The LASCO 435-012 female adapter is a reliable PVC Schedule 40 fitting that converts a solvent-weld slip connection to a female pipe thread (FPT). Designed for irrigation, landscape, and general plumbing systems, it fits 1-1/4in nominal pipe and provides consistent, leak-resistant performance for routine pressure applications.

  • Durable PVC construction: Made from rigid Type 1 PVC (Schedule 40) for long service life and excellent chemical and corrosion resistance in potable and irrigation systems.
  • Schedule 40 performance: Engineered for standard pressure applications with a typical pressure rating around 370 psi at ambient temperatures; follow manufacturer specs for temperature derating.
  • Slip x FPT connections: Slip/socket end is solvent-welded with PVC cement; apply PTFE tape or thread sealant to female pipe threads for a secure, leak-free joint.
  • Standards and listings: Manufactured to common ASTM PVC fitting specifications and listed for potable water applications where applicable.
  • Contractor-friendly design: Socket depth and consistent thread engagement simplify installation and repair for both professionals and DIY installers.

Use the 435-012 adapter for new installations or repairs where you need to transition from a solvent-weld pipe to a threaded fitting. Do not use LASCO PVC fittings for compressed air or gases and observe maximum service temperatures and installation instructions from the manufacturer to ensure safe, long-term performance.
