Male Adapter, MPT x Slip PVC Schedule 40 1/2" (436-005)

This 1/2" Schedule 40 PVC Male Adapter (MPT x Slip) provides a direct straight-through transition from a 1/2" PVC socket pipe run to a 1/2" 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 is the smallest confirmed full-size entry in the 436 series and the highest-pressure rated — carrying approximately 600 psi at 73°F — making it well-suited for drip irrigation manifold terminations, instrument supply line connections, chemical injection system interfaces, and compact 1/2" service line termination applications where a socket supply run must terminate at a male-threaded terminal for threading into a female-threaded downstream port, valve body, equipment connection, or manifold FPT inlet.

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. The 1/2" MPT outlet threads directly into any standard 1/2" FPT or FIP female-threaded valve body inlet, manifold port, filter housing female-threaded connection, pump port, tee branch FPT outlet, or equipment female-threaded connection for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. This MPT x Slip configuration is the standard straight-through approach to terminating a 1/2" socket pipe run at a male-threaded terminal — the correct choice whenever the downstream connection is a female-threaded port requiring a male thread to seat into it and the pipe run continues inline without a direction change at the termination point. The male adapter is the confirmed functional inverse of the 1/2" female adapter (435-005 confirmed in the immediately preceding session entry) — where the 435-005 provides a female-threaded outlet for receiving a male-threaded component off a socket run, the 436-005 provides a male-threaded outlet for threading into a 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 (use 436-005 MPT) or a male-threaded component presenting a thread (use 435-005 FPT). At 1/2", the critical distinction between 436-005 and 436-073 (1/2" Slip x 3/8" MPT Reducing Male Adapter, confirmed in this catalog session) is the MPT outlet size — 436-005 maintains the full 1/2" diameter at both ends while 436-073 steps down to a smaller 3/8" MPT outlet for specific legacy instrument or flow meter connections; 436-005 is the correct choice when the downstream female-threaded port is 1/2" NPT while 436-073 is the correct choice when the downstream port is 3/8" NPT. At 1/2", this adapter most commonly terminates all-socket drip irrigation supply runs at 1/2" FPT solenoid valve body inlets, filter housing female-threaded entry ports, and manifold FPT connections; terminates 1/2" socket instrument supply runs at female-threaded instrument port connections, sampling valve FPT inlets, and sensor body female-threaded ports; and terminates 1/2" socket chemical feed lines at female-threaded injection system ports, metering valve FPT inlets, and dosing system female-threaded connections — wherever the downstream female-threaded port is inline with the 1/2" socket supply run and requires a 1/2" male NPT thread at the straight-through pipe run end.

Rated to approximately 600 psi at 73°F (governed by the 1/2" slip end) — the highest confirmed pressure rating in the 436 series — this adapter is suited for standard commercial and light industrial water distribution, irrigation, instrument service, and chemical injection 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. On the 1/2" 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 1/2" require hand-tight plus one to two turns; at 1/2", the compact male thread is more susceptible to overtorque stress than at larger sizes. Allow adequate cure time on the cemented joint before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Drip & Micro-Irrigation Systems — Terminates 1/2" socket drip emitter supply runs, zone distribution laterals, and manifold approach pipe sections at solenoid valve body FPT inlets, filter housing female-threaded entry ports, and manifold FPT component connections in residential and light commercial drip and micro-irrigation assemblies where the downstream female-threaded port is inline with the socket pipe run and must receive a 1/2" male NPT thread at the straight-through pipe run end
• Irrigation & Water Distribution — Transitions 1/2" socket pipe runs to male-threaded terminals at solenoid valve FPT inlets, filter housing female-threaded ports, pump connections, and zone supply manifold FPT entry points in residential and light commercial irrigation systems where the downstream female-threaded port is aligned inline with the 1/2" socket supply run at the pipe run termination
• Instrument & Process Piping — Terminates 1/2" socket instrument supply runs at female-threaded instrument port connections, sampling valve FPT inlets, sensor body female-threaded ports, and flow measurement device FPT connections in manufacturing, water treatment, and laboratory facilities where the downstream female-threaded instrument component is inline with the socket supply run and requires a 1/2" male NPT thread at the straight-through pipe run end
• Chemical Handling — Provides a corrosion-resistant straight-through socket-to-male-thread transition at 1/2" chemical feed pipe run terminations in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal adapters where a female-threaded injection component, metering valve FPT inlet, or dosing system female-threaded connection is inline with the 1/2" socket supply run at the pipe end
• Water Treatment & Aquaculture — Used at 1/2" socket pipe run straight-through termination points where female-threaded pump connections, filter housing FPT inlets, treatment equipment ports, and chemical dosing component female-threaded stubs must receive the socket run with NSF/ANSI 61 compliant socket-to-male-thread transition inline at the pipe run end
• Commercial Plumbing — Transitions 1/2" socket dedicated service supply runs, branch supply laterals, and fixture approach pipe sections to male-threaded terminals at female-threaded service valve inlets, equipment FPT feed connections, and instrument tap female-threaded stubs in commercial building water distribution systems where the downstream female-threaded component is inline with the socket supply run at the pipe run termination
