down to a 1/4" female NPT-threaded instrument port outlet, consolidating an extreme 8:1 diameter reduction and a socket-to-thread material transition into a single fitting body — serving the highly specialized application of incorporating a pressure monitoring tap, gauge connection, sampling port, or small-bore chemical injection stub directly at a 2" socket fitting hub without an intermediate adapter chain 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 1/4" male-threaded instrument, sensor, pressure gauge, or service component 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 1/4" FPT interior accepts any standard 1/4" male NPT-threaded instrument fitting, pressure gauge connection, sampling valve, chemical injection nipple, or sensor port for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The 1/4" FPT outlet is the industry-standard connection size for pressure gauges, pressure transducers, temperature sensors, sampling valves, and small-bore chemical injection ports throughout commercial and industrial PVC piping systems — making this bushing the correct single-fitting solution wherever a 2" socket assembly must incorporate an instrument or monitoring tap without the space, fitting count, and leak-point overhead of a separate tee, nipple, hex bushing, and adapter chain at the same port 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 1/4" if stocked), which would provide a 1/4" socket outlet for a cemented pipe run rather than a threaded instrument connection, or with the 438-248 (2" x 3/4" FPT, confirmed in this catalog session), which serves moderate-flow threaded zone valve and service component connections at a much larger outlet diameter.

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 1/4" FPT end, use PTFE tape — wrapping a minimum of two to three times in the thread direction — and confirm that the 1/4" male NPT threads of the mating instrument or service component are started by hand and seated squarely before applying final torque; at 1/4", the shallow thread engagement depth makes cross-threading a more common installation error than at larger diameters, and a cross-threaded joint at this small size can crack the female thread interior without being immediately apparent. Avoid over-torquing — PVC threads require hand-tight plus one to two turns; at 1/4" this means a particularly short engagement range before overtorque risk. 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:

• Industrial Process Piping — Incorporates 1/4" male-threaded pressure gauge taps, pressure transducer connections, temperature sensor ports, sampling valve stubs, and small-bore chemical injection fittings directly at 2" socket fitting hubs on process water distribution headers, chemical feed mains, and industrial fluid handling assemblies in water treatment, chemical processing, and manufacturing facilities where instrument monitoring taps must be integrated into large-diameter socket assemblies without multi-piece transition chains
• Irrigation & Water Distribution — Provides 1/4" male-threaded pressure monitoring taps, pressure gauge connections, and small-bore instrument stubs directly at 2" socket tee branches, cross ports, and manifold hubs in agricultural and municipal irrigation pump stations and large-diameter distribution assemblies where system pressure monitoring points must be incorporated at mainline socket fitting ports without intermediate adapter assemblies
• Chemical Handling — Delivers a corrosion-resistant mixed-connection socket-to-instrument-port transition at 2" socket fitting hub ports in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, where 1/4" male-threaded pressure monitoring instruments, sampling valves, chemical injection stubs, and sensor connections 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 1/4" male-threaded pressure monitoring instruments, chemical dosing ports, sampling valves, and treatment equipment sensor connections must be incorporated directly at large-diameter socket fitting locations with NSF/ANSI 61 compliance required throughout the assembly
• Commercial Plumbing — Provides a 1/4" male-threaded pressure gauge tap, test point connection, or instrument stub directly at 2" socket fitting hub ports in commercial building water distribution systems where system pressure monitoring or test point access must be incorporated at socket fitting locations without a separate threaded adapter assembly at the port
• HVAC & Mechanical Systems — Incorporates 1/4" male-threaded pressure sensor connections, gauge taps, and instrument ports directly at 2" socket fitting hubs on cooling tower supply headers, chilled water distribution assemblies, and chemically treated water system socket fitting manifolds within the Schedule 40 pressure class where instrument monitoring tap points must be built into large-diameter socket assemblies
