Male Adapter, MPT x Slip PVC Schedule 40 3/4" (436-007)

This 3/4" Schedule 40 PVC Male Adapter (MPT x Slip) provides a direct transition from a 3/4" PVC socket pipe run to a 3/4" male NPT-threaded outlet, combining a solvent-cement socket inlet and a male-threaded outlet in a single compact fitting body. Constructed in white Schedule 40 PVC, it is the highest-demand entry in the 436 series — the standard pipe-to-equipment male-threaded transition at the dominant residential and light commercial irrigation valve station and distribution assembly diameter — offering the corrosion resistance and chemical compatibility required wherever a 3/4" socket pipe run must terminate at a male-threaded outlet for threading into a female-threaded valve body, pump port, filter housing inlet, manifold connection, or equipment port.

The 3/4" slip socket inlet accepts 3/4" PVC pipe for a permanent solvent-cement bond, anchoring the fitting to the upstream socket distribution assembly. The 3/4" MPT outlet threads directly into any standard 3/4" FPT or FIP female-threaded valve body inlet, pump port, filter housing female-threaded connection, manifold FPT port, equipment connection, or tee branch FPT outlet for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. This MPT x Slip configuration is the standard approach to terminating a 3/4" socket pipe run at a female-threaded receptacle — the correct choice whenever the downstream port is a female-threaded connection requiring a male thread to seat into it. The male adapter is the confirmed functional inverse of the 3/4" female adapter (435-007 confirmed in this catalog session) — where the 435-007 provides a female-threaded outlet for receiving a 3/4" male-threaded component off a socket run, the 436-007 provides a male-threaded outlet for threading into a 3/4" female-threaded port off the same socket run; the correct choice between them is determined entirely by whether the downstream connection is a female-threaded port receiving a male thread (use 436-007 MPT) or a male-threaded component presenting a male thread (use 435-007 FPT). At 3/4", the full-size 436-007 should not be confused with the confirmed 436-074 (3/4" MPT x 1/2" Slip, confirmed in this session), which shares the same 3/4" MPT outlet but has a smaller 1/2" slip socket inlet serving the specific irrigation component conversion application; 436-007 is the correct choice when the upstream socket pipe run is also 3/4" rather than the smaller 1/2" of 436-074. At 3/4", this adapter most commonly terminates all-socket irrigation mainline and distribution pipe runs at pump discharge female-threaded connections, filter housing FPT inlets, valve body female-threaded ports, and zone manifold female-threaded entry connections where the upstream pipe run is all-socket 3/4" PVC and the downstream female-threaded port must receive a 3/4" male thread — the highest-demand pipe-to-equipment male-threaded transition at the dominant residential irrigation and light commercial distribution diameter.

Rated to approximately 480 psi at 73°F (governed by the 3/4" slip end), this adapter is suited for standard commercial and light industrial water distribution and irrigation service 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. On the 3/4" MPT end, use a quality pipe thread sealant or PTFE tape before threading into the receiving female port. Avoid over-torquing — PVC male threads at 3/4" require hand-tight plus one to two turns; excessive torque can crack the fitting body or damage the receiving female threads. Allow adequate cure time on the cemented joint before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Terminates 3/4" PVC socket mainline, lateral, and distribution pipe runs at pump discharge female-threaded connections, filter housing FPT inlets, valve body female-threaded ports, and zone manifold female-threaded entry connections in residential, light commercial, and agricultural irrigation systems where the downstream female-threaded port must receive a 3/4" male NPT thread at the end of the all-socket pipe run — the highest-demand pipe-to-equipment male-threaded transition at the dominant residential irrigation distribution diameter
• Commercial Plumbing — Transitions 3/4" socket PVC distribution mains to male-threaded terminals at pump body female-threaded connections, valve body FPT inlets, equipment female-threaded ports, and service connection stubs in commercial building water distribution systems where the downstream female-threaded port requires a 3/4" male thread at the pipe run termination
• Pump Station Assemblies — Provides male-threaded terminals at 3/4" socket pump suction and discharge pipe run terminations, bypass line female-threaded stubs, and valve station FPT inlet connections in pump station installations where the pump body, valve, or equipment presents a 3/4" female-threaded port at the pipe-to-equipment interface requiring a male thread
• Industrial Process Piping — Transitions 3/4" socket process water distribution pipe runs to male-threaded terminals at pump FPT inlets, valve body female-threaded connections, flow meter ports, and equipment interfaces in water treatment, chemical processing, and manufacturing facilities where all-socket downstream assemblies must deliver a 3/4" male thread to female-threaded process equipment connections
• Water Treatment & Aquaculture — Used at pump suction connections, filter housing FPT inlets, treatment equipment female-threaded ports, and recirculating system female-threaded component interfaces where a 3/4" socket pipe run must terminate at a male-threaded connection with NSF/ANSI 61 compliance required throughout the assembly
• Chemical Handling — Provides a corrosion-resistant socket-to-male-thread transition at 3/4" pipe run terminations in chemical distribution assemblies and pump station socket piping conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal adapters where the downstream female-threaded equipment or manifold port must receive a 3/4" male NPT thread off the all-socket pipe run
