Tee, Slip x Slip x Slip PVC Schedule 80 4" x 1-1/4" (801-418)
$38.92
The 4" x 1-1/4" PVC Schedule 80 Reducing Tee (Part No. 801-418) is a pressure-rated, gray-body fitting built for installations requiring a substantial branch connection off a 4" main line. The slip x slip x slip (socket) configuration on all three ports accepts solvent-cement joints, producing a rigid, leak-resistant assembly engineered for the elevated pressures and chemically demanding environments where Schedule 80 is the specified standard.
The 1-1/4" reducing branch outlet occupies a practical middle ground in the 4" reducing tee series — larger than the 1" branch (801-417) and offering meaningful flow capacity to branch circuits such as equipment supply lines, secondary distribution headers, or process feeds where a 1" outlet would be undersized but a full same-size tee is unnecessary. This makes it a common specification in mid-scale industrial loops, commercial mechanical rooms, and irrigation systems with higher-demand lateral zones.
Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2467 dimensional standards and provides the increased wall thickness and pressure ratings that define Schedule 80 over Schedule 40. Compatible with Schedule 80 PVC pipe and solvent cements conforming to ASTM D2564.

- Commercial Plumbing — Mechanical room supply connections and zone feeds where 1-1/4" branch flow capacity is required under Schedule 80 pressure ratings
- Municipal Water & Wastewater — Branch connections to metering stations, service laterals, or ancillary infrastructure off 4" mains
- Irrigation — Higher-demand lateral zone feeds or pump supply branches tapped off a 4" irrigation main where a 1" outlet would be flow-restrictive
- Mining & Oil Field — Corrosive or high-pressure fluid handling environments requiring a robust, chemical-resistant branch fitting
- HVAC & Mechanical Systems — Chilled water, process cooling, or chemical feed branch lines supplying secondary equipment where 1-1/4" flow capacity is specified
