Elbow, 90 Degree, Slip x FPT PVC Schedule 40 1/2" (407-005)

This 1/2" Schedule 40 PVC 90 Degree Elbow (Slip x FPT) combines a right-angle direction change and a socket-to-female-thread material transition into a single compact fitting body — accepting a 1/2" PVC pipe at the slip socket inlet for a permanent solvent-cement bond and providing a 1/2" female NPT-threaded outlet at 90 degrees for receiving any standard 1/2" male-threaded valve, instrument connection, equipment port, or service component. Constructed in white Schedule 40 PVC, it eliminates both the separate all-socket 90-degree elbow and the separate socket-to-FPT female adapter that would otherwise be required in sequence at the same assembly location — producing the most compact possible right-angle socket-to-female-thread transition at any 1/2" all-socket pipe run turn-and-terminate point.

The 1/2" slip socket inlet accepts 1/2" PVC pipe for a permanent solvent-cement bond, anchoring the fitting to the upstream socket distribution assembly at the direction change and thread-transition point. The 1/2" FPT outlet accepts any standard 1/2" male NPT-threaded fitting, solenoid valve inlet, instrument connection, pressure gauge, sampling valve, chemical injection nipple, or equipment port for a pressure-tight mechanical connection at 90 degrees from the upstream pipe run axis when made up with thread sealant or PTFE tape. This Slip x FPT configuration is the correct choice when three conditions must be met simultaneously at the same assembly point: a 1/2" socket pipe run upstream, a 90-degree direction change required at the pipe run termination, and a 1/2" female-threaded receptacle required at that turn for a male-threaded downstream component. It should not be confused with the 411 series (Spigot x FPT), which cements into a 1/2" socket fitting hub interior rather than accepting a 1/2" pipe end in a socket — both share an FPT outlet but differ fundamentally in inlet geometry; nor with the 410-005 (MPT x Slip, confirmed in this session), which is the functional inverse — threading into a female port at the inlet and providing a socket outlet rather than vice versa; nor with the 406 series (Slip x Slip, all-socket), which provides a socket outlet for a continuing cemented pipe run rather than an FPT outlet for a male-threaded component; nor with the 408-005 (FPT x FPT, confirmed in this session), which has female threads on both ends requiring male nipples on both sides. At 1/2", the Slip x FPT 90-degree elbow most commonly appears in compact drip and micro-irrigation manifold assemblies where a 1/2" socket supply run must turn 90 degrees and terminate at a solenoid valve body MPT inlet, pressure regulator male-threaded connection, or filter housing MPT port without an intermediate female adapter; in instrument supply line assemblies where a 1/2" socket distribution run must simultaneously change direction and provide a female-threaded instrument connection receptacle; and in chemical injection line assemblies where a 1/2" socket feed line must turn and terminate at a male-threaded injection component or metering valve body at the same assembly point.

Rated to approximately 600 psi at 73°F (governed by the 1/2" slip end), this elbow carries the highest confirmed pressure rating in the 407 series — suited for standard commercial and light industrial water distribution, irrigation, and instrument service applications well within its pressure class. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to both the pipe end and fitting socket per ASTM D2564 procedures, inserting fully and maintaining a quarter-turn during assembly. Plan the FPT outlet direction before cementing the inlet joint — the downstream 90-degree outlet alignment is established when the slip joint is cemented and cannot be adjusted after cure. On the 1/2" FPT end, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating downstream component before engagement. Avoid over-torquing at the FPT end — PVC female threads require hand-tight plus one to two turns. Allow adequate cure time before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Drip & Micro-Irrigation Systems — Simultaneously changes direction and transitions from a 1/2" socket supply run to a female-threaded receptacle for solenoid valve body MPT inlets, pressure regulator male-threaded connections, and filter housing MPT ports in residential and light commercial drip and micro-irrigation manifold assemblies where both the 90-degree turn and the socket-to-FPT material transition must occur at the same compact fitting location without separate elbow and adapter fittings in sequence
• Irrigation & Water Distribution — Provides a compact right-angle socket-to-female-thread transition at solenoid valve body MPT inlets, backflow preventer connections, and irrigation component male-threaded ports in residential and light commercial irrigation systems where a 1/2" socket supply run must simultaneously turn 90 degrees and terminate at a female-threaded receptacle for a male-threaded irrigation component at the pipe run end
• Instrument & Process Piping — Transitions a 1/2" socket instrument supply run simultaneously 90 degrees and to a female-threaded instrument connection, sampling valve male-threaded inlet, or sensor port in manufacturing, water treatment, and laboratory facilities where the socket supply run must both change direction and transition to a female-threaded interface for a male-threaded instrument component at the same compact fitting location
• Chemical Handling — Provides a corrosion-resistant combined right-angle direction change and socket-to-FPT transition at 1/2" chemical feed pipe run termination and direction change points in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings where a male-threaded injection component, metering valve, or dosing system connection must be reached at a 90-degree turn from the all-socket supply run
• Water Treatment & Aquaculture — Used at 1/2" socket pipe run turn-and-terminate points where a male-threaded pump connection, filter housing port, chemical dosing component, or treatment equipment inlet must be reached at a 90-degree turn from the socket distribution run with NSF/ANSI 61 compliance required throughout the mixed-connection assembly
• Commercial Plumbing — Provides a compact right-angle socket-to-female-thread transition at 1/2" dedicated fixture supply and equipment feed pipe run corners in commercial building water distribution systems where the socket run must simultaneously turn 90 degrees and terminate at a female-threaded receptacle for a male-threaded service valve, equipment inlet, or branch component at the pipe run direction change point
