Female Adapter, Slip x FPT PVC Schedule 80 1/2" (835-005)

This 1/2" Schedule 80 PVC Female Adapter (Slip x FPT) provides a direct, reliable transition from a Schedule 80 PVC socket pipe run to any standard 1/2" male NPT-threaded fitting, nipple, valve, pump port, or equipment connection in industrial, chemical, and commercial piping systems. Constructed in dark gray Schedule 80 PVC, it delivers the elevated wall thickness and pressure capacity required in demanding installations where standard Schedule 40 fittings are insufficient and where a corrosion-resistant socket-to-female-thread transition is needed at small-diameter service connections throughout an all-Schedule-80 assembly.

The slip socket end accepts a 1/2" PVC pipe for a permanent solvent-cement bond, while the FPT interior accepts any standard 1/2" male NPT-threaded pipe end, nipple, or fitting for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. This Slip x FPT configuration is the inverse of the male adapter (836 series) and serves a distinct transition function — where the male adapter (836-005) terminates a Schedule 80 PVC pipe run with a male thread that inserts into a female port, the female adapter terminates a Schedule 80 PVC pipe run with a female thread that receives a male-threaded component. This makes the female adapter the correct choice when the downstream threaded component presents a male NPT end — such as a threaded nipple stub, pump discharge nipple, male-threaded valve stem, instrument connection, chemical injection port, or male-threaded equipment fitting — that must be received rather than engaged from the outside. At 1/2", this adapter is among the most frequently specified sizes in Schedule 80 transition applications, appearing throughout chemical feed assemblies, instrument distribution manifolds, pump discharge piping, and small-diameter process piping installations where the elevated pressure rating and chemical resistance of Schedule 80 are required at every transition point in the system.

Rated to approximately 850 psi at 73°F (governed by the 1/2" slip end), this adapter is well-suited for demanding pressure service across a broad range of industrial, chemical, and commercial fluid handling applications. Its PVC composition provides excellent resistance to acids, bases, salts, and chlorinated water, making it a durable long-term choice in corrosive environments where metal fittings would degrade. NSF/ANSI 61 listing confirms suitability for potable water contact, including use in drinking water distribution and treatment systems.

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 across the joint surface. On the FPT end, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating component before engagement. 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:

• Industrial Process Piping — Terminates 1/2" Schedule 80 PVC socket pipe runs at male-threaded pump discharge nipples, valve stems, instrument connections, chemical injection ports, and equipment fittings in chemical processing, water treatment, and manufacturing facilities where the downstream threaded component presents a male NPT end requiring a female-threaded socket adapter at the pipe-to-thread interface
• Chemical Handling — Provides a corrosion-resistant socket-to-female-thread transition in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, particularly at chemical metering pump male-threaded discharge nipples, injection point stubs, and dosing manifold male-threaded connections where a receiving female thread is required at the Schedule 80 pipe end
• Commercial Plumbing — Connects 1/2" Schedule 80 PVC socket branch lines to male-threaded pressure gauges, backflow preventer connections, valve stems, and fixture supply fittings in high-pressure or exposed commercial building water supply systems where Schedule 80 socket construction is specified throughout the assembly
• Irrigation & Water Distribution — Transitions 1/2" Schedule 80 PVC socket lateral supply lines to male-threaded solenoid valve inlets, drip emitter manifold stubs, instrument connections, and filter housing male-threaded ports in high-pressure agricultural and municipal irrigation systems requiring Schedule 80 pressure ratings at small-diameter branch terminations
• Water Treatment & Aquaculture — Used at UV sterilizer male-threaded inlet stubs, chemical dosing pump discharge connections, filter housing male-threaded ports, and recirculating system instrument tap stubs where NSF/ANSI 61 compliance and Schedule 80 pressure capacity are required at 1/2" socket-to-thread transition points
• HVAC & Mechanical Systems — Connects 1/2" Schedule 80 PVC socket pipe runs to male-threaded sensor stubs, drain valve nipples, chemical feed equipment ports, and instrument connections on cooling tower distribution headers, chilled water service lines, and chemically treated water systems requiring elevated pressure ratings at small-diameter socket-to-thread transition points
