Standard HDPE

Standard HDPE

Dura-Line manufactures standard High Density Polyethylene (HDPE) conduits for standard installation applications such as underground, as innerducts in existing conduits, or corrugated products to use in congested areas. HDPE is a flexible and resilient material. It provides superior resistance to natural or mechanical damage, and has excellent low temperature properties to handle cold weather.

Dura-Line's traditional HDPE Standard Conduit products for utilities are of superior-quality. While offering innovative designs to make installation faster, easier, and more productive, Dura-Line manufactures a broad range of sections.


Our most popular HDPE duct, Smoothwall is available with an optional Silicore permanently lubricated lining. The inherent properties of HDPE make gradual bends without special equipment, and provide outstanding long-term cable protection from shifting ground, rock, and root impingement. These ducts perform well in all environments, aerial, direct buried and underground. 

  • Size Range: 20 mm to 250 mm
  • Available with Silicore – permanently lubricated lining
  • Factory Pre-Installed Cable or Tape options

Smooth Out/Ribbed In

Our popular HDPE duct with a smooth outer wall and internal longitudinal ribs for a reduced coefficient of friction. These ducts perform well in all environments, aerial, direct buried and underground.


  • Manufactured from flexible HDPE, makes gradual bends without special equipment
  • Ribbed in maximized for greater pulling and jetting distances, reducing friction
  • Ribs direct airflow around the cable during jetting and helps minimize contact with the duct wall
  • Available with UV protectant for aerial/lashed placement
  • Includes SILICORE permanent lubricated lining


Corrugated conduit is made from HDPE and works well for short runs and where flexibility is a key requirement. This lightweight design provides excellent crush resistance and protects fiber cables in underground conduit.

Corrugated Characteristics:

  • Sizes Available: 50 mm, 63 mm, 75 mm, 90 mm, 100 mm, 110 mm, 120 mm, 160 mm, 180 mm and 200 mm
  • Manufactured from flexible HDPE
  • Provides a permanent pathway, simplifies future cable repairs or replacement
  • Option to have Bull-Line pull tape to be preinstalled
