Elbow, 90 Degree Street, MPT x FPT PVC Schedule 40 1/2" (412-005)

This 1/2" Schedule 40 PVC 90 Degree Street Elbow (MPT x FPT) provides a compact right-angle direction change in all-threaded PVC piping systems with one male-threaded inlet and one female-threaded outlet — allowing the elbow to thread directly into any standard female-threaded port, fitting body, valve, solenoid valve body, or equipment connection without requiring an intermediate nipple at the inlet end. Constructed in white Schedule 40 PVC, it offers the corrosion resistance and chemical compatibility required across a wide range of irrigation, commercial plumbing, instrument distribution, and light industrial fluid handling applications where threaded construction is specified or preferred throughout the system at the standard small-bore 1/2" service and instrument assembly diameter.

The 1/2" MPT inlet threads directly into any standard 1/2" FPT or FIP female-threaded fitting, valve body, tee branch outlet, cross port, solenoid valve body, manifold FPT connection, pump port, or equipment female-threaded port, while the 1/2" FPT outlet accepts any standard 1/2" male NPT-threaded pipe end, nipple, or fitting for the downstream direction change leg. This MPT x FPT configuration — commonly referred to in the field as a street elbow or street ell — eliminates the need for a short nipple at the inlet end of the elbow, producing a more compact assembly at female-threaded ports where space is limited or where a nipple-plus-elbow combination would extend the assembly beyond available clearances. At 1/2", this is the smallest confirmed entry in the 412 series and the highest-pressure rated — carrying approximately 600 psi at 73°F, reflecting the elevated pressure capacity of small-bore Schedule 40 PVC threaded fittings — appearing throughout instrument manifold assemblies, chemical injection line direction changes, solenoid valve body outlet turns, small pump station piping, and compact all-threaded 1/2" service line assemblies in residential irrigation, commercial plumbing, and light industrial systems where 1/2" is the standard small-bore all-threaded service and instrument distribution diameter. When compact solenoid valve body outlets, close-quarters instrument manifold connections, or tight panel clearances make nipple-plus-elbow assemblies impractical at female-threaded 1/2" ports, the 412-005 delivers the most compact all-threaded right-angle solution available in the Schedule 40 PVC catalog at this small-bore service diameter.

Rated to approximately 600 psi at 73°F, this elbow carries the highest confirmed pressure rating in the 412 series — suited for standard commercial and light industrial water distribution, irrigation, and instrument service applications well within its pressure class. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal street elbows in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

Install using a quality pipe thread sealant or PTFE tape on all male NPT threads — both the 1/2" MPT inlet and the male NPT threads of any downstream component engaging the FPT outlet — before engagement. Avoid over-torquing — PVC threads require hand-tight plus one to two turns; excessive force can crack the fitting body or distort thread engagement, and at 1/2", the compact fitting body is more susceptible to overtorque cracking than at larger sizes. Plan the outlet direction of the elbow before final make-up, as the downstream pipe run alignment is established when the MPT inlet threads are fully engaged. Derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Threads directly into female-threaded solenoid valve body outlets, manifold FPT connections, tee branch female-threaded outlets, and valve station assembly ports on 1/2" all-threaded PVC irrigation assemblies, producing a compact 90-degree direction change without an intermediate nipple at each solenoid body outlet, compact valve station turn, and drip manifold direction change point in residential and light commercial irrigation systems where 1/2" is the standard small-bore all-threaded service connection and valve outlet diameter
• Instrument & Process Piping — Provides a compact right-angle direction change at 1/2" female-threaded instrument manifold connections, sample system distribution ports, chemical injection line turns, and instrument supply assembly direction change points in manufacturing, water treatment, and laboratory facilities where close-quarters all-threaded 1/2" instrument and chemical feed assemblies require compact 90-degree turns at female-threaded port locations throughout the distribution layout
• Chemical Handling — Provides a corrosion-resistant compact direction change at female-threaded ports in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, in all-threaded chemical feed manifolds, metering pump distribution headers, and injection line assemblies at 1/2" line sizes where eliminating an intermediate nipple at each turn reduces joint count and leak risk in compact small-bore chemical distribution assemblies
• Commercial Plumbing — Provides a compact right-angle turn at female-threaded ports on valves, manifold bodies, and distribution fitting assemblies in commercial building water supply systems where space constraints at 1/2" threaded connection points favor a street elbow over a nipple-plus-FPT-elbow combination at compact branch supply turn locations
• Water Treatment & Aquaculture — Used at female-threaded filter housing ports, pump connection FPT outlets, chemical dosing manifold connections, and treatment equipment female-threaded ports where a compact 90-degree turn is required in all-threaded 1/2" PVC assemblies and NSF/ANSI 61 compliance is needed throughout the small-bore threaded distribution system
• HVAC & Mechanical Systems — Threads directly into female-threaded valve bodies, equipment connections, and service line assembly ports on cooling tower supply branch lines, chilled water distribution service connections, and chemically treated water system 1/2" service assemblies within the Schedule 40 pressure rating class where a compact street elbow produces a tighter, lower-profile direction change than a nipple-and-elbow combination at small-bore 1/2" threaded ports
