Wye, Slip x Slip x Slip, PVC Schedule 80 3" x 2" (875-338)

The 875-338 is a 3" x 2" Schedule 80 PVC reducing wye with slip socket connections on all three outlets. The fitting carries a 3" solvent-weld main run while introducing a 2" reduced branch at a 45° angle — the geometry that defines a wye and sets it apart from a standard tee in both hydraulic performance and code compliance for drain, waste, and vent (DWV) applications, gravity-flow drainage systems, and pressure piping where smooth, low-turbulence flow transition at a branch junction is a design requirement.

The 2" branch size represents a practical and frequently specified step-down from a 3" main. In industrial and commercial piping systems, this pairing appears wherever a primary 3" process line, drain header, or chemical waste main needs to accept a secondary branch from a 2" lateral without committing a full-capacity 3" branch outlet to a circuit that only requires 2" flow capacity. The step-down keeps the branch appropriately sized for its function — whether that is a secondary drain circuit, a bypass loop, a cleanout lateral, or a chemical feed return line — while the 3" run maintains full main-line capacity through the fitting.

The 45° branch entry reduces turbulence and head loss at the junction, preserves directional flow momentum through the branch transition, and supports self-cleaning characteristics that a 90° tee branch cannot provide — a meaningful performance difference in industrial waste, chemical drain, and process effluent systems where solids, particulates, or viscous media are present and accumulation at branch junctions is a maintenance and blockage concern.

All three slip sockets accept standard IPS-dimension Schedule 80 PVC pipe bonded with IPS-approved PVC solvent cement. Manufactured from rigid dark gray PVC compound to ASTM D2467, the 875-338 delivers the full wall thickness and mechanical performance advantages of Schedule 80 construction: greater pressure capacity, enhanced chemical resistance across a broad range of acids, bases, and industrial solvents, and superior impact and mechanical stress tolerance compared to Schedule 40 equivalents — making it the correct specification wherever fittings face aggressive media, elevated system pressures, or demanding industrial service conditions.

Industries & Applications:

• Industrial Drain, Waste & Vent (DWV) — Core application for Schedule 80 reducing wyes; the 45° branch geometry satisfies horizontal drain line branch connection code requirements while the Schedule 80 wall thickness handles chemical drain service, aggressive industrial effluents, and mechanical conditions that disqualify Schedule 40 fittings in heavy-duty service environments
• Chemical Processing & Manufacturing — Reducing branch junctions on 3" chemical drain headers, process waste collection lines, and rinse water systems where a 2" lateral feeds a secondary drain or return circuit; PVC's broad chemical resistance handles acids, bases, salt solutions, and a wide range of industrial solvents
• Industrial Process Piping — Low-to-moderate pressure reducing branch connections on 3" process water, coolant, and utility fluid distribution systems requiring a 2" lateral takeoff with the smooth hydraulic transition and heavy-wall durability that Schedule 80 provides
• Pharmaceutical & Laboratory Facilities — Chemical waste drain and high-purity fluid distribution branch junctions where Schedule 80 PVC is specified for aggressive effluent streams, solvent waste collection, and acid drain systems requiring corrosion-resistant fittings with reliable pressure ratings
• Pulp, Paper & Food Processing — Gravity-drain and washdown system reducing branch junctions on 3" collection headers handling dilute chemicals, caustic wash water, brine, and food-safe process effluents where Schedule 80 chemical resistance and 45° wye geometry are both specification requirements
• Semiconductor & Electronics Manufacturing — Ultra-pure water and chemical waste branch junctions in process fluid distribution systems where Schedule 80 PVC is specified for aggressive high-purity and corrosive media and the reducing wye accommodates 2" branch circuits feeding off a 3" primary line
• Water & Wastewater Treatment — Chemical feed return lines, bypass branch connections, and process drain laterals on 3" treatment plant piping where Schedule 80 durability and the wye's hydraulic efficiency at the branch junction are both system design priorities
• Mining & Power Generation — Process drainage, chemical handling, and cooling water return branch junctions in harsh industrial service environments where Schedule 80 impact resistance, chemical tolerance, and pressure capacity are required for sustained heavy-duty operation
