Reducing Tee, Slip x Slip x FPT PVC Schedule 40 4" x 4" x 2" (402-420)

The 402-420 is a PVC Schedule 40 reducing tee with a 4" slip (socket) run and a 2" 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 2" FPT branch provides a threaded takeoff point compatible with any standard 2" NPT male-threaded fitting, valve, pump connection, or equipment port — 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 402-420 occupies a distinct and practical position within the 4" x 4" FPT reducing tee series — the 2" branch is large enough to support meaningful branch flow volumes for bypass circuits, zone supply lines, and mid-size valve connections, yet represents a significant enough reduction from the 4" mainline to function as a controlled branch rather than a near-equal split. This makes the 402-420 well suited for systems where the 4" mainline must remain the primary flow path while a 2" branch handles a secondary circuit, parallel loop, or high-flow service connection. As with all FPT branch configurations, the threaded outlet remains serviceable — valves, strainers, and inline equipment at the branch can be removed and replaced without cutting or disturbing the permanent solvent-welded mainline, a practical advantage in systems where branch components require periodic maintenance or future reconfiguration.

Industries & Applications:

• Irrigation & Agriculture — Mid-flow branch takeoffs off 4" mainline headers for 2" zone valves, bypass assemblies, and secondary lateral supply lines in large-scale pressurized irrigation systems where the branch must carry moderate flow volumes
• Municipal Water & Wastewater — Secondary service branches and bypass connections off 4" distribution mains at pump stations and treatment facilities where a 2" threaded branch accommodates valves, meters, or parallel circuit feeds
• Industrial Process Piping — Mid-diameter threaded branch taps off 4" process fluid and cooling water mainlines for bypass loops, flow control valves, strainer assemblies, and secondary service connections requiring a serviceable threaded joint
• Commercial Plumbing — Mechanical room distribution headers where a 4" supply main requires a 2" threaded branch for secondary service circuits, equipment connections, or bypass assemblies
• Fire Suppression — Branch connections off 4" sprinkler system mains where a 2" threaded takeoff accommodates inspector test connections, drain valves, or secondary branch mains
• Aquaculture & Water Treatment — Mid-volume branch taps off large-diameter supply headers in recirculating aquaculture and water treatment systems where the branch circuit must support secondary flow capacity without reducing mainline throughput
