Tee, FPT x FPT x FPT PVC Schedule 80 2-1/2" (805-025)

The 2-1/2" PVC Schedule 80 Tee (FPT x FPT x FPT) is a heavy-duty thermoplastic tee fitting with female NPT threads on all three connections — both run ends and the branch outlet. Designed for fully threaded industrial PVC piping systems, this fitting accepts standard 2-1/2-inch male NPT threaded pipe, nipples, or adapters on each of its three ports, providing a branch takeoff point that is entirely threaded and entirely disassemblable without cutting, cementing, or disturbing any joint in the assembly.

The 805-025 is the 2-1/2-inch member of the 805-series all-FPT tee line, sitting directly below the previously described 805-030 (3-inch all-FPT tee) in the series. The design intent, system context, and specification rationale are consistent across the series — both fittings serve fully threaded Schedule 80 PVC assemblies where disassembly flexibility on all three ports is a deliberate design requirement. The distinction between the two sizes is the downstream application profile. Where the 3-inch all-FPT tee serves primary distribution branches, major equipment connections, and high-capacity threaded laterals, the 2-1/2-inch version serves moderate-flow threaded systems where 2-1/2 inches is the governing pipe size — pump bypass circuits, chemical feed distribution headers, strainer manifolds, secondary process supply lines, and industrial assemblies in the 2-1/2-inch size range that require the same fully threaded, fully serviceable construction that the all-FPT tee provides.

Within a fully threaded 2-1/2-inch Schedule 80 system, the FPT x FPT x FPT tee is the branch fitting — the point where the run divides and a lateral departs, with all three departure points remaining open to disassembly at any time. The run ends accept close nipples, pipe sections, union halves, or male adapters; the branch accepts the same range of 2-1/2-inch MPT components. The branch port can be closed with a threaded plug when not in active service and opened or reconfigured by threading in the appropriate fitting without disturbing the run connections. This modularity — the ability to change, cap, or replace any of the three connections independently — is the operational characteristic that distinguishes the all-FPT tee from a mixed slip/FPT configuration and drives its specification in systems designed for reconfiguration, periodic cleaning, regulatory inspection, or component replacement over time.

The 2-1/2-inch size carries a specific relevance in the all-FPT tee line. At this diameter, fully threaded PVC assemblies are practical and common in pump discharge circuits, chemical injection distribution manifolds, industrial strainer assemblies, and moderate-capacity process lines — environments where the pipe size is large enough to carry meaningful flow volumes and small enough to keep the threaded assembly manageable in terms of fitting weight, thread engagement torque, and the physical demands of assembly and disassembly in the field. The 2-1/2-inch all-FPT tee occupies the practical center of this range.

As established across the threaded Schedule 80 fitting descriptions in this catalog, Schedule 80 PVC provides the wall thickness that makes fully threaded PVC systems viable in industrial service. At each of the three FPT connections on this fitting, the Schedule 80 wall supports deeper thread engagement, greater material depth behind the thread form, and improved resistance to thread failure under sustained pressure, thermal cycling, and the cumulative torque of repeated assembly and disassembly cycles. Manufactured to ASTM D2467 standards and compatible with standard NPT threaded fittings throughout the 2-1/2-inch nominal pipe size range.

Industries & Applications:

• Chemical Processing & Distribution Manifolds — Used in fully threaded 2-1/2-inch Schedule 80 PVC chemical distribution lines where the tee provides a branch takeoff at a system junction that must remain disassemblable on all three ports — for chemical line cleaning, compatibility upgrades, pipe section replacement due to chemical degradation, or system reconfiguration between process campaigns
• Pump Bypass & Recirculation Circuits — Specified in pump discharge assemblies where a 2-1/2-inch fully threaded tee provides a branch point for a recirculation return, bypass circuit, or pressure relief connection — with all three ports threaded to allow the pump, bypass valve, and downstream line to be independently disconnected for service without cutting or disturbing any joint in the assembly
• Industrial Strainer & Filter Manifolds — Incorporated in strainer and filter manifold assemblies where a 2-1/2-inch all-FPT tee provides a branch point for a strainer bypass, differential pressure monitoring connection, or secondary filter circuit — the fully threaded configuration allowing the strainer body, bypass valve, and monitoring instruments to be individually removed for cleaning, element replacement, and recalibration
• Water & Wastewater Treatment — Applied in treatment plant process piping and chemical dosing systems where 2-1/2-inch Schedule 80 threaded assemblies require a branch takeoff that must remain fully accessible and disassemblable — at chemical feed distribution headers, recirculation branch points, and dosing equipment connection manifolds subject to routine maintenance, cleaning, and regulatory inspection
• Equipment Test Manifolds & Laboratory Systems — Specified in test bench manifolds, pilot plant systems, and laboratory process rigs where a 2-1/2-inch all-FPT tee provides a fully reconfigurable branch junction — allowing the manifold to be torn down, rebuilt, and reconfigured between test cycles without cutting or re-cementing any fitting in the assembly
• Industrial Irrigation & Agricultural Chemical Injection — Used in 2-1/2-inch Schedule 80 irrigation mains and chemical injection distribution headers where a fully threaded tee at the branch point allows the injection assembly, isolation valves, and supply fittings to be removed and replaced seasonally or during maintenance cycles without disturbing the run connections on either side of the tee body
