Street Elbow, 90 Degree, Spigot x FPT PVC Schedule 40 1-1/4" (411-012)

This 1-1/4" Schedule 40 PVC 90 Degree Street Elbow (Spigot x FPT) combines a compact socket-inlet right-angle turn with a female-threaded outlet in a single fitting body — cementing directly into an existing socket fitting hub on the inlet side and providing a 1-1/4" female NPT-threaded connection on the outlet side for a male-threaded component, nipple, or valve. Constructed in white Schedule 40 PVC, it eliminates both the intermediate pipe section required by a standard Slip x Slip 90-degree elbow and the separate socket-to-thread adapter that would otherwise be needed at the threaded outlet — producing the most compact possible right-angle socket-to-thread transition at any 1-1/4" socket fitting hub in an assembly.

The spigot (male plain end) inlet is sized to insert directly into the hub of any standard 1-1/4" socket-end fitting — tee branch outlet, cross port, coupling end, elbow outlet, or valve body — and is solvent-cemented in place to form a permanent, leak-free joint at the outer face of the hub. The 1-1/4" FPT outlet accepts any standard 1-1/4" male NPT-threaded fitting, nipple, valve, or equipment connection, providing a female-threaded termination perpendicular to the upstream socket fitting hub in a single compact body. This Spigot x FPT mixed-connection configuration is the correct choice when a right-angle direction change and a socket-to-threaded material transition must occur simultaneously at the same fitting hub location — as opposed to the 409 series (Spigot x Slip, all-socket), which provides a socket outlet for a continuing PVC pipe run rather than a threaded component, or the 412 series (MPT x FPT, all-threaded), which threads into a female port rather than cementing into a socket hub. The 411 series is most commonly encountered at tee branch outlets, cross ports, and socket valve body outlets where a compact right-angle turn must immediately transition to a male-threaded zone valve, solenoid inlet, pressure gauge connection, or equipment port — eliminating the chain of fittings that a separate spigot elbow plus female adapter or a socket elbow plus nipple plus adapter would otherwise require.

Rated to approximately 370 psi at 73°F (governed by the 1-1/4" spigot end), this elbow is suited for standard commercial and light industrial water distribution and irrigation service within its pressure class. Its dual ASTM construction — D2466 at the socket spigot end and D2464 at the FPT end — confirms compliance across both connection methods. 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. On the 1-1/4" FPT outlet, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating downstream component before engagement; avoid over-torquing — PVC threads require hand-tight plus one to two turns. Plan the FPT outlet direction before cementing the spigot into the upstream hub — both the spigot insertion orientation and the resulting FPT outlet direction are fixed permanently once the cement cures. Allow adequate cure time on the cemented joint before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Transitions 1-1/4" socket-end tee branches, cross ports, and manifold fitting hubs directly to 1-1/4" male-threaded zone control valves, solenoid valve inlets, and filter housing connections at a compact 90-degree right angle in agricultural and municipal irrigation systems where a simultaneous direction change and socket-to-thread transition at the fitting hub eliminates a separate adapter and reduces assembly footprint at valve station connection points
• Commercial Plumbing — Provides a compact right-angle socket-to-thread transition at socket fitting hubs, tee branch outlets, and valve body socket ports in commercial building water distribution systems where a male-threaded branch component must be connected at a 90-degree angle directly off a socket fitting port without an intermediate pipe section or separate thread adapter
• Industrial Process Piping — Transitions 1-1/4" socket fitting hub ports to male-threaded instrument connections, valve bodies, flow meters, and equipment inlets at a compact 90-degree angle in water treatment, chemical processing, and manufacturing facilities where the simultaneous direction change and socket-to-thread transition reduces fitting count at constrained connection points throughout the system
• Chemical Handling — Provides a corrosion-resistant compact 90-degree socket-to-thread transition at socket fitting hubs in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, where a male-threaded valve, metering component, or chemical injection port must be served at a right angle directly off a 1-1/4" socket fitting hub in a single fitting body
• Water Treatment & Aquaculture — Used at pump connection tee branch outlets, filter housing socket ports, and treatment equipment socket-end connections where a compact 90-degree turn simultaneously transitions from the socket assembly to a 1-1/4" male-threaded instrument, valve, or equipment component with NSF/ANSI 61 compliance required throughout
• HVAC & Mechanical Systems — Produces a compact 90-degree socket-to-thread transition directly off socket fitting hubs on cooling tower supply tee branches, chilled water distribution manifold ports, and chemically treated water system equipment connections within the Schedule 40 pressure class where a male-threaded service component must be served at a right angle off a socket fitting port
