Male Adapter, MPT x Slip PVC Schedule 40 2" (436-020)

This 2" Schedule 40 PVC Male Adapter (MPT x Slip) provides a direct transition from a 2" PVC socket pipe run to a 2" 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 offers the corrosion resistance and chemical compatibility required across a wide range of commercial plumbing, irrigation, and light industrial applications where a 2" socket pipe run must terminate at a male-threaded outlet for connection to a female-threaded valve, pump port, filter housing, equipment inlet, or threaded pipe run without additional transition hardware.

The 2" slip socket inlet accepts 2" PVC pipe for a permanent solvent-cement bond, anchoring the fitting to the upstream socket distribution assembly. The 2" MPT exterior threads directly into any standard 2" FPT or FIP female-threaded fitting, valve body, pump port, filter housing, equipment connection, or manifold FPT port 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 transitioning from a socket pipe run into a male-threaded outlet — the correct choice whenever the downstream component presents a female-threaded port that must receive a male NPT thread. The male adapter is the functional inverse of the female adapter (435-020, confirmed in this catalog session) — where the 435-020 provides a female-threaded outlet off a socket run for receiving a male-threaded component, the 436-020 provides a male-threaded outlet off a socket run for threading into a female-threaded port; both accomplish the socket-to-thread material transition at the pipe-to-equipment interface but in opposite threaded orientations, and the correct choice between them is determined entirely by the thread orientation of the downstream component. At 2", this adapter is most commonly specified at pump discharge and suction connections to female-threaded pump ports, valve body FPT inlets, filter housing female-threaded ports, equipment female-threaded connections, and distribution manifold FPT ports where the downstream component presents a female NPT thread and the upstream pipe run is all-socket PVC.

Rated to approximately 280 psi at 73°F (governed by the 2" slip end), this adapter is suited for standard commercial and light industrial water distribution and irrigation service within its pressure class. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal adapters in moisture-prone or chemically active environments. 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, using a primer appropriate for the pipe and fitting schedule. Insert pipe fully into the socket and maintain a quarter-turn during assembly for even cement distribution. On the 2" MPT end, use a quality pipe thread sealant or PTFE tape before threading into the receiving female port. Avoid over-torquing — PVC threads require hand-tight plus one to two turns; at 2", use an appropriate pipe wrench on the fitting hex flats if present, and avoid excessive leverage that could crack the fitting body or strip the receiving female threads. Allow adequate cure time on the cemented joint before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Terminates 2" PVC socket mainline pipe runs at female-threaded pump discharge ports, valve body FPT inlets, filter housing female-threaded connections, and zone manifold FPT ports in agricultural and municipal irrigation systems where the downstream component presents a female NPT thread requiring a male-threaded outlet at the end of the all-socket pipe run
• Commercial Plumbing — Transitions 2" socket PVC distribution mains to male-threaded outlets at pump connection female-threaded ports, valve body FPT inlets, equipment female-threaded connections, and riser female-threaded receptacles in commercial building water distribution systems where the downstream threaded component requires a male NPT thread at the pipe run termination
• Pump Station Assemblies — Provides male-threaded outlets at 2" socket pump suction and discharge pipe run terminations, bypass line female-threaded stub connections, and valve station FPT inlet connections in pump station installations where the pump body, valve, or equipment presents a female NPT thread at the pipe-to-equipment interface
• Industrial Process Piping — Transitions 2" socket process water distribution pipe runs to male-threaded outlets at pump inlets, valve body FPT connections, flow meter female-threaded ports, and equipment interfaces in water treatment, chemical processing, and manufacturing facilities where the all-socket downstream assembly must connect to female-threaded process equipment ports
• Water Treatment & Aquaculture — Used at pump suction connections, filter housing female-threaded inlets, treatment equipment FPT ports, and recirculating system female-threaded component interfaces where a 2" socket pipe run must terminate at a male-threaded outlet with NSF/ANSI 61 compliance required throughout the assembly
• HVAC & Mechanical Systems — Transitions 2" socket PVC pipe runs to male-threaded outlets at pump connection female-threaded ports, cooling tower supply FPT inlets, chilled water distribution equipment female-threaded connections, and chemically treated water system component FPT interfaces within the Schedule 40 pressure class
