Elbow, 90 Degree, Slip x FPT PVC Schedule 40 1-1/4" (407-012)

This 1-1/4" Schedule 40 PVC Slip × FPT 90 Degree Elbow provides a right-angle directional change that simultaneously transitions from a solvent-cemented PVC pipe inlet to a female NPT threaded outlet in a single mixed-connection fitting. The 1-1/4" slip socket end accepts standard 1-1/4" PVC pipe for solvent cement joining on the inlet side, while the 1-1/4" FPT end receives any compatible 1-1/4" male-threaded fitting, nipple, valve body, pump port adapter, strainer connection, or equipment component on the outlet side at the 90° turn. The result is a single fitting that accomplishes both the right-angle routing change and the solvent-cement-to-thread interface transition at the same fitting body position.

The mixed Slip × FPT construction places the 407-012 precisely between the all-socket and all-threaded 90° elbow options at 1-1/4" Schedule 40. The 406-series all-socket elbow serves fully solvent-welded systems where both sides of the right-angle turn are cemented pipe ends — the correct selection wherever the run continues as cemented PVC pipe after the directional change. The 408-series all-threaded FPT × FPT elbow serves fully threaded assemblies where both sides receive male-threaded nipples or MPT fittings. The 407-012 occupies the middle position: the slip socket inlet integrates the fitting into the solvent-welded pipe system, and the FPT outlet provides a female-threaded connection for the downstream threaded component — accomplishing both the direction change and the system transition from cemented to threaded in a single compact body.

At 1-1/4", this mixed-connection 90° elbow serves the transitional pipe size profile that has been established throughout this catalog. The 1-1/4" pipe size bridges the hydraulic gap between 1" and 1-1/2" in Schedule 40 distribution hierarchies — appearing at pump suction and discharge approach connections, secondary distribution headers, strainer body inlet piping, filter vessel approach runs, and equipment supply connections where the 1-1/4" flow capacity specifically meets the design requirement. At each of these positions where a 1-1/4" cemented pipe run must simultaneously change direction at 90° and connect to a male-threaded component — a pump port adapter, strainer body inlet, valve body, equipment nozzle — the 407-012 is the direct single-fitting solution.

The 407-012 is the Schedule 40 counterpart to the mixed-connection 90° elbow at 1-1/4" in the broader elbow family. At 1-1/4", this combined direction-change-and-thread-transition function appears most commonly at pump station approach piping where the 1-1/4" cemented approach run must turn at 90° to meet a pump suction port, at strainer body connections where the approach run changes direction to enter the strainer inlet, at secondary header valve connections where a 1-1/4" cemented run must turn and connect to a valve body, and at compact equipment pad assemblies where fitting count minimization is a design objective.

The 407-012 differs from the 407-015 (1-1/2" Slip × FPT 90° elbow, previously written) solely in pipe size and the application context that size implies. The 407-015 serves the broader 1-1/2" residential and commercial context — pool and spa recirculation, residential irrigation submains, commercial plumbing secondary headers. The 407-012 serves the more narrowly defined 1-1/4" transitional size context — pump approach piping, strainer connections, secondary header equipment interfaces, and transitional-size valve connections in commercial and light industrial systems. Both accomplish the same combined direction-change-and-socket-to-thread function; the upstream pipe size and the system tier where each fitting appears are the differentiators.

The combined function of the 407-012 eliminates a fitting that would otherwise be required at this position. A 406-series all-socket 90° elbow plus a 1-1/4" female adapter at the elbow outlet achieves the same directional change and threaded transition in two fittings; the 407-012 accomplishes both in a single body, reducing joint count and assembly footprint at every 1-1/4" system position where a 90° turn and a socket-to-thread transition must occur together.

Manufactured in white Schedule 40 PVC, this elbow delivers reliable performance across commercial, light industrial, and residential piping applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life where metal elbows would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F, this fitting handles standard pressure service across irrigation, pool and spa, commercial plumbing, water treatment, and light industrial applications at 1-1/4". For the slip socket end, clean and dry the pipe end and socket interior before application. Apply purple PVC primer to both mating surfaces, then apply a uniform coat of Schedule 40 PVC solvent cement to both the pipe end and socket interior before inserting. Hold with a slight quarter-turn twist for 30 seconds and allow full cure time per the cement manufacturer's guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to all male threads engaging the FPT end before installing downstream components. Hand-tighten plus one to two turns — do not over-torque PVC female threads. Confirm the 90° turn orientation and the FPT outlet rotational alignment before cementing the slip socket end — the outlet thread orientation is set permanently at the slip socket joint and cannot be adjusted after curing. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Pump Suction & Discharge Approach Piping — Turns a 1-1/4" solvent-cemented Schedule 40 PVC pump approach run at 90° while simultaneously connecting to a 1-1/4" MPT pump port adapter, suction fitting, or discharge connection in residential and commercial pump station assemblies, irrigation pump stations, and pool and spa pump connection piping — the defining application for the 1-1/4" Slip × FPT 90° elbow given the frequency of 1-1/4" pump approach connections requiring simultaneous right-angle direction change and socket-to-thread transition
