Make precise turns in 4" sewer and drain (S&D) or triple-wall pipe runs with the NDS Swivel-Fit Variable-Angle Fitting. This adjustable 4" Hub x Hub PVC fitting rotates and locks at any angle between 0° and 90°, eliminating the need for multiple fixed-angle elbows and speeding up installation on-site. Designed for non-pressurized underground drainage systems, the 4PVAF is compatible with channel drain outlets, Flo-Well® Dry Well systems, drainage grates, and pop-up emitters.

  • Adjustable 0°–90° swivel: Rotate to the exact turn angle you need and lock in place for a secure joint.
  • PVC construction: Durable polyvinyl chloride body for reliable, long-term drainage performance.
  • Hub x Hub solvent-weld connection: Creates a permanent join to 4" S&D or triple-wall pipe.
  • Meets ASTM standards: Engineered for non-pressurized drainage applications; not approved for septic systems.
  • Low-pressure rating: Maximum working pressure of 5 psi — intended for gravity drainage systems.

The Swivel-Fit design simplifies inventory and reduces project cost by replacing multiple fixed-angle fittings. Installers appreciate the controlled pivot and locking ring for accurate alignment without re-cutting or complicated assemblies. Refer to the NDS drainage catalog for specification sheets and installation guidance.
