Elbow, 90 Degree Reducing, Slip x FPT PVC Schedule 40 3/4" x 1/2" (407-101)

This 3/4" x 1/2" Schedule 40 PVC 90 Degree Elbow (Slip x FPT) combines three simultaneous functions in a single compact fitting body — a right-angle direction change, a socket-to-thread material transition, and a 3/4" to 1/2" size reduction — accepting 3/4" PVC pipe at the slip socket inlet for a permanent solvent-cement bond and providing a 1/2" female NPT-threaded outlet for a male-threaded downstream component departing at 90 degrees. Constructed in white Schedule 40 PVC, it eliminates the three separate fittings — a full-size 3/4" slip elbow, a separate 3/4" slip-to-thread adapter, and a separate 3/4" to 1/2" reducer — that would otherwise be required to achieve the same result at the same assembly location, consolidating the direction change, thread transition, and size reduction into the most compact possible all-in-one fitting body.

The 3/4" slip socket inlet accepts 3/4" PVC pipe for a permanent solvent-cement bond, anchoring the fitting to the upstream 3/4" socket distribution assembly at the direction change point. The 1/2" FPT outlet accepts any standard 1/2" male NPT-threaded fitting, solenoid valve inlet, instrument connection, chemical injection nipple, service component, or equipment port for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape — simultaneously stepping the assembly diameter down from 3/4" to 1/2" and transitioning from a cemented socket run to a female-threaded receptacle at a 90-degree turn. This Slip x FPT configuration is the correct choice when all three conditions must be met simultaneously at the same assembly point: a 3/4" socket pipe run upstream requiring a 90-degree turn, a socket-to-thread material transition required at that turn, and a 1/2" male-threaded downstream component at the outlet of that turn. It should not be confused with the 406-101 (3/4" x 1/2" Slip x Slip 90° Reducing Elbow, confirmed in this session), which provides a 1/2" slip socket outlet for a continuing all-socket 1/2" cemented pipe run rather than a 1/2" female-threaded outlet for a male-threaded component — both fittings combine the same 90-degree turn and 3/4" to 1/2" size reduction but differ in outlet type; the correct choice between them is determined entirely by whether the downstream 1/2" connection is a socket pipe continuation (406-101) or a male-threaded component (407-101). At the 3/4" slip x 1/2" FPT size, this elbow most commonly appears in residential and light commercial irrigation assemblies where a 3/4" socket distribution run must simultaneously turn 90 degrees and supply a 1/2" male-threaded solenoid valve inlet, pressure regulator, or drip manifold component at the turn; in compact instrument and chemical feed assemblies where a 3/4" socket supply run must turn and transition to a 1/2" male-threaded instrument or service component in a single fitting; and in commercial plumbing branch supply assemblies where a 3/4" socket main must simultaneously turn and supply a 1/2" male-threaded fixture or equipment connection.

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. 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 1/2" FPT outlet, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating downstream component before engagement. Plan the outlet direction of the elbow before cementing the inlet joint — the downstream 1/2" FPT outlet alignment is established when the 3/4" inlet joint is cemented and cannot be adjusted after cure. Allow adequate cure time before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Simultaneously changes direction, transitions from socket to threaded construction, and steps down from a 3/4" all-socket distribution run to a 1/2" male-threaded solenoid valve inlet, pressure regulator connection, drip manifold component, or zone control valve in residential and light commercial irrigation systems where all three transitions must occur at the same compact fitting location — the most efficient single-fitting solution for the common scenario of a 3/4" socket irrigation main turning 90 degrees to supply a 1/2" threaded valve or manifold component
• Drip & Micro-Irrigation Systems — Provides the standard combined turn-and-transition-and-reduce junction where a 3/4" socket distribution header must simultaneously change direction and supply a 1/2" male-threaded drip manifold inlet, pressure regulator, filter housing port, or zone valve body in compact drip system assemblies where the direction change, socket-to-thread transition, and size reduction must all occur at the same fitting location without three separate inline fittings
• Commercial Plumbing — Simultaneously redirects, transitions from socket to threaded construction, and reduces a 3/4" socket distribution main to a 1/2" male-threaded fixture supply valve, equipment feed connection, or dedicated service component in commercial building water distribution systems where the direction change, material transition, and size reduction must occur at the same compact branch supply fitting location
• Industrial Process Piping — Provides a compact combined turn, socket-to-thread transition, and size reduction at 3/4" socket distribution run direction change points where 1/2" male-threaded instrument connections, sampling valves, chemical injection ports, and small-bore service components must be supplied in a single fitting body in water treatment, chemical processing, and manufacturing facilities
• Chemical Handling — Delivers a corrosion-resistant combined direction change, socket-to-thread transition, and 3/4" to 1/2" size reduction at turn locations in 3/4" socket chemical feed distribution assemblies where 1/2" male-threaded injection ports, metering component inlets, and service valves must be incorporated at the 90-degree turn point without three separate fittings in systems conveying acids, caustics, and fertilizer solutions
• Water Treatment & Aquaculture — Used at 90-degree turn-and-reduce points in 3/4" all-socket distribution assemblies where the downstream 1/2" male-threaded component must simultaneously receive a direction change and socket-to-thread transition with NSF/ANSI 61 compliance required throughout
