Elbow, 90 Degree, Slip x FPT PVC Schedule 40 1-1/2" (407-015)

This 1-1/2" 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 1-1/2" slip socket end accepts standard 1-1/2" PVC pipe for solvent cement joining on the inlet side, while the 1-1/2" FPT end receives any compatible 1-1/2" male-threaded fitting, nipple, valve body, or equipment connection 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 is the defining characteristic that places the 407-015 between two adjacent elbow series at the same 1-1/2" Schedule 40 size. The 406-series all-socket 90° elbow serves fully solvent-welded systems where both sides of the right-angle turn are cemented plain PVC pipe ends — correct wherever the run continues as cemented pipe after the directional change. The 408-series all-threaded FPT × FPT 90° elbow (previously written at 2") serves fully threaded assemblies where both sides receive male-threaded nipples or fittings. The 407-015 occupies the middle position: the slip socket inlet integrates seamlessly into the solvent-welded pipe system, and the FPT outlet provides a female-threaded connection point for the downstream threaded component — accomplishing both the direction change and the system transition from cemented to threaded in a single compact fitting.

This combined function eliminates a fitting that would otherwise be required to achieve the same result with a standard elbow. A 406-series all-socket 90° elbow followed by a female adapter at the elbow outlet achieves the same directional change and threaded transition — but requires two fittings, two joints, and additional axial length in the assembly at that position. The 407-015 accomplishes both functions in a single body with two joints, preserving the compactness of the assembly and reducing total fitting count at every position where a 90° turn and a socket-to-thread transition must occur together.

At 1-1/2", the Slip × FPT 90° elbow serves a pipe size that appears broadly across residential and commercial Schedule 40 systems — pool and spa recirculation, commercial and residential irrigation, commercial plumbing, pump station outlet piping, and light industrial process connections. At each of these 1-1/2" system positions where a cemented pipe run must simultaneously change direction at 90° and connect to a threaded component, the 407-015 is the most direct single-fitting solution. Pool and spa equipment pad assemblies are a particularly defining context: the 1-1/2" cemented PVC recirculation run must frequently turn at 90° while connecting to a threaded pump port, valve body, filter head inlet, or equipment nozzle — exactly the combined direction-change-and-thread-transition function that the 407-015 accomplishes in a single body.

The 407-015 is the Schedule 40 counterpart to the Schedule 80 807-series Slip × FPT 90° elbow (previously written at 807-005 at 1/2"). Where the 807-series serves the same mixed-connection 90° elbow requirement in dark gray Schedule 80 PVC at higher pressure ratings, the 407-015 delivers the same functional configuration in white Schedule 40 PVC — correct for Schedule 40 systems where the pressure rating of 280 psi at 73°F is sufficient for the application.

Manufactured in white Schedule 40 PVC, this elbow delivers reliable performance across residential, commercial, and light industrial 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 pool and spa, irrigation, commercial plumbing, water treatment, and light industrial applications at 1-1/2". 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:

• Pool, Spa & Aquaculture — The defining application for the 1-1/2" Schedule 40 Slip × FPT 90° elbow: turns a 1-1/2" solvent-cemented PVC recirculation pipe run at 90° while simultaneously connecting to a male-threaded pump discharge port, filter head inlet, valve body, heater connection, or equipment nozzle in residential and commercial pool, spa, and aquatic facility installations — eliminating the all-socket 90° elbow-plus-female-adapter assembly that the same connection would require in two separate fittings
• Commercial & Residential Irrigation — Provides a 90° directional change and socket-to-thread transition at 1-1/2" pipe positions in irrigation pump station outlet assemblies, filter station connection runs, and control valve approach piping where the solvent-welded 1-1/2" pipe run must simultaneously turn at right angles and connect to a male-threaded valve body, strainer inlet, or pump port at the direction change position
• Commercial Plumbing — Routes a 1-1/2" solvent-welded Schedule 40 PVC supply branch through a 90° turn while transitioning to a female-threaded outlet at backflow preventer connections, pressure reducing valve inlets, shutoff valve body connections, and equipment supply branch points in mechanical room and building utility systems where the cemented pipe run must change direction and interface with a threaded component at the same fitting position
• Pump Station & Equipment Outlet Routing — Turns a 1-1/2" solvent-cemented PVC pump discharge or suction run at 90° while connecting directly to a male-threaded valve, strainer body, or equipment port at residential and commercial pump station connection assemblies and mechanical equipment pad piping where the combined direction-change-and-thread-interface function of the mixed elbow reduces fitting count at equipment connection points
• Water & Wastewater Treatment — Routes 1-1/2" Schedule 40 PVC solvent-welded distribution and process lines through 90° turns while transitioning to female-threaded outlet connections at pump port branches, valve body connections, and equipment nozzle interfaces in light-duty municipal and industrial water treatment facilities where the mixed-connection elbow accomplishes both the direction change and thread transition at the same fitting body position
• Light Industrial Process Piping — Provides a 90° directional change and cemented-to-threaded transition at 1-1/2" pipe run positions in light industrial process distribution headers, chemical handling connections, and equipment supply assemblies where the solvent-welded pipe run must turn at 90° and connect to a male-threaded process valve, strainer, or equipment component at the direction change point
• HVAC & Mechanical Systems — Routes 1-1/2" Schedule 40 PVC cooling tower makeup lines, treated water distribution branches, and equipment supply runs through 90° turns while connecting to male-threaded valve bodies, equipment nozzles, and connection nipples at panel entries, equipment connections, and structural clearance transitions in commercial mechanical system piping where the combined direction-change-and-thread-interface function reduces fitting count at threaded equipment connection turns
