Female Adapter, Slip x FPT PVC Schedule 80 3" (835-030)

Blue Monster 76037 1-Step PVC Cement Clear (32OZ)

This 3" Schedule 80 PVC Female Adapter (Slip x FPT) provides a direct transition from a 3" Schedule 80 PVC socket pipe run to a 3" female NPT-threaded outlet, combining a solvent-cement socket inlet and a female-threaded outlet in a single compact fitting body. Constructed in dark gray Schedule 80 PVC, it delivers the elevated pressure performance and chemical resistance of Schedule 80 construction at the pipe-to-equipment threaded interface — the standard fitting for pump, valve, meter, and equipment connections at 3" nominal pipe size where a 3" Schedule 80 socket pipe run must terminate at a female-threaded receptacle for a 3" male-threaded component.

The 3" slip socket inlet accepts 3" Schedule 80 PVC pipe for a permanent solvent-cement bond, anchoring the fitting to the upstream 3" all-socket distribution assembly. The 3" FPT outlet accepts any standard 3" male NPT-threaded pipe end, nipple, valve body outlet, pump connection, 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 approach to terminating a 3" Schedule 80 socket pipe run at a female-threaded receptacle — the correct choice whenever the downstream component presents a 3" male NPT thread that must seat into a female port. The female adapter is the functional inverse of the 3" male adapter (836-030 if stocked) — where the 836-030 provides a male-threaded outlet for threading into a 3" female-threaded port off a socket run, the 835-030 provides a female-threaded outlet for receiving a 3" 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 receiving a male thread (use 836-030 MPT) or a male-threaded component presenting a thread to a female receptacle (use 835-030 FPT). At 3", this adapter most commonly terminates 3" all-socket Schedule 80 pump suction and discharge pipe runs at flanged or threaded pump body MPT connections; terminates 3" socket runs at large valve body MPT inlets and isolation valve threaded connections; terminates at filter housing and strainer male-threaded ports; and transitions large-diameter socket pipe runs to male-threaded meter bodies, chemical injection equipment, and major process equipment interfaces in large commercial and industrial systems where Schedule 80 pressure performance and chemical resistance are required at the socket-to-threaded interface. The Schedule 40 counterpart (435-030 if stocked) serves the same pipe-to-equipment female-threaded transition function at lower pressure ratings and white Schedule 40 color — 835-030 is the correct choice wherever Schedule 80 pressure ratings and chemical resistance are required at the 3" pipe run termination.

Apply medium-bodied solvent cement appropriate for 3" nominal socket joints to both the pipe end and fitting socket per ASTM D2564 procedures, using a primer appropriate for Schedule 80 pipe and fittings. Insert pipe fully into the socket and maintain a quarter-turn during assembly. On the 3" 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 at 3" can crack under excessive torque; hand-tight plus one to two turns is the standard engagement range. 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:

• Pump Station Assemblies — Industrial & Municipal — Terminates 3" Schedule 80 all-socket pump suction and discharge pipe runs at pump body MPT connections, pump station valve body male-threaded inlets, and bypass line male-threaded stubs in industrial and municipal pump station installations where Schedule 80 pressure performance is required at the 3" pipe-to-pump-equipment female-threaded transition and the downstream pump, valve, or equipment component presents a 3" male NPT thread at the socket pipe run end
• Large-Scale Irrigation — Agricultural & Municipal — Terminates 3" Schedule 80 socket primary supply and pump discharge pipe runs at valve body MPT inlets, filter housing male-threaded ports, and primary manifold male-threaded stubs in large agricultural and municipal irrigation systems where Schedule 80 construction and all-socket-to-threaded transition at 3" nominal are required at pump station and primary valve station interfaces
• Industrial Process Piping — Transitions 3" Schedule 80 all-socket process water distribution, cooling water supply, and chemical distribution pipe runs to female-threaded receptacles at pump MPT inlets, valve body male-threaded connections, flow meter male-threaded ports, and major process equipment interfaces in water treatment, chemical processing, and manufacturing facilities where Schedule 80 chemical resistance and pressure performance are required at the 3" socket-to-threaded interface
• Chemical Handling — Provides a corrosion-resistant socket-to-female-thread transition at 3" pipe run terminations in chemical distribution, pump station, and transfer line socket assemblies conveying acids, caustics, fertilizer solutions, and other chemically aggressive fluids where Schedule 80 chemical resistance is required at the 3" male-threaded equipment or component interface and the downstream component presents a 3" male NPT thread
• Water Treatment & Potable Water Systems — Terminates 3" Schedule 80 socket filter influent and effluent runs, primary distribution pipe sections, and treatment system supply pipe ends at male-threaded treatment equipment ports, isolation valve MPT inlets, and flanged-to-threaded transition component stubs in large water treatment plants where NSF/ANSI 61 compliance and Schedule 80 performance are required at the 3" socket run termination
• Municipal Water Distribution — Transitions 3" Schedule 80 socket transmission and primary distribution pipe runs to female-threaded receptacles at valve body MPT connections, pressure reducing valve inlets, and metering equipment male-threaded ports in municipal water distribution systems where Schedule 80 construction and all-socket-to-threaded transition are required at 3" in-line valve and equipment interface points
