Elbow, 90 Degree, Slip x FPT PVC Schedule 40 3/4" (407-007)

This 3/4" 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 mixed-connection fitting body — accepting 3/4" PVC pipe at the slip socket inlet for a permanent solvent-cement bond and providing a 3/4" female NPT-threaded outlet for receiving any 3/4" male-threaded valve, solenoid valve body, equipment connection, or service component at the 90-degree outlet. Constructed in white Schedule 40 PVC, it eliminates the need for a full-size 3/4" all-socket elbow plus a separate female adapter at the same direction change point — consolidating both the 90-degree pipe run turn and the socket-to-female-thread termination into a single fitting body wherever an all-socket 3/4" pipe run must simultaneously change direction and terminate at a female-threaded receptacle.

The 3/4" slip socket inlet accepts 3/4" PVC pipe for a permanent solvent-cement bond, cementing the fitting to the upstream all-socket pipe run at the direction change point. The 3/4" FPT outlet accepts any standard 3/4" male NPT-threaded solenoid valve body, valve inlet, pump port, equipment male-threaded connection, or fitting for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape, directing the female-threaded receptacle 90 degrees from the inlet socket axis. This Slip x FPT configuration occupies a unique position in the 3/4" 90-degree elbow family — it is the correct choice when an all-socket pipe run must both change direction 90 degrees AND transition to a female-threaded outlet for a downstream male-threaded component at the same fitting location, distinguishing it from the full-size Slip x Slip elbow (406 series, all-socket, both ends cement to pipe runs without a threaded interface), the FPT x FPT elbow (408-007 confirmed, all-threaded, both ends accept male nipples without a cemented socket), the MPT x Slip elbow (410-007 confirmed, MPT inlet threads into a female port rather than cementing to a pipe run, slip outlet continues to a socket pipe run), and the Spigot x FPT elbow (411-007 confirmed, spigot cements into a fitting hub interior rather than accepting a pipe end in a socket). The two-function efficiency argument is particularly compelling at 3/4" in residential irrigation valve box and pump station assemblies — where a 3/4" socket supply pipe run approaching the valve box must simultaneously make a 90-degree turn at the box entry point and terminate at a female-threaded receptacle for the solenoid valve body's MPT inlet, and where the single 407-007 fitting replaces both a separate 3/4" Slip x Slip 90-degree elbow and a 3/4" Slip x FPT female adapter (435-007 confirmed in this session) that would otherwise be required in sequence to accomplish the same two-function transition.

Rated to approximately 480 psi at 73°F (governed by the 3/4" slip end), this elbow is suited for standard commercial and light industrial pressure service. Its dual ASTM construction — D2466 at the slip socket end and D2464 at the FPT end — confirms compliance across both connection methods in the mixed-connection configuration. 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. On the 3/4" 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 at the FPT outlet — PVC female threads require hand-tight plus one to two turns; excessive torque through the mating male component can crack the FPT outlet. Plan the FPT outlet direction before cementing the slip inlet joint — the female-threaded outlet orientation is established when the slip inlet is cemented and cannot be adjusted after cure. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Simultaneously changes direction 90 degrees and terminates a 3/4" all-socket pipe run at a female-threaded receptacle for solenoid valve body MPT inlets, valve station valve body connections, and zone manifold male-threaded entry ports in residential and light commercial irrigation valve box and pump station assemblies where the 3/4" socket supply pipe must both change direction and transition to a female-threaded termination at the same fitting location — eliminating a separate socket elbow plus female adapter at the valve box approach point
• Commercial Plumbing — Provides a compact 90-degree socket-to-FPT direction change at branch supply distribution corners, wall penetration approach points, and equipment connection turns in commercial building water distribution systems where a 3/4" socket pipe run must simultaneously change direction and terminate at a female-threaded outlet for a downstream male-threaded valve, equipment port, or service component
• Pump Station Assemblies — Provides a simultaneous 90-degree direction change and socket-to-female-thread termination at pump suction and discharge approach corners, valve station assembly entry points, and bypass line direction change locations in pump station installations where a 3/4" all-socket pipe run must redirect and terminate at a female-threaded receptacle for a pump body MPT connection, valve body inlet, or service component in a single compact fitting
• Industrial Process Piping — Transitions 3/4" socket process water distribution runs at 90-degree routing corners that must simultaneously terminate at female-threaded instrument connections, valve body inlets, equipment ports, and service component male-threaded interfaces in water treatment, chemical processing, and manufacturing facilities where a single fitting replaces a separate socket elbow plus female adapter at each direction-change-plus-termination point
• Water Treatment & Aquaculture — Used at 90-degree routing turns along 3/4" all-socket distribution runs where the pipe must simultaneously change direction and terminate at a female-threaded pump inlet, filter housing MPT connection, treatment equipment port, or instrument stub with NSF/ANSI 61 compliance required throughout the mixed-connection assembly
• Chemical Handling — Delivers a corrosion-resistant 90-degree socket-to-FPT direction change and termination at routing corners in 3/4" all-socket chemical distribution assemblies where the downstream component presents a 3/4" male NPT thread at a 90-degree turn point — maintaining all-socket upstream construction while providing a female-threaded receptacle at the direction change for male-threaded metering, injection, or service components incompatible with metal fittings
