Reducing Tee, Slip x Slip x Slip 1/2" x 3/8" (9801-073)

The 9801-073 is a PVC reducing tee with 1/2-inch slip (socket) connections on both run ends and a 3/8-inch slip (socket) outlet on the branch. All three ports accept PVC pipe via solvent cement — the 1/2" run sockets accept standard 1/2" PVC pipe, while the 3/8" branch socket accepts standard 3/8" PVC pipe — producing a fully cemented, permanent inline branch connection with a smaller-bore branch outlet in a single compact fitting. The reduced branch configuration allows the 1/2" main run to continue uninterrupted while feeding a smaller 3/8" branch line without requiring a separate downstream reducing bushing or coupling at the branch outlet.

At these small diameters, this reducing tee is most commonly encountered in compact plumbing assemblies, appliance supply connections, laboratory distribution lines, and light-duty process systems where 3/8" branch piping is the specified downstream configuration and a fully cemented branch connection is preferred over a threaded or push-fit interface. The all-slip configuration produces permanent, bonded joints at all three ports — appropriate for installations where the branch connection is fixed and long-term joint integrity in a compact assembly is the priority.

Apply a PVC primer and solvent cement appropriate for the pipe schedule and diameter to all three socket ports and corresponding pipe ends before assembly. At these small bore sizes, work quickly after applying cement — small-diameter joints set faster than larger ones, and maintaining correct alignment through the cure set period is important for joint integrity at all three connection points.

Industries & Applications:

• Residential & Light Commercial Plumbing — Adds a 3/8" cemented branch connection to a 1/2" supply line for appliance feeds, fixture supply branches, or small-bore service connections in residential and light commercial plumbing systems where compact solvent-cemented assemblies are specified.
• Laboratory & Analytical Systems — Used in small-bore PVC distribution lines for reagent supply, DI water branches, and analytical equipment feeds where a compact all-cemented reducing tee provides a permanent branch point in confined instrument rack or bench plumbing assemblies.
• Water Treatment & Filtration — Provides a 3/8" branch tap on a 1/2" distribution or filtration system line for low-flow secondary feeds, sample ports, or chemical dosing connections in compact PVC treatment system assemblies.
• Light Industrial Process Piping — Adapts a 1/2" cemented PVC process line to a 3/8" branch connection for secondary circuits, bypass bleed lines, or small-bore instrumentation feeds in corrosion-resistant systems where an all-cemented branch assembly is specified.
• HVAC & Mechanical Systems — Connects a 3/8" condensate branch, drain line, or secondary feed to a 1/2" PVC drainage or secondary piping run in mechanical system installations where small-bore solvent-cemented fittings are used for compact equipment connections.
• Pool & Spa Chemical Systems — Used in chemical dosing and auxiliary feed assemblies where a 1/2" PVC distribution line must supply a 3/8" branch for low-flow chemical injection, sensor supply lines, or small-bore equipment connections in compact equipment room plumbing.
