Reducing Tee, Slip x Slip x Slip PVC Schedule 40 5" x 5" x 2" (401-486)

The 5" x 5" x 2" PVC Schedule 40 Reducing Tee (Part No. 401-486) is a large-diameter, white-body fitting designed to introduce a 2" branch connection off a 5" Schedule 40 PVC main line. The two run ports maintain the full 5" bore for straight-through flow continuity, while the branch port steps down to 2" — all three ports accepting solvent-cement joints in a slip (socket) configuration, producing a rigid, leak-resistant assembly suited to the high-volume flow applications where large-diameter Schedule 40 PVC is the specified material.

The three-step branch reduction from 5" to 2" is the defining characteristic of this tee and the feature that most clearly positions it within the 5" reducing tee series. Where the adjacent 401-488 (5" × 3" branch) and 401-490 (5" × 4" branch) serve branch circuits requiring substantial to near-full-run flow capacity, the 401-486 is the appropriate specification where the branch circuit serves a distinctly secondary function relative to the main run — a 2" branch off a 5" main represents a deliberate and significant flow partition, directing the majority of system flow through the 5" run while supplying a well-defined, moderate-capacity 2" branch at the junction.

This size combination appears most frequently at system points where a 5" main must deliver a service connection, equipment supply, zone entry feed, or secondary distribution circuit at 2" without interrupting or reducing the primary 5" flow path through the fitting. In large-scale municipal, irrigation, and industrial systems, the 2" branch at this junction commonly serves pump bypass connections, chemical feed inlets, metering station supply lines, pressure zone entries, and equipment interfaces where 2" is the standard port size for the connected component.

The three-size step-down also makes this tee a practical alternative to pairing a same-size 5" tee with a downstream 5" × 2" reducer or multi-bushing stack on the branch outlet. Consolidating the branch connection and the full reduction into a single fitting eliminates multiple downstream fittings and solvent-cement joints, shortens the branch outlet assembly, and simplifies installation at a junction point where each fitting and joint represents a meaningful cost and labor consideration at large diameter.

As with all 5" Schedule 40 fittings, buyers sourcing the 401-486 are working from a confirmed project specification — the 5" × 2" size combination is specific enough that it is almost never an incidental purchase, and the availability of this exact reducing configuration in a single white Schedule 40 PVC fitting is frequently the critical item in the project procurement list.

Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2466 dimensional standards and is compatible with Schedule 40 PVC pipe and solvent cements meeting ASTM D2564.

Industries & Applications:

• Municipal Water Distribution — Service connections, metering station supply lines, and pressure zone entry feeds branching at 2" off 5" transmission or distribution mains where the primary flow path must be maintained at full 5" capacity through the run
• Large-Scale Irrigation — Equipment supply connections, pump bypass feeds, and secondary zone entries tapped at 2" off 5" agricultural and landscape irrigation mains where the branch serves a defined secondary function relative to the primary distribution run
• Industrial Process Water — Secondary circuit feeds, equipment supply connections, and bypass lines branching at 2" off 5" process water or cooling water mains where the branch serves a moderate-capacity secondary function without reducing the primary run diameter
• Stormwater & Site Drainage — Secondary branch outlets on large-diameter stormwater conveyance systems where a 2" overflow, bypass, or monitoring connection must be introduced off a 5" main collection or discharge run
• Water & Wastewater Treatment — Chemical feed inlets, recirculation circuit connections, and secondary process supply branches introduced at 2" off 5" PVC plant distribution or collection mains without interrupting the primary flow path
• Commercial & Institutional Construction — Service connection branches and secondary system feeds on 5" PVC utility mains where a 2" branch serves building service entries, equipment supply points, or system monitoring connections
• Retrofit & System Expansion — Branch junction fittings on existing 5" Schedule 40 PVC infrastructure where a new 2" service connection, bypass, or secondary circuit must be introduced at a system branch point without modifying or upsizing the existing main line
