Female Adapter, Slip x FPT PVC Schedule 80 2" (835-020)

The 835-020 is a 2" PVC Schedule 80 female adapter with a slip (socket) inlet and a female pipe thread (FPT) outlet, designed to transition a solvent-welded PVC pipeline to a female-threaded connection point. The slip inlet accepts a standard 2" PVC pipe end joined with solvent cement and primer per ASTM D2564, while the FPT outlet provides a 2" NPT female-threaded port that accepts any standard male-threaded (MPT) pipe, fitting, valve, or equipment connection — no solvent welding required at the threaded end.

Manufactured from rigid, dark gray PVC compound conforming to ASTM D1784 cell classification requirements, the Schedule 80 wall construction delivers higher pressure ratings and greater mechanical strength than Schedule 40 equivalents at the same pipe size. This makes the 835-020 the correct choice for high-pressure chemical lines, industrial process piping, and any Schedule 80 system where the transition point between a solvent-welded run and a threaded connection must maintain full Schedule 80 pressure integrity throughout.

The slip x FPT female adapter is one of the most commonly used transition fittings in PVC piping systems, bridging the gap between permanent solvent-welded pipe runs and the threaded connections required at valves, pumps, gauges, equipment nozzles, and instrumentation ports. The FPT outlet accepts a male-threaded fitting or pipe end, with PTFE thread tape or appropriate thread sealant applied to the male threads before assembly to ensure a leak-resistant seal. The threaded connection at the outlet remains serviceable — valves, instruments, and threaded components can be removed and replaced without disturbing the upstream solvent-welded pipeline.

Industries & Applications:

• Industrial Process Piping — Transitioning solvent-welded Schedule 80 PVC runs to threaded connections at valves, pumps, instrumentation ports, and equipment nozzles in high-pressure process and chemical systems
• Chemical Processing — Corrosion-resistant slip-to-thread transitions in acid, caustic, and aggressive fluid service where all-PVC construction eliminates metal corrosion and galvanic compatibility concerns
• Municipal Water & Wastewater — Pump station and treatment facility piping where a permanent solvent-welded mainline must transition to a serviceable threaded connection at valves, gauges, or equipment tie-ins
• Irrigation & Agriculture — Transitioning solvent-welded high-pressure mainline pipe to threaded valve, filter, and regulator connections in large-scale pressurized irrigation systems
• HVAC & Mechanical — Connecting solvent-welded chilled water and condenser water pipe runs to threaded mechanical equipment, balancing valves, and instrumentation in commercial mechanical rooms
• Aquaculture & Water Treatment — Slip-to-thread transitions in recirculating system manifolds where downstream threaded components require periodic removal, inspection, or replacement
