Female Adapter, Slip x FPT PVC Schedule 40 1/2" (435-005)

This 1/2" Schedule 40 PVC Female Adapter (Slip x FPT) provides a direct straight-through transition from a 1/2" PVC socket pipe run to a 1/2" female NPT-threaded outlet, combining a solvent-cement socket inlet and a female-threaded outlet in a single compact fitting body. Constructed in white Schedule 40 PVC, it is the smallest confirmed entry in the 435 series and the highest-pressure rated — carrying approximately 600 psi at 73°F — making it well-suited for the instrument manifold terminations, chemical injection line connections, solenoid valve body MPT inlet interfaces, and compact 1/2" service line termination applications that dominate at this standard small-bore service diameter.

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" FPT outlet accepts any standard 1/2" male NPT-threaded fitting, solenoid valve inlet, instrument connection, pressure gauge, sampling valve, chemical injection nipple, or equipment port for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. This Slip x FPT configuration is the standard straight-through approach to terminating a 1/2" socket pipe run at a female-threaded receptacle — the correct choice whenever the downstream component presents a 1/2" male NPT thread that must seat into a female port and the pipe run continues inline without a direction change at the termination point. The female adapter is the functional inverse of the 1/2" male adapter (436-005 if stocked) — where the 436-005 provides a male-threaded outlet for threading into a female-threaded port off a socket run, the 435-005 provides a female-threaded outlet for receiving a male-threaded component 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 (use 435-005 FPT). At 1/2", the critical distinction between 435-005 (straight-through inline, no direction change) and the confirmed 407-005 (Slip x FPT 90 Degree Elbow, confirmed in the immediately preceding session entry) is the body geometry — 435-005 terminates the socket run straight-through at a female-threaded outlet inline with the pipe run axis, while 407-005 provides the same Slip x FPT transition at a 90-degree turn; the correct choice depends solely on whether the downstream male-threaded component is aligned with the pipe run axis (435-005) or perpendicular to it (407-005). At 1/2", this adapter most commonly terminates 1/2" all-socket drip irrigation supply runs at solenoid valve body MPT inlets, pressure regulator male-threaded connections, and filter housing MPT ports; terminates 1/2" socket instrument supply runs at male-threaded instrument connections, sampling valve inlets, and sensor ports; and terminates 1/2" socket chemical feed lines at male-threaded injection component inlets, metering valve bodies, and dosing system connections — wherever the downstream component is inline with the 1/2" socket supply run and presents a 1/2" male NPT thread requiring a female-threaded receptacle 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 435 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" FPT end, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating downstream component before engagement. Avoid over-torquing — PVC female threads require hand-tight plus one to two turns at 1/2". Allow adequate cure time on the cemented joint before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

• Irrigation & Water Distribution — Transitions 1/2" socket pipe runs to female-threaded receptacles at solenoid valve MPT inlets, pump port connections, filter housing male-threaded ports, and zone supply manifold component stubs in residential and light commercial irrigation systems where the downstream male-threaded component is aligned inline with the 1/2" socket supply run at the pipe run end
• Instrument & Process Piping — Terminates 1/2" socket instrument supply runs at male-threaded instrument connections, sampling valve inlets, pressure gauge ports, sensor connections, and flow measurement device male-threaded stubs in manufacturing, water treatment, and laboratory facilities where the downstream instrument component is inline with the socket supply run and presents a 1/2" male NPT thread requiring a straight-through female-threaded receptacle at the socket run end
• Chemical Handling — Provides a corrosion-resistant straight-through socket-to-female-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 male-threaded injection component, metering valve, or dosing system connection is inline with the 1/2" socket supply run at the pipe run end
• Water Treatment & Aquaculture — Used at 1/2" socket pipe run straight-through termination points where male-threaded pump connections, filter housing MPT inlets, treatment equipment ports, and chemical dosing component stubs must receive the socket run with NSF/ANSI 61 compliant socket-to-female-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 female-threaded receptacles at male-threaded service valve inlets, equipment feed connections, and instrument tap stubs in commercial building water distribution systems where the downstream male-threaded component is inline with the 1/2" socket supply run at the pipe run termination
