The Lasco 402-417 combination reducing tee is a Schedule 40 PVC fitting designed to join two 4‑inch slip branches to a 1‑inch female‑threaded outlet. Built for pool, spa, irrigation and general plumbing use, it offers durable, corrosion‑resistant performance for wet and outdoor environments.

  • Schedule 40 PVC construction: Injection‑molded material provides consistent dimensions and long‑term resistance to corrosion and common chemicals encountered in pool, spa and irrigation systems.
  • Nominal size: 4" x 4" x 1" — two 4" slip/socket inlets with a 1" FPT (female pipe thread) reducing outlet for a reliable size transition.
  • Connections: Slip x Slip x FPT (socket x socket x female pipe thread). Use PVC primer and solvent cement for slip joints; seal threaded outlet with PTFE tape or approved pipe‑thread compound.
  • Typical applications: Pool and spa plumbing, irrigation lines, drainage and commercial or residential water distribution where Schedule 40 fittings are specified.
  • Installation benefits: Standard Schedule 40 IPS dimensions ensure easy fit with compatible PVC pipe; lightweight design simplifies handling and reduces installation time.

Ideal for contractors and knowledgeable DIY installers, the 402‑417 reducing tee gives a dependable, industry‑standard solution for redirecting and reducing flow between 4" and 1" PVC lines.
