Wye, Slip x Slip x Slip PVC Schedule 40 8" (475-080)

The 475-080 is an 8" Schedule 40 PVC full-size wye with slip socket connections on all three outlets. Unlike a standard tee, which introduces flow at a sharp 90° angle, the wye's 45° branch geometry allows fluid — and any entrained solids — to enter or exit the main run along a gradual, directionally consistent path. This hydraulic advantage makes the wye the preferred branch fitting over a tee in drain, waste, and vent (DWV) applications, gravity-flow drainage networks, and any system where reducing turbulence, minimizing head loss, and preventing solids accumulation at the branch junction are design priorities.

At 8", the hydraulic performance characteristics of the wye geometry carry particular weight. Large-diameter gravity-flow systems move significant volumes at relatively low velocities — conditions where a sharp 90° branch junction can create turbulent dead zones, promote sediment and debris accumulation, and generate back-pressure that reduces system capacity. The 45° wye entry keeps flow momentum aligned, supports self-cleaning flow characteristics, and reduces the risk of blockage at the branch point in ways that a same-size tee cannot match.

All three 8" slip sockets accept standard IPS-dimension Schedule 40 PVC pipe bonded with heavy-bodied PVC solvent cement — the recommended grade at large diameters where socket depth, cement coverage area, and assembly time are substantially greater than small-bore applications. The full-size configuration means all three outlets are equal at 8", making the 475-080 the correct choice for systems where the branch carries the same nominal flow capacity as the main run rather than a reduced lateral. Manufactured from virgin PVC compound to ASTM D2466, the 475-080 carries the white color standard for Schedule 40 fittings and is NSF/ANSI 61 listed for potable water service.

Industries & Applications:

• Industrial & Commercial DWV Systems — Primary application for large-diameter Schedule 40 wyes; the 45° branch angle meets code requirements for horizontal drain line branch connections and supports self-cleaning flow velocities in 8" gravity waste and drain systems serving industrial facilities, commercial buildings, and campus-scale infrastructure
• Municipal Wastewater & Stormwater — Full-capacity branch junctions on 8" sanitary sewer laterals, stormwater collection mains, and conveyance network branch points where smooth hydraulic transition at the junction minimizes surcharging and solids deposition
• Large-Scale Irrigation & Agriculture — Equal-capacity flow splitting on 8" irrigation distribution headers and mainline branch points where both the run and the branch carry equivalent flow volumes to zone laterals or pivot system feed lines
• Industrial Process Piping — Low-to-moderate pressure branch junctions on 8" process water, cooling water, and plant utility fluid distribution headers requiring smooth directional flow transitions and minimal turbulence at the branch point
• Water & Wastewater Treatment — Flow distribution and collection branch junctions on 8" treatment plant distribution headers, filter influent and effluent manifolds, and recirculating system piping where hydraulic efficiency at branch points supports process performance
• Aquaculture & Recirculating Systems — Equal-flow branch splitting on 8" recirculating system supply and return headers in large commercial aquaculture, hatchery, and water treatment facilities where balanced flow distribution across circuits is a system design requirement
• Mining & Power Generation — Cooling water returns, drainage headers, and process water distribution branch junctions in harsh industrial environments where large-diameter PVC's corrosion resistance and smooth-bore flow characteristics are advantageous over metal alternatives
• Pulp, Paper & Food Processing — Gravity drain and washdown system branch junctions on 8" collection headers handling dilute chemicals, brine, wash water, and food-safe process effluents where smooth-bore wye geometry supports drainage system hygiene and flow performance
