Compact Schedule 40 PVC reducing adapter designed to join a 3/4" solvent-weld (slip) pipe to a 1" female pipe thread (FPT). Manufactured from durable white PVC, this reducer is engineered for irrigation, landscape and general plumbing applications where a reliable transition between slip and threaded connections is required.

  • Material: Rigid PVC (Schedule 40) for corrosion resistance and long service life.
  • Connections: 3/4" slip (solvent-weld) to 1" female pipe thread (FPT/FNPT) — use approved solvent cement on the slip end and appropriate thread sealant on threaded end.
  • Temperature & Standards: Rated to 140°F; meets ASTM D2466 and commonly supplied to NSF 14 and NSF 61 standards for potable water/irrigation fittings.
  • Applications: Ideal for irrigation, landscape irrigation systems, drainage, and other cold-water plumbing where PVC Schedule 40 fittings are suitable. Not for compressed air or gases.
  • Sizes & Fit: Reducing adapter for 3/4" nominal slip pipe to 1" nominal female thread; verify pipe schedule and thread compatibility before installation.

This adapter is a straightforward, cost-effective solution when converting from solvent-weld PVC piping to threaded components. For secure performance, clean and dry surfaces before solvent welding, allow proper cure time for the cement, and apply a compatible thread sealant to the FPT connection. Consult local plumbing codes for permitted uses and pressure ratings in your installation.
