Tee, FPT x FPT x FPT PVC Schedule 80 1-1/4" (805-012)

The 805-012 is a 1-1/4" PVC Schedule 80 tee in an all-FPT (Female Pipe Thread x Female Pipe Thread x Female Pipe Thread) configuration, providing a standard 90-degree branch connection across three equal 1-1/4" threaded ports. All three ports accept 1-1/4" MPT fittings, nipples, valves, or equipment connections — making this a straightforward, fully threaded solution for T-branch connections in Schedule 80 PVC systems where solvent cement is impractical or where the system requires the ability to disassemble and reconfigure at the tee over time.

The all-threaded construction makes the 805-012 particularly well-suited for field assembly, system modifications, and installations connecting to threaded equipment ports that cannot accept solvent-welded fittings. Each port can be independently assembled and tightened, and the tee can serve as a junction point where two independently built threaded sub-assemblies meet — with the third port used for a branch valve, instrument connection, or capped outlet.

Unlike an all-slip tee, which creates a fully permanent assembly once cemented, the 805-012 allows individual ports to be broken loose, modified, or redirected with appropriate tools. This makes it a practical choice in systems that evolve over time — adding branch connections, swapping out valves, or reconfiguring distribution headers without requiring pipe cuts or new cement joints.

Schedule 80's thicker wall construction delivers higher pressure ratings and stronger resistance to mechanical stress and chemical exposure than Schedule 40, making this tee appropriate for demanding industrial, chemical, and process environments where the heavier wall is warranted. The gray color is the standard Schedule 80 identifier, providing clear visual differentiation from white Schedule 40 components in mixed systems.

Thread sealing follows standard practice for PVC threaded fittings: apply PTFE thread tape or a compatible PVC-rated thread sealant to the male threads of all mating fittings before assembly. Avoid petroleum-based pipe dopes, which can degrade PVC over time. Thread each fitting by hand first to confirm engagement, then snug with a strap wrench — do not over-tighten, as excessive torque risks cracking PVC female threads.

Industries & Applications:

The 805-012 all-threaded tee is used across any Schedule 80 system requiring a full-bore threaded branch connection in a 1-1/4" line:

• Industrial Processing — Threaded branch connections in process piping headers, equipment feed lines, and utility supply runs where all-threaded construction allows field assembly, system modifications, and disassembly without pipe cuts or cement joints
• Chemical Handling — Branch connections in acid, alkali, and reagent distribution systems where threaded fittings allow periodic reconfiguration, valve swaps, and equipment changes without disturbing the surrounding piping — particularly at injection points, sampling branches, and chemical feed headers
• Water & Wastewater Treatment — Threaded T-branch connections at pump stations, chemical dosing headers, filter assemblies, and distribution manifolds in treatment plant piping where Schedule 80 threaded construction is specified for pressure or chemical compatibility
• Irrigation & Agriculture — Branch connections in pressurized mainline irrigation systems at valve manifolds, filter station headers, and zone distribution points where a fully threaded assembly is preferred for serviceability and seasonal reconfiguration
• Commercial & Industrial Plumbing — Full-bore threaded branch connections in cold water supply, equipment feed lines, and mechanical room piping where Schedule 80 construction is specified and threaded assembly is required at equipment connections or valve bodies
• Aquaculture & Aquatics — Branch connections in recirculating system manifolds, pump discharge headers, and filter plumbing where all-threaded Schedule 80 fittings provide reliable, reconfigurable connections at key system junctions
• Pool & Spa — Threaded branch connections at commercial pool mechanical equipment pads, chemical feed headers, and pump and filter piping where Schedule 80 threaded fittings are used throughout
• HVAC & Cooling Systems — Threaded T-branch connections in chilled water and process cooling distribution circuits where PVC Schedule 80 is specified and threaded assembly is required at equipment interfaces
