Durable Schedule 40 PVC reducing tee designed for potable-water and irrigation systems. This Lasco OEM combo reducer (402-289) pairs two 2-1/2" run sockets with a 1" branch, providing a reliable 90° branch connection where the main run remains larger than the outlet. Constructed to industry standards for long service life and chemical resistance in outdoor and indoor plumbing applications.

  • Material: Type I, Grade 1 PVC (Schedule 40) for corrosion resistance and low maintenance.
  • Connection: Socket x Socket x Female NPT (slip x slip x FNPT) for solvent-weld sockets and threaded branch.
  • Nominal sizes: 2-1/2" run × 1" branch, suitable for IPS/Schedule 40 pipe.
  • Pressure & temperature: Rated for typical system pressures (manufacturer listings show up to 300 psi depending on size and temperature); service temperature range up to approximately 140°F (60°C).
  • Standards: Manufactured to ASTM D1784 and ASTM D2466; commonly NSF-certified for potable water (NSF 14/61 on OEM listings).
  • Finish & color: Molded white PVC for visual match with standard PVC piping.

Use this fitting when you need a reliable reduction on a 2-1/2" run to a 1" branch. Socket ends accept PVC pipe with solvent cement; use appropriate thread sealant on the FNPT branch. Compatible with other Schedule 40 PVC components and widely used for irrigation, pool equipment plumbing, supply lines, and general-purpose plumbing where ASTM-compliant PVC fittings are required.
