90 Degree Elbow, FPT x FPT PVC Schedule 40 1-1/4" (408-012)

This 1-1/4" 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 commercial plumbing, irrigation, and light industrial fluid handling applications where threaded construction is specified or preferred throughout the system.

Both the inlet and outlet are cut to 1-1/4" FPT (Female Pipe Thread) geometry per NPT tapered thread standards, each accepting any standard 1-1/4" 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, equipment connections, structural obstructions, and close-quarters valve assemblies — wherever a right-angle turn is required in a system built entirely from threaded PVC components. At 1-1/4", this elbow is commonly specified in threaded PVC irrigation mainline assemblies, pump station piping, commercial plumbing branch supply connections, and light industrial process water systems where this intermediate diameter handles moderate-to-higher flow volumes at direction change points in all-threaded distribution runs.

Rated to approximately 370 psi at 73°F, this elbow is suited for standard commercial and light industrial water distribution and irrigation service 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, including use in drinking water distribution and treatment systems.

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 or distort thread engagement at the elbow body. 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:

• Irrigation & Water Distribution — Changes direction at threaded valve station assemblies, pump discharge connections, filter housing interfaces, and mainline direction change points in agricultural and municipal irrigation systems where 1-1/4" all-threaded PVC construction is used for moderate-to-higher-flow supply runs requiring a right-angle turn at threaded component interfaces
• Commercial Plumbing — Redirects 1-1/4" male-threaded pipe runs at wall penetrations, structural obstructions, and equipment connection points in commercial building water distribution systems where all-threaded PVC construction is specified or preferred and solvent-cement joints are absent at the direction change location
• Industrial Process Piping — Provides a right-angle direction change in light-duty process water distribution assemblies, equipment feed lines, and cooling water runs in manufacturing and water treatment facilities where 1-1/4" all-threaded Schedule 40 PVC is used throughout the system at intermediate-diameter direction change points
• Chemical Handling — Performs reliably at direction change points in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, providing a pressure-rated right-angle turn within all-threaded PVC chemical distribution and feed assemblies at 1-1/4" line sizes where the intermediate diameter serves moderate-flow distribution runs
• Water Treatment & Aquaculture — Used at pump discharge turns, filter housing connection offsets, and recirculating system header direction changes in threaded PVC assemblies where NSF/ANSI 61 compliance and chemical resistance are required at 1-1/4" threaded joints throughout the all-threaded system
• HVAC & Mechanical Systems — Redirects 1-1/4" male-threaded pipe runs at equipment connection points, panel penetrations, and distribution header turns on cooling tower supply assemblies, chilled water branch lines, and chemically treated water systems within the Schedule 40 pressure rating class
