Tee, Slip x Slip x Slip PVC Schedule 80 1/2" x 3/4" (801-074)

The 801-074 is a 3/4" × 3/4" × 1/2" PVC Schedule 80 Reducing Tee with three slip (socket) ends — a full-size 3/4" through-run and a reduced 1/2" branch outlet — all joined by solvent cement. This fitting allows a 3/4" solvent-welded Schedule 80 main line to supply a smaller 1/2" branch without introducing a threaded connection or requiring a separate full-bore tee plus reducing bushing at the branch point, consolidating the size transition and the branch takeoff into a single pressure-rated fitting.

Manufactured from dark gray PVC Schedule 80 compound and compliant with ASTM D2467, this tee carries NSF/ANSI 61 certification for potable water contact. The heavier Schedule 80 wall thickness provides the elevated pressure rating and chemical resistance required in industrial process environments, chemical handling systems, and high-demand commercial applications where Schedule 40 fittings are undersized for the service conditions or insufficiently resistant to the process media. All three socket ends accept their respective pipe sizes via standard solvent cement joints — no threaded connections, no gaskets, and no mechanical seals are involved in the assembly.

The 3/4" × 1/2" run-to-branch geometry is a practical configuration in small-bore industrial and commercial piping where a 3/4" distribution line must supply a 1/2" instrument tap, equipment inlet, auxiliary feed, or service connection without stepping down in a separate fitting. The reduced 1/2" branch keeps the branch-side velocity and pressure drop within acceptable limits for low-to-moderate flow demand applications, while the 3/4" through-run preserves main-line flow capacity across the tee body — making this fitting a compact and efficient solution for branch takeoffs where the downstream branch demand is clearly lower than the main-line flow.

Solvent cement installation follows standard Schedule 80 procedures across all three socket ends — clean, prime, and cement each mating pipe surface using a Schedule 80-compatible PVC cement per ASTM D2564. The governing pressure rating for the assembled fitting is determined by the smallest socket end — the 1/2" branch outlet; consult the manufacturer's published technical data for this specific reducing combination before specifying to a system working pressure.

Specifications

Industries & Applications

• Industrial Process Piping — Branch takeoffs on 3/4" Schedule 80 process water, cooling water, and chemical transfer lines where a 1/2" instrument tap, sample port, or auxiliary equipment feed must be introduced without stepping down in a separate fitting downstream of a full-bore tee
• Chemical Handling — Corrosion-resistant reducing branch tees in acid, alkali, and industrial reagent distribution lines where a 3/4" supply main must supply a 1/2" injection port, dosing inlet, or secondary feed point with a single solvent-welded fitting at the branch location
• Water Treatment & Purification — Branch tees on 3/4" Schedule 80 distribution lines serving 1/2" filter housing inlets, UV system ports, and chemical dosing equipment connections in municipal and industrial water treatment systems where Schedule 80 is specified for chemical resistance
• Commercial Plumbing — Reducing branch takeoffs in commercial mechanical rooms and utility systems where a 3/4" Schedule 80 supply line must serve a 1/2" fixture connection, equipment port, or auxiliary service line without a separate reducing fitting at the branch
• Instrumentation & Controls — Branch tees providing 1/2" instrument taps, gauge connections, and pressure sensor ports off 3/4" Schedule 80 process lines where solvent-welded branch integrity and chemical resistance are required at the tap point
• Irrigation & Agriculture — Reducing branch tees in high-pressure Schedule 80-rated agricultural and turf irrigation systems where a 3/4" distribution sub-main must supply a 1/2" lateral branch, zone valve inlet, or chemical injection tap
• HVAC & Mechanical Systems — Branch tees in Schedule 80 chilled water, cooling tower, and condenser water auxiliary lines where a 3/4" PVC distribution pipe must supply a 1/2" equipment connection or instrumentation port in a corrosion-resistant mechanical system
