Tee, Slip x Slip x FPT PVC Schedule 40 5" x 5" x 1-1/2" (402-485)

The 5" x 5" x 1-1/2" PVC Schedule 40 Tee (402-485) combines a 5" slip x slip inline run with a 1-1/2" female pipe thread (FPT) branch outlet — providing a single-fitting solution for systems where a small-diameter, threaded, removable branch connection must integrate directly into a 5" primary run without secondary adapters or reducer fittings at the branch point. The two 5" slip ports accept standard Schedule 40 pipe for permanent, solvent-welded inline joints, while the 1-1/2" FPT branch accommodates any standard 1-1/2" male-threaded valve, instrument, pressure gauge, sensor, or equipment connection that requires periodic removal or replacement without disturbing the solvent-welded 5" run on either side.

At a 1-1/2" FPT branch on a 5" run, the 402-485 carries the largest size differential in this segment of the 402-series mixed-connection tee lineup — a step up in differential from the 402-486 (2" branch), 402-487 (2-1/2" branch), and 402-488 (3" branch). The pronounced difference between the 5" run and the 1-1/2" branch positions this fitting squarely in low-flow service applications: pressure monitoring taps, chemical injection ports, instrument supply connections, small valve isolation points, and minimal-flow equipment inlets that must interface directly with a large-diameter 5" primary header in a single compact fitting. At this size differential, the value of integrating the branch directly into the tee body — rather than chaining a slip tee, a reducer, and a threaded adapter — is at its most tangible: fewer joints, a tighter assembly footprint, and a single pressure-rated fitting at the tap point.

As with all fittings in the 5" diameter range, the 402-485 is a specialty fitting that buyers source almost exclusively from engineering drawings, job-specific material lists, or system design documents. The combination of 5" run, 1-1/2" FPT branch, and mixed connection type is a precise engineering specification unlikely to be field-substituted without design review, and part number accuracy is the primary procurement safeguard at this level of specificity.

Manufactured from rigid PVC to Schedule 40 specifications and dimensionally compliant with ASTM D2466, the 402-485 ensures compatibility with Schedule 40 pipe and fittings at the 5" slip ends and accepts any standard 1-1/2" MPT connection at the FPT branch. NSF 61 certification confirms suitability for potable water contact across applicable uses.

Industries & Applications:

• Industrial Process Piping — pressure monitoring taps, instrument supply connections, and small valve branch takeoffs off 5" process fluid or plant utility headers where a removable 1-1/2" threaded branch is specified without disturbing the inline solvent-welded run
• Municipal & Civil Water Distribution — low-flow service branch connections off 5" distribution mains where pressure instruments, sampling ports, or small isolation valves require a removable 1-1/2" threaded interface
• Chemical Processing — chemical injection ports, sampling connections, and 1-1/2" instrument branch taps integrated directly into 5" process headers in a single fitting without secondary reducer or adapter fittings
• Water & Wastewater Treatment — instrument and low-flow service branch connections in treatment plant process piping where a 5" slip run and 1-1/2" threaded branch are called out together in the system design
• Commercial Plumbing — specialty engineered low-flow branch connections in large commercial or institutional facilities where 5" piping and a 1-1/2" threaded branch outlet are specified in the design documents
• Irrigation & Agriculture — pressure monitoring, chemical injection, and small valve branch connections off 5" primary distribution headers in engineered large-scale irrigation systems
