Reducing Tee, Slip x Slip x Slip PVC Schedule 80 8" x 8" x 3" (801-580)
The 8" x 8" x 3" PVC Schedule 80 Reducing Tee (Slip x Slip x Slip), Part #801-580, is a heavy-wall, large-diameter branch fitting engineered for demanding piping systems where a 3-inch branch takeoff is required from an 8-inch mainline run. Manufactured from Type I, Grade I PVC compound to ASTM D2467 specifications, Schedule 80's thicker wall construction delivers higher pressure ratings, greater impact resistance, and superior long-term durability compared to Schedule 40 equivalents — making it the preferred specification for industrial process, chemical handling, and high-cycle pressure applications.
The slip x slip x slip (plain end) configuration accepts solvent cement across all three ports, producing a permanent, chemically bonded joint at the run and branch connections. The pronounced size differential between the 8-inch run and the 3-inch branch makes this fitting well suited for systems where a high-volume mainline must supply a significantly smaller branch circuit — common in chemical distribution headers, industrial cooling loops, municipal water infrastructure, and large-scale irrigation manifolds where zone feeds or instrumentation takeoffs branch off a primary trunk.
Unlike bushed or fabricated alternatives, a purpose-manufactured reducing tee at this size maintains consistent wall integrity at the tee body and branch junction, reducing stress concentration and the risk of joint failure under sustained or cyclic pressure loads. For buried, chemical-exposure, or continuous-service installations, Schedule 80's added wall thickness provides meaningful safety margin over Schedule 40 in the same size range.
Specifications:
| Specification | Details |
|---|---|
| Part Number | 801-580 |
| Fitting Type | Reducing Tee |
| Connection Type | Slip x Slip x Slip (Plain End / Solvent Weld) |
| Run Size | 8 inches x 8 inches |
| Branch Size | 3 inches |
| Material | PVC (Polyvinyl Chloride) — Type I, Grade I |
| Schedule | Schedule 80 |
| Color | Gray |
| Pressure Rating | ~160 PSI @ 73°F (run); branch rating may vary — see derating tables |

Note: Pressure ratings decrease with elevated temperatures and at the branch junction under dynamic flow conditions. Consult engineering specifications and ASTM derating curves for operating conditions above 73°F or where water hammer or surge pressure is a design factor.
Industries & Applications:
- Industrial Process Piping — Branch takeoffs from primary chemical distribution headers, plant utility mains, and process water loops where Schedule 80's heavier wall is required by engineering spec or facility standards.
- Chemical Handling & Water Treatment — Systems conveying acids, caustics, chlorinated water, or other aggressive media where PVC's broad chemical resistance and Schedule 80's added wall thickness are both critical selection criteria.
- Municipal Water Infrastructure — High-pressure water distribution systems requiring a branch tap off an 8-inch main with a 3-inch service or instrument feed.
- Irrigation & Agricultural Systems — Large-scale mainline manifolds where a 3-inch zone or sector feed branches off an 8-inch supply header, particularly in systems requiring higher pressure ratings than Schedule 40 can support.
- HVAC & Mechanical Systems — Chilled water, condenser water, and cooling tower loop branch connections in large commercial or industrial facilities where system pressure or flow dynamics demand Schedule 80 specification.
- Power Generation & Utilities — Cooling water, service water, and chemical feed systems in power plants, refineries, and heavy industrial facilities.
- Aquaculture & Fish Hatcheries — High-flow recirculating aquaculture systems (RAS) where large-diameter mainlines branch to smaller tank supply or filtration feeds.
- Mining & Aggregate Processing — Process water and slurry system branch connections where corrosion resistance and wall integrity under intermittent pressure are essential.
