Reducing Tee, Slip x Slip x Slip PVC Schedule 40 4" x 4" x 3/4" (401-416)
The 401-416 is a PVC Schedule 40 reducing tee with a 4" slip (socket) run and a 3/4" slip (socket) branch outlet, all joined by solvent cement welding per ASTM D2564. The two 4" run ports accept standard 4" PVC pipe ends for a permanent, pressure-rated inline connection, while the 3/4" slip branch accepts a standard 3/4" PVC pipe end — creating a fully solvent-welded, three-way reducing junction with no threaded connections at any port.
Manufactured from rigid PVC compound conforming to ASTM D1784 cell classification requirements, this fitting delivers the corrosion resistance, chemical compatibility, and long service life associated with Schedule 40 PVC across a wide range of commercial, industrial, and municipal piping systems. The Schedule 40 wall thickness provides reliable pressure-rated performance for both pressurized distribution systems and gravity-flow applications.
The 401-416 is the all-slip counterpart to the 402-416 (4" x 4" x 3/4" FPT branch) and the distinction between them is both fundamental and consequential: where the 402-416 provides a threaded branch that remains serviceable throughout the system's life, the 401-416 produces a permanent solvent-welded branch joint that cannot be disconnected without cutting pipe. This makes the 401-416 the correct choice when the 3/4" branch connection is a fixed, long-term installation — a permanent chemical injection point, a dedicated air vent line, a condensate discharge tap, or a low-volume service branch that will never require removal, replacement, or reconfiguration. For any application where the downstream branch component — a valve, gauge, instrument, or inline device — may need to be removed or serviced in the future, the 402-416 with its threaded FPT branch is the more appropriate selection. The 3/4" branch size carries the same application context as its FPT counterpart: large enough to accommodate a range of low-to-moderate flow service connections and dedicated branch lines, yet small enough relative to the 4" mainline to function as a controlled tap that preserves mainline flow capacity unimpeded. The all-slip configuration produces three permanent solvent-welded joints across all ports, delivering a clean, fully bonded installation with no thread engagement or sealant requirements at any connection point.

Industries & Applications:
- Irrigation & Agriculture — Permanent 3/4" branch taps off 4" mainline headers for fixed chemical injection lines, air vent connections, and dedicated low-flow service branches in large-scale pressurized irrigation systems where the branch is a permanent installation with no future serviceability requirement
- Municipal Water & Wastewater — Permanent sample taps, chemical dosing injection points, and fixed low-flow service branches off 4" distribution mains at pump stations and treatment facilities where an all-solvent-weld branch connection is specified for long-term reliability
- Industrial Process Piping — Permanent 3/4" branch taps off 4" process fluid and cooling water mainlines for fixed chemical injection ports, air venting, pressure relief discharge, and permanent low-volume sampling connections in fully solvent-welded piping systems
- HVAC & Mechanical — Permanent condensate drain taps, air vent connections, and fixed low-flow service branches off 4" chilled water and condenser water mainlines in commercial mechanical rooms where all-slip construction is specified throughout the system
- Commercial Plumbing — Permanent minimal-flow branch connections off 4" distribution headers for fixed equipment drain taps, overflow discharge lines, and dedicated low-volume utility connections where the branch will not require future removal or adjustment
- Fire Suppression — Permanent pressure gauge taps, inspector test connection feeds, and fixed instrument branches off 4" sprinkler system mains where an all-solvent-welded 3/4" branch is specified as part of a fully bonded system installation
