Reducing Tee, Slip x Slip x Slip 1" x 1" x 1/2" (9801-130)

The 9801-130 is a PVC Schedule 80 reducing tee with a 1" slip (socket) run and a 1/2" slip (socket) branch outlet, all joined by solvent cement welding per ASTM D2564. The two 1" run ports accept standard 1" PVC pipe ends for a permanent, pressure-rated inline connection, while the 1/2" slip branch accepts a standard 1/2" PVC pipe end — creating a fully solvent-welded, three-way reducing junction with no threaded connections at any port.

Manufactured from rigid, dark gray PVC compound conforming to ASTM D1784 cell classification requirements, the Schedule 80 wall construction delivers higher pressure ratings and greater mechanical strength than Schedule 40 equivalents at the same pipe size. This makes the 9801-130 the correct choice for high-pressure chemical lines, industrial process piping, and any Schedule 80 system where a permanent three-way reducing junction must maintain full Schedule 80 pressure integrity at every port without substituting lighter-wall fittings at the tap point.

The 9801-130 performs a one-half-inch reduction from the 1" run to the 1/2" branch — a substantial step-down relative to the mainline diameter that places the branch firmly in the minimal-flow tap category. At 1/2", the branch is the smallest standard pipe size in common use, accommodating individual condensate drain taps, pressure relief discharge lines, air vent connections, chemical injection points, instrument ports, and other low-volume permanent branch requirements where the 1" mainline must be tapped at the smallest useful standard size. The all-slip configuration produces three permanent solvent-welded joints across all ports — the defining characteristic that governs the application context of this fitting entirely. The 9801-130 is the correct choice when the 1/2" branch is a designed-in, fixed system element that will never require disconnection, removal, or reconfiguration at the branch joint. At a 1/2" branch in a Schedule 80 system, the downstream connected elements are typically small condensate fittings, relief valve discharge lines, or instrument connections — components that are compact and inexpensive enough that the permanent all-slip configuration is a natural fit for most installations. Buyers who anticipate any future need to service or remove the 1/2" branch connection should consider a Schedule 80 tee with an FPT branch outlet instead, which provides an identical 1" slip run with a threaded 1/2" outlet that remains fully serviceable throughout the system's life.

Industries & Applications:

• Industrial Process Piping — Permanent 1/2" minimal-flow taps off 1" Schedule 80 mainlines for fixed chemical injection points, dedicated instrument connections, condensate drain taps, and permanent low-volume service branches in high-pressure chemical distribution and process fluid systems
• Chemical Processing — Permanent minimal-flow branch taps in corrosive service piping handling acids, caustics, and aggressive fluids where all-PVC Schedule 80 construction provides both chemical resistance and pressure safety margin, and the 1/2" branch serves a dedicated injection, sampling, or discharge function
• Municipal Water & Wastewater — Permanent low-volume service branches, fixed instrument taps, and minimal-flow discharge connections off 1" Schedule 80 distribution piping at pump stations and treatment facilities where a 1/2" all-solvent-weld branch is a designed-in permanent system element
• Irrigation & Agriculture — Permanent 1/2" branch connections off 1" Schedule 80 service lines for fixed chemical injection taps, air vent connections, and dedicated low-volume service branches in high-pressure irrigation systems where Schedule 80 construction is specified for elevated pressure performance
• HVAC & Mechanical — Permanent 1/2" condensate drain taps, air vent connections, and fixed low-flow service branches off 1" Schedule 80 chilled water and condenser water service lines in commercial mechanical room installations where all-slip construction is specified throughout the system
• Aquaculture & Water Treatment — Permanent minimal-flow branch taps off 1" Schedule 80 supply and service lines for fixed chemical dosing injection points, instrument connections, and low-volume dedicated branches in recirculating aquaculture and water treatment systems
