Elbow, 90 Degree, FPT x FPT PVC Schedule 40 3/4" (408-007)

This 3/4" 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 3/4" FPT (Female Pipe Thread) geometry per NPT tapered thread standards, each accepting any standard 3/4" 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, solenoid valve body outlets, and close-quarters valve station assemblies — wherever a right-angle turn is required in a system built entirely from threaded PVC components. 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 412-007 (MPT x FPT Street Elbow, confirmed in the immediately preceding session entry), which has a male-threaded inlet that threads directly into a female port and eliminates the nipple on one side. At 3/4", this elbow is the co-dominant highest-demand size in the 408 series alongside 408-010 (1") — appearing throughout residential and light commercial all-threaded PVC irrigation valve station assemblies, zone header distribution runs, small pump station piping, commercial plumbing branch supply connections, and chemical feed distribution lines where 3/4" is the most widely specified small-bore all-threaded PVC system diameter.

Rated to approximately 480 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, zone header runs, solenoid valve outlet connections, filter housing interfaces, and mainline direction change points in residential and light commercial irrigation systems where 3/4" all-threaded PVC construction is the standard valve station and lateral distribution assembly diameter and right-angle turns at male-threaded component interfaces are required throughout the system
• Commercial Plumbing — Redirects 3/4" 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, chemical feed lines, instrument manifold runs, and equipment feed connections in manufacturing and water treatment facilities where 3/4" all-threaded Schedule 40 PVC is used throughout the system at small-bore service distribution line 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 3/4" line sizes — the most common small-bore diameter in chemical feed and instrument manifold threaded assemblies
• Water Treatment & Aquaculture — Used at pump discharge turns, filter housing connection offsets, chemical dosing distribution direction changes, and recirculating system header turns in threaded PVC assemblies where NSF/ANSI 61 compliance and chemical resistance are required at 3/4" threaded joints throughout the all-threaded system
• HVAC & Mechanical Systems — Redirects 3/4" 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
