Tee, Slip x Slip x FPT PVC Schedule 80 1-1/4" (802-012)

The 802-012 is a 1-1/4-inch Schedule 80 PVC tee with slip (socket) connections on both run ends and a 1-1/4-inch female pipe thread (FPT) connection on the branch outlet. All three ports are the same 1-1/4-inch nominal size — this is a straight tee, not a reducing fitting. The distinguishing design characteristic is the mixed connection type: where both run ends are permanently solvent welded into the pipe run, the branch is female NPT threaded, accepting and releasing male NPT fittings, valve bodies, and equipment connections as needed over the system's service life without disturbing the solvent welded mainline on either side.

The full-size 1-1/4-inch FPT branch is a critical distinction from reducing tees where a smaller threaded branch serves instrumentation or injection purposes. At 1-1/4-inch NPT, the branch on the 802-012 carries the same nominal flow capacity as the run — this is a full-flow service branch, suited for isolation valve assemblies, pump connections, bypass loops, equipment supply lines, and secondary distribution branches where the full pipe size must be maintained at the branch while keeping that connection threaded and serviceable. The slip x slip x FPT architecture cleanly separates the permanent fixed-installation elements of the system from the serviceable, reconfigurable branch connection in a single fitting body.

The two slip run ends accept standard 1-1/4-inch Schedule 80 PVC pipe for solvent weld assembly, creating permanent, pressure-rated joints structurally integral to the mainline pipe run. The 1-1/4-inch FPT branch accepts standard male NPT fittings, nipples, valves, and adapters directly — assembled with PTFE thread tape or appropriate thread sealant — and can be broken and remade independently without cutting into the solvent welded run. Isolation valves threaded into the branch can be removed for service or replacement, bypass assemblies can be reconfigured, and equipment connections can be changed out, all without affecting the permanently routed mainline.

Schedule 80 wall thickness provides the higher pressure rating and mechanical strength required for industrial chemical feed, process piping, and utility water systems. Gray PVC delivers broad chemical resistance to acids, alkalis, salts, and many industrial process fluids with no corrosion risk in wet or chemically aggressive environments. The slip ends conform to ASTM D2467 standards for Schedule 80 PVC socket fittings; the FPT branch conforms to ASTM D2464 for Schedule 80 PVC threaded fittings. Thread form conforms to ANSI/ASME B1.20.1 for NPT compatibility across manufacturers.

Specifications:

Pressure rating is for water service at 73°F. Derate for elevated temperatures and aggressive chemical service per manufacturer guidelines. Use PTFE thread tape or appropriate thread sealant on all male NPT connections threading into the FPT branch — do not overtighten male threaded fittings into PVC female threads.

Industries & Applications:

The 802-012 Schedule 80 tee serves industrial, chemical, and process piping applications wherever a 1-1/4-inch Schedule 80 PVC mainline requires a full-size, full-flow threaded branch connection for valve assemblies, equipment supply, or serviceable secondary distribution:

• Chemical Processing & Water Treatment — Full-size threaded branch connections on 1-1/4-inch chemical feed, chlorination, acid dosing, and reagent distribution headers where an isolation valve, check valve, or bypass assembly threads directly into the FPT branch and must be removable for service or replacement without cutting into the solvent welded mainline
• Valve & Isolation Assemblies — Tee bodies supporting threaded isolation valves, ball valves, gate valves, and check valves on 1-1/4-inch Schedule 80 process and utility lines where the valve is installed in the branch position for system isolation, bypass, or flow control and must be serviceable and replaceable over the system's life
• Pump & Equipment Bypass Lines — Full-size bypass branch connections on 1-1/4-inch pump suction and discharge headers where a threaded bypass valve assembly allows flow to be diverted around equipment for maintenance without permanently branching the mainline into a second fixed solvent weld run
• Industrial Process Piping — Secondary distribution branch connections and serviceable takeoffs on 1-1/4-inch reagent distribution and process utility headers where the branch must maintain full nominal pipe size capacity and the mixed connection architecture keeps the branch independently serviceable from the fixed mainline
• Agricultural & Irrigation Systems — Full-size serviceable branch connections on 1-1/4-inch pressurized irrigation mains and pump discharge lines where threaded zone control valves, filter station inlets, and flow control equipment are installed in the branch position and require periodic removal for service, cleaning, or seasonal maintenance
• Municipal & Commercial Plumbing — Branch valve and equipment connections on 1-1/4-inch Schedule 80 utility water and service lines where threaded isolation and service valves are installed at branch tee positions for system maintainability and where Schedule 80 pressure ratings are specified by code or engineer
• HVAC & Cooling Systems — Full-size threaded branch connections on 1-1/4-inch chemical treatment feed lines and condenser water piping where bypass valve assemblies, treatment equipment connections, and service branches are installed as threaded components on permanently routed solvent weld mains
• Semiconductor & Electronics Manufacturing — Serviceable branch connections on 1-1/4-inch ultra-pure water and chemical distribution lines where the threaded branch accommodates inline equipment, flow control valves, and instrumentation connections that require periodic access or replacement without disturbing the fixed pipe run
