Street Elbow, 90 Degree, Spigot x FPT PVC Schedule 40 1-1/2" (411-015)

This 1-1/2" Schedule 40 PVC 90 Degree Street Elbow (Spigot x FPT) provides a compact, mixed-connection right-angle turn that transitions directly from a socket-end fitting hub to a 1-1/2" female-threaded connection — combining the space-saving plug-in characteristic of a street elbow with a built-in threaded outlet in a single fitting body. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial applications where a 90-degree socket-to-thread transition must be made in the tightest possible assembly footprint without the pipe section or nipple that a standard elbow configuration would require between the upstream socket fitting and the downstream threaded component.

The 1-1/2" spigot (male plain end) is sized to insert directly into the hub of any standard 1-1/2" socket-end fitting — tee outlet, cross port, coupling end, elbow socket, or valve body — and is solvent-cemented in place to form a permanent, leak-free joint at the outer face of the upstream fitting. The 1-1/2" FPT interior accepts any standard 1-1/2" male NPT-threaded fitting, nipple, valve, pump port, or equipment connection for a pressure-tight mechanical joint when made up with thread sealant or PTFE tape. By plugging directly into the upstream socket fitting, the 411 street elbow eliminates the short pipe nipple or connecting pipe section that a standard Slip x Slip elbow would require — reducing the overall assembly length, lowering fitting count, and enabling direction changes in confined spaces where every inch of clearance matters. This Spigot x FPT mixed-connection geometry makes the 411 series the correct choice wherever a socket-based PVC assembly must turn 90 degrees and immediately transition to a threaded male component at the same location, without an intermediate slip socket, separate adapter, or pipe section between the turn and the threaded interface.

Rated to approximately 330 psi at 73°F (governed by the 1-1/2" spigot end), this elbow is suited for standard commercial and light industrial pressure service. 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.

Apply solvent cement to the spigot exterior and the interior of the receiving socket hub per ASTM D2564 procedures, inserting fully and holding briefly for initial set. Plan the direction of the FPT outlet before cementing — the spigot joint orientation establishes the outlet direction and cannot be adjusted after cure. On the 1-1/2" FPT end, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating component before engagement. Avoid over-torquing the threaded connection — PVC threads require hand-tight plus one to two turns. 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:

• Irrigation & Water Distribution — Plugs directly into 1-1/2" socket tee outlets, cross ports, and coupling ends at valve station assemblies and pump discharge connections in agricultural and municipal irrigation systems, providing an immediate 90-degree turn and threaded outlet at the socket fitting face without the connecting nipple a standard elbow would require
• Commercial Plumbing — Provides a compact 90-degree socket-to-thread transition at structural corners, wall penetrations, and equipment connection points in commercial building water distribution systems where assembly clearance is limited and eliminating the nipple between the upstream socket fitting and the downstream threaded component is a practical space-saving requirement
• Industrial Process Piping — Transitions 1-1/2" socket fitting hubs directly to 90-degree turns with threaded outlets at pump inlets, valve station connections, and equipment interfaces in water treatment, chemical processing, and manufacturing facilities where compact assembly footprint at mixed socket-and-threaded connection points is a design priority
• Chemical Handling — Provides a corrosion-resistant, compact socket-to-thread 90-degree turn in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, particularly in tight equipment enclosures and chemical distribution assemblies where minimizing the distance between the upstream socket fitting and the downstream threaded component is spatially critical
• Water Treatment & Aquaculture — Used at pump discharge socket fittings, filter housing socket ports, and recirculating system header connection points where a compact 90-degree socket-to-thread turn is required at the socket fitting face and NSF/ANSI 61 compliance is required throughout the assembly
• HVAC & Mechanical Systems — Plugs directly into socket fitting hubs on cooling tower supply headers, chilled water distribution assemblies, and chemically treated water systems to provide compact 90-degree socket-to-thread turns at valve connections, equipment interfaces, and panel penetrations within the Schedule 40 pressure class
