The NDS 3C06 3" HDPE Corrugated End Cap seals the end of 3" single-wall corrugated pipe and the 3" slotted pipe used in the EZflow® Gravel-Free French Drain System. Engineered for non-pressurized underground drainage, this end cap stops flow at the pipe terminus and provides a secure, long-lasting closure for French drains, landscape drainage, and subsurface conveyance applications.

  • Durable HDPE construction with UV stabilizers for long service life in buried applications.
  • Internal locking tabs hold the pipe securely in place—simple insertion until tabs engage.
  • Meets applicable ASTM standards and is rated for non-pressurized drainage (maximum working pressure 5 psi).
  • Designed specifically for 3" single-wall corrugated and EZflow slotted pipe connections.
  • Black finish for UV and soil compatibility; made in the USA.
  • Low-profile end cap resists sediment intrusion and closes open pipe ends cleanly.

Easy to store and install, the 3C06 is a straightforward solution for contractors and DIYers managing small-diameter drainage runs. Use with matching corrugated or EZflow components to complete your drainage system; consult NDS technical literature or the product catalog for installation drawings and full specifications.
