Tee, Slip x Slip x Slip PVC Schedule 80 1-1/4" x 1/2" (801-166)

The 801-166 is a 1-1/4" x 1/2" PVC Schedule 80 reducing tee in a slip x slip x slip configuration, featuring 1-1/4" slip inlets on both run ends and a reduced 1/2" slip branch outlet. This fitting allows a branch takeoff at a smaller diameter to be introduced directly into a 1-1/4" mainline run — all in a single solvent-weld fitting without additional adapters or reducers.

The slip x slip x slip configuration means all three ports accept solvent cement connections, making installation clean, permanent, and consistent with standard Schedule 80 PVC assembly practice. The 1-1/4" run ports maintain full mainline flow continuity, while the 1/2" branch handles the reduced-diameter takeoff for instrument taps, sampling ports, chemical injection points, secondary supply lines, or smaller distribution laterals.

Schedule 80's thicker wall construction — compared to Schedule 40 — provides higher pressure ratings and greater resistance to mechanical stress, chemical exposure, and harsh operating conditions. The gray color is the universal identifier for Schedule 80 PVC, providing a clear visual distinction in systems where white Schedule 40 components are also present.

Solvent cement installation follows standard PVC practice: clean, prime, and cement all mating surfaces per ASTM D2564 procedures. Ensure proper alignment before the cement sets, as Schedule 80 socket fits leave minimal adjustment time once bonded.

Industries & Applications:

The 801-166 reducing tee is well-suited for any Schedule 80 system requiring a smaller branch takeoff from a 1-1/4" mainline run:

• Industrial Processing — Branch connections for chemical injection, sampling lines, or instrument taps off a 1-1/4" process header, with the 1/2" port handling the reduced-flow secondary function
• Chemical Handling — Introducing smaller-diameter feed or bleed lines into a mainline distribution system in acid, alkali, or reagent piping
• Water & Wastewater Treatment — Branching off 1-1/4" supply or distribution headers to 1/2" metering, dosing, or monitoring connections at treatment equipment
• Irrigation & Agriculture — Tapping a 1/2" lateral or drip supply line off a 1-1/4" mainline in pressurized field or greenhouse irrigation systems
• Commercial & Industrial Plumbing — Creating reduced-size branch connections in cold water supply, equipment feed lines, and mechanical room piping
• Aquaculture & Aquatics — Branching recirculating system manifolds to smaller-diameter filter, aeration, or monitoring connections
• Laboratory & Research Facilities — Integrating sampling ports or reagent feed lines into 1-1/4" Schedule 80 laboratory piping systems
