Reducing Tee, Slip x Slip x FPT PVC Schedule 40 4" x 4" x 3/4" (402-416)
$23.35
The 402-416 is a PVC Schedule 40 reducing tee with a 4" slip (socket) run and a 3/4" female pipe thread (FPT) branch outlet. The two 4" run ports accept solvent cement welding per ASTM D2564 for a permanent, pressure-rated inline connection, while the 3/4" FPT branch provides a threaded takeoff point compatible with any standard 3/4" NPT male-threaded fitting, valve, gauge, or instrument — no solvent welding required at the branch.
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 combination of a large-diameter solvent weld run and a small-diameter threaded branch is a practical and widely used configuration in mainline distribution systems where a 4" header must be tapped for instrumentation, chemical injection, pressure monitoring, zone valves, or small-diameter service connections — without stepping down the mainline diameter. The 3/4" FPT branch is well suited for this role: large enough to accommodate a broad range of valves, gauges, and service fittings, while small enough to function as a controlled tap rather than a primary flow branch. PTFE thread tape or appropriate thread sealant should be applied to the male threads before assembly to ensure a leak-resistant seal at the branch port. The threaded branch remains serviceable — valves, gauges, and instruments can be removed and replaced without disturbing the upstream solvent-welded mainline.
