Reducing Tee, Slip x Slip x FPT PVC Schedule 40 5" x 5" x 4" (402-490)
$49.51
The 5" x 5" x 4" PVC Schedule 40 Tee (402-490) combines a 5" slip x slip inline run with a 4" female pipe thread (FPT) branch outlet — the largest branch configuration in the 402-series 5" mixed-connection tee lineup, designed for systems where a large-diameter, threaded, removable branch connection must integrate directly into a 5" primary run without secondary adapters or additional fittings at the branch point. The two 5" slip ports accept standard Schedule 40 pipe for permanent, solvent-welded inline joints, while the 4" FPT branch accommodates any standard 4" male-threaded valve, equipment connection, strainer, or flanged adapter that requires periodic removal or replacement without disturbing the solvent-welded 5" run on either side.
At a 4" FPT branch on a 5" run, the size differential between the run and the branch is the smallest in the 402-series 5" lineup — only a single nominal pipe size separates the 5" run from the 4" branch outlet. This configuration is well suited to systems where the branch carries substantial flow volume approaching that of the primary run: a 4" valve isolation point, a large equipment inlet, a 4" threaded branch connection to a pump suction or discharge port, or a significant secondary distribution line that must maintain high flow capacity while remaining removable without cutting into the primary header. Where smaller FPT branches in this series serve instrumentation and low-flow service taps, the 4" FPT branch is a high-capacity, serviceable connection point on a primary distribution or process header.
The single-fitting integration remains the defining advantage over a two-fitting assembly — combining what would otherwise require a slip tee and a threaded adapter into one pressure-rated component keeps the branch point compact, reduces joint count, and eliminates a potential leak point at the adapter connection. At 4" branch diameter, the threaded interface also preserves the downstream serviceability that makes this tee type a deliberate engineering choice over a full slip tee: the 4" FPT port allows large valves, strainers, or equipment connections to be removed and replaced as maintenance requires without affecting the permanent 5" solvent-welded run.
As with all fittings in the 5" diameter range, the 402-490 is a specialty SKU sourced almost exclusively from engineering drawings, job-specific material lists, or system design documents. A 5" slip run with a 4" FPT branch is a precisely specified configuration, and part number accuracy is the primary procurement safeguard for buyers sourcing this fitting against a design document.
Manufactured from rigid PVC to Schedule 40 specifications and dimensionally compliant with ASTM D2466, the 402-490 ensures compatibility with Schedule 40 pipe and fittings at the 5" slip ends and accepts any standard 4" MPT connection at the FPT branch. NSF 61 certification confirms suitability for potable water contact across applicable uses.

Industries & Applications:
- Industrial Process Piping — large-diameter threaded valve, pump, or equipment branch connections off 5" process fluid or plant utility headers where a removable 4" branch interface is specified without disturbing the inline solvent-welded run
- Municipal & Civil Water Distribution — high-flow service branch takeoffs with threaded 4" connections off 5" distribution mains where large isolation valves, meters, or equipment require a removable branch interface at near-full-flow capacity
- Chemical Processing — large-diameter threaded equipment inlets, valve isolation points, and high-flow branch connections integrated directly into 5" process headers in a single fitting without secondary adapter fittings
- Water & Wastewater Treatment — high-capacity instrument and service branch connections in treatment plant process piping where a 5" slip run and 4" threaded branch are called out together in the system design
- Commercial Plumbing — specialty engineered high-flow branch connections in large commercial or institutional facilities where 5" piping and a near-full-size 4" threaded branch outlet are specified in the design documents
- Irrigation & Agriculture — large valve, pump, or equipment branch connections off 5" primary distribution headers in engineered large-scale irrigation systems where branch flow capacity must remain high

Reducing Tee, Slip x Slip x FPT PVC Schedule 40 5" x 5" x 4" (402-490)
The 5" x 5" x 4" PVC Schedule 40 Tee (402-490) combines a 5" slip x slip inline run with a 4" female pipe thread (FPT) branch outlet — the largest branch configuration in the 402-series 5" mixed-connection tee lineup, designed for systems where a large-diameter, threaded, removable branch connection must integrate directly into a 5" primary run without secondary adapters or additional fittings at the branch point. The two 5" slip ports accept standard Schedule 40 pipe for permanent, solvent-welded inline joints, while the 4" FPT branch accommodates any standard 4" male-threaded valve, equipment connection, strainer, or flanged adapter that requires periodic removal or replacement without disturbing the solvent-welded 5" run on either side.
