Elbow, 90 Degree, FPT x FPT PVC Schedule 40 1/2" (408-005)

This 1/2" Schedule 40 PVC 90 Degree Elbow (FPT x FPT) provides a right-angle direction change within all-threaded PVC piping systems, accepting male NPT-threaded pipe ends, nipples, or fitting outlets on both ports without introducing solvent-cement joints into the assembly. 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.

Both the inlet and outlet are cut to 1/2" FPT (Female Pipe Thread) geometry per NPT tapered thread standards, each accepting any standard 1/2" male NPT pipe end, nipple, or fitting for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The 90-degree turn allows all-threaded pipe runs to change direction cleanly at wall penetrations, compact assembly enclosures, solenoid valve outlet connections, instrument manifold direction change points, and chemical injection line routing turns — wherever a right-angle direction change is required in a 1/2" all-threaded PVC assembly without introducing socket joints into the run. This FPT x FPT configuration requires a male pipe end or nipple on both sides of the elbow, providing full flexibility in assembly orientation since neither end is fixed by a male thread engagement direction; it should not be confused with the 412-005 (MPT x FPT Street Elbow, confirmed in this catalog session), which has a male-threaded inlet that threads directly into a female port and eliminates the nipple on one side — the most critical disambiguation at this size given both are confirmed 1/2" all-threaded 90-degree elbows in this catalog session. At 1/2", this is the smallest confirmed entry in the 408 series and the highest-pressure rated — carrying approximately 600 psi at 73°F — 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.

Rated to approximately 600 psi at 73°F, this elbow carries the highest confirmed pressure rating in the 408 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 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 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 threads are fully engaged. Derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Instrument & Process Piping — Changes direction on 1/2" all-threaded instrument manifold runs, sample system distribution assemblies, chemical injection line routing, and instrument supply 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 male-threaded nipple connection points throughout the compact distribution layout
• Irrigation & Water Distribution — Changes direction at 1/2" all-threaded solenoid valve outlet assemblies, valve station compact runs, and small-bore service line direction change points in residential and light commercial irrigation systems where 1/2" all-threaded construction is specified for dedicated service connections and valve outlet assemblies requiring a right-angle turn at male-threaded nipple interfaces
• Chemical Handling — Provides a corrosion-resistant compact direction change at male-threaded nipple interfaces 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 right-angle turns are required at male-threaded assembly points throughout the small-bore distribution layout
• Commercial Plumbing — Redirects 1/2" male-threaded pipe runs at compact assembly enclosures, panel penetrations, and branch supply direction change points in commercial building water distribution systems where all-threaded PVC construction is specified or preferred and a right-angle turn is required at a male-threaded nipple interface without solvent-cement joints at the direction change location
• Water Treatment & Aquaculture — Used at 1/2" all-threaded instrument tap assemblies, chemical dosing distribution lines, and small-bore service manifold direction change points where NSF/ANSI 61 compliance and chemical resistance are required at 90-degree turns in all-threaded PVC assemblies throughout the treatment system
• HVAC & Mechanical Systems — Redirects 1/2" male-threaded pipe runs at equipment connection points, panel penetrations, and service line distribution header turns on cooling tower supply branch assemblies, chilled water distribution service connections, and chemically treated water system 1/2" service assemblies within the Schedule 40 pressure rating class
