Female Adapter, Slip x FPT PVC Schedule 40 8" (435-080)

The 8" PVC Schedule 40 Female Adapter (Part No. 435-080) is a large-diameter, white-body fitting designed to transition a solvent-cemented Schedule 40 PVC pipe run into a female pipe thread (FPT) connection. The slip (socket) inlet accepts a solvent-cement joint to the pipe end, creating a permanent, leak-resistant bond on the pipe side, while the FPT outlet receives a male-threaded pipe, fitting, or equipment connection — making this adapter the correct specification wherever a cemented PVC system must interface with a threaded component.

Female adapters are a fundamental transition fitting in PVC piping systems, and at 8" this SKU serves the large-diameter end of the Schedule 40 lineup where the fitting itself is a substantial component. The 8" FPT outlet is most commonly used to connect to large-bore threaded valves, pumps, meters, flanged equipment with a threaded transition nipple, or other system components that terminate in a male NPT thread. By combining the slip and FPT connections in a single fitting, the female adapter eliminates the need for a separate coupling and threaded fitting in series, keeping the transition compact and minimizing potential leak points.

At 8", Schedule 40 white PVC is a common specification for gravity-flow, low-to-moderate pressure, and non-chemical-aggressive applications in municipal infrastructure, commercial construction, and large-scale irrigation. Where higher pressure ratings or chemical resistance are required at the same diameter, Schedule 80 gray PVC would be the appropriate upgrade — buyers specifying 8" in Schedule 40 have typically confirmed the pressure and chemical requirements are within Schedule 40's operating range for the application.

Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2466 dimensional standards and is compatible with Schedule 40 PVC pipe and solvent cements meeting ASTM D2564. Threads conform to ANSI B1.20.1 NPT.
