Tee, Slip x Slip x FPT PVC Schedule 40 5" x 5" x 1" (402-483)

The 5" x 5" x 1" PVC Schedule 40 Tee (402-483) combines a 5" slip x slip inline run with a 1" female pipe thread (FPT) branch outlet — the smallest branch configuration in the 402-series 5" mixed-connection tee lineup, purpose-built for systems where a minimal-flow, threaded, removable branch connection must tap directly into a 5" primary run in a single fitting. The two 5" slip ports accept standard Schedule 40 pipe for permanent, solvent-welded inline joints, while the 1" FPT branch accommodates any standard 1" male-threaded valve, pressure gauge, instrument, sensor, or service connection that requires periodic removal or replacement without cutting into or disturbing the solvent-welded 5" run on either side.

The 1" FPT branch on a 5" run represents the most extreme size differential in this segment of the 402-series lineup — a full four nominal pipe sizes between the run and the branch. At this differential, the fitting is purpose-designed for the most specialized low-flow service applications: pressure gauge connections, chemical injection quills, instrument air or fluid supply taps, vent connections, sample ports, and minimal-flow equipment inlets that must integrate directly with a large-diameter 5" primary header at a single, permanent, pressure-rated tap point. The alternative — a slip tee, a reducer bushing, and a threaded adapter assembled in sequence at the branch — introduces three fittings and three additional joints where the 402-483 delivers one. In systems where branch tap count is high or installation space is constrained, this consolidation has meaningful practical value.

As with every fitting in the 5" diameter range, the 402-483 is a specialty SKU sourced almost exclusively from engineering drawings, P&ID documents, or job-specific material lists. A 5" run with a 1" FPT branch is a configuration that does not arise from general plumbing practice — it reflects a deliberate, engineered design decision, and buyers sourcing this fitting are working to a precise specification where part number accuracy is the primary procurement control.

Manufactured from rigid PVC to Schedule 40 specifications and dimensionally compliant with ASTM D2466, the 402-483 ensures compatibility with Schedule 40 pipe and fittings at the 5" slip ends and accepts any standard 1" MPT connection at the FPT branch. NSF 61 certification confirms suitability for potable water contact across applicable uses.

Industries & Applications:

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