402-166 is a Schedule 40 PVC combination reducing tee designed to branch a 1/2" threaded outlet from a 1-1/4" PVC run. Made for irrigation, sprinkler, and general plumbing use, this fitting pairs two solvent-weld slip sockets with a 1/2" female pipe thread so you can combine glued PVC piping with threaded accessories. Built from durable white PVC, the part meets common industry standards and installs with standard PVC solvent cement and thread sealant.

  • Nominal size: 1-1/4" x 1-1/4" x 1/2" — fits 1.25" pipe run with a 1/2" threaded branch.
  • Connection type: Slip x Slip x FIPT (female iron pipe thread) for solvent-weld main run and threaded accessories.
  • Material and schedule: SCH 40 PVC in white — durable and corrosion-resistant for outdoor and underground applications.
  • Standards: Listed with common industry specifications; manufacturer listings reference NSF/ANSI 14 and NSF/ANSI 61 for typical potable and irrigation use.
  • Performance: Typical temperature rating up to 140°F and working pressure consistent with SCH 40 PVC fittings for these nominal sizes.
  • Packaging and SKUs: Sold as individual pieces (SKU 402166) and in case packs (SKU 402166-25) for contractors and bulk buyers.

Use PVC solvent cement on the slip ends and PTFE tape or approved pipe thread sealant on the 1/2" FIPT outlet for a reliable, watertight connection. This reducing tee is a practical choice when you need to add a threaded riser, valve, or accessory to a 1-1/4" PVC line while maintaining a solvent-weld run. Verify local code for potable applications and follow manufacturer instructions for pressure and temperature limits.
