Lasco Schedule 40 PVC reducer bushing (6" x 4") provides a reliable spigot-to-slip transition for IPS plumbing systems. Injection-molded PVC resists corrosion and chemical exposure, making it suitable for pool, irrigation, and general plumbing installations.

  • Material: Schedule 40 PVC, injection-molded for dimensional accuracy.
  • Sizes: 6" (spigot) x 4" (slip) nominal IPS dimensions.
  • Connection Type: Spigot x Slip (socket x slip) — cement or solvent-weld installation.
  • Pressure & Temperature: Rated for typical Schedule 40 service; consult local codes for exact limits (commonly up to 150 PSI at 73°F and temperatures to approximately 140°F).
  • Applications: Pool/spa plumbing, irrigation mainlines, residential and commercial water systems.
  • Benefits: Corrosion resistance, lightweight handling, long service life, compatible with standard PVC fittings.

Each bushing is manufactured to industry standards for IPS Schedule 40 fittings. For solvent-weld joints, clean and prime surfaces before cementing and follow pipe/fitting manufacturer instructions for a secure seal. If you require certification, material sheets or dimensional drawings, contact us and we'll provide manufacturer documentation.
