The NDS 4P11 is a molded PVC hub x FPT cleanout adapter that provides a reliable access point for 4 in sewer and drainage systems. The solvent-weld hub end connects to 4 in S&D pipe while the 4 in female pipe thread (FPT) accepts a 4 in male pipe-thread (MPT) cleanout plug (model 41P8), sold separately. Designed for non-pressurized underground use, the adapter meets applicable ASTM standards and is molded from Type I PVC for long-term durability.

  • Hub x FPT connection — solvent-weld hub fits 4 in S&D pipe; FPT accepts 4 in MPT cleanout plug (41P8), sold separately.
  • Material: Type I PVC with UV inhibitors; molded in the USA. Compatible with SDR-35, SDR-26, triple wall and ASTM D-2729 pipe.
  • Dimensions & weight: approximately 2.77 in length; around 0.3 lb for easy handling and installation.
  • Standards & rating: meets applicable ASTM specifications; intended for non-pressurized underground sewer and drainage applications with a maximum working pressure of 5 psi.
  • Purpose: creates a threaded cleanout or access point to clear clogs and perform routine maintenance without disturbing the main line.

Installation uses standard PVC solvent-weld procedures to form a permanent joint. For a threaded cleanout, pair the adapter with a 4 in MPT cleanout plug. Consult the NDS product technical sheet and drainage catalog for detailed specifications, installation diagrams, and application guidance. If your project requires pressure-rated components or specialized chemical resistance, review product documentation or consult a qualified engineer.
