Reducing Tee, Slip x Slip x Slip 10" x 10" x 8" (C601-628)

The 10" x 10" x 8" PVC Reducing Tee (C601-628) is a Class 125, slip-socket fitting designed for large-diameter pipeline systems where the branch demand is nearly equal to the main — delivering an 8" outlet directly off a 10" run in a single, solvent-welded fitting assembly. With slip connections on all three ports, the C601-628 forms a permanent, full-pressure joint across the entire fitting body, eliminating the additional joints, flow restrictions, and installation complexity that come with pairing a standard full-size tee with a separate inline reducer.

The relatively small reduction ratio between the 10" run and the 8" branch makes this a hydraulically demanding junction — one where fitting quality, wall integrity, and joint execution are especially critical. Manufactured from virgin PVC compound meeting ASTM D2466 dimensional standards, the C601-628 provides the structural consistency and material uniformity necessary to maintain rated pressure performance at this near-full-bore branch configuration.

The Class 125 pressure rating aligns with the operating conditions of the transmission mains, primary distribution headers, and high-volume process lines where 10" PVC pipe is most commonly specified. For system designers, the availability of a single reducing tee at this size combination simplifies hydraulic modeling, reduces installed fitting count, and supports cleaner as-built documentation compared to multi-fitting branch assemblies.

Specifications:

Heavy-bodied solvent cement is strongly recommended for all socket joints at 8" and above. Allow full extended cure time before pressurizing — large-diameter socket joints require significantly longer cure schedules than small-bore fittings. Pressure-temperature derating applies at elevated service temperatures per ASTM standards.

Industries & Applications:

• Municipal Water Distribution — Transmission and primary distribution mains requiring a near-full-bore 8" branch feed to parallel distribution loops, storage fill lines, booster station inlets, or major service zone headers
• Agricultural & Large-Scale Irrigation — 10" mainline trunk systems with 8" branch drops to high-capacity sub-main headers, large pump station inlets, or multi-zone valve manifolds on large farms, golf courses, and managed landscapes
• Industrial Process Piping — High-volume fluid handling systems where a near-equal branch split feeds a secondary process loop, parallel cooling circuit, or large-capacity distribution header
• Water & Wastewater Treatment — Plant distribution mains supplying 8" branch feeds to filtration trains, aeration basins, clarifier inlet headers, or secondary treatment process lines
• Stormwater & Flood Control Infrastructure — Large-diameter gravity or low-pressure collection systems requiring a high-volume 8" branch junction off a 10" trunk main
• Fire Protection & Suppression Supply — Underground supply mains with 8" branch feeds to large-diameter fire hydrant laterals, dedicated fire storage fill lines, or high-demand suppression system risers
• Power Generation & Industrial Cooling — Cooling water distribution mains requiring a near-full-bore branch split to parallel cooling towers, large heat exchanger banks, or process cooling skids
• Aquaculture & Water Management — High-flow recirculation or intake headers requiring a large-volume branch split to parallel raceways, pond inlet manifolds, or treatment system bypass loops
