Feature
Benefits of Microducts HDPE
✦ SPECIFICATIONS/DETAILS MicroDucts are smaller diameter conduit, manufactured from flexible HDPE.
✦ FILL RATIO Choose the correct MicroDuct size based on the Outer Diameter (OD) of desired MicroCable. Dura-Line recommends a fill ratio of 50% to 75% for optimal cable placement performance. Several factors impact jetting distance including the condition of route, bends, and equipment.
✦ CONDUIT MARKINGS Permanent marking along MicroDuct includes: material, relevant standards, production info, and sequential feet or meter markings. Custom options available.
✦ CO-EXTRUDED Lining SILICORE ULF (Ultra-Low Friction) is co-extruded inside the HDPE wall creating a slick, permanent, interior lining. SILICORE ULF exhibits no loss in performance over time or in extreme temperature conditions.
✦ INTERNAL RIBS Standard (except 3.5mm ID which are designed with a standard smooth interior).

† Safe working pull strength is calculated at 80% of tensile or breaking strength.
* Unsupported Bend Radius guidelines should be followed during the installation process. The Supported Bend Radius are post-installation measurements.

Numbers can vary based on the path of the existing conduit, bend radii, elevation changes, distances, and installation method.
Application
APPLICATION(DI/DB) If a MicroDuct size has a thicker wall, it is recommended for direct bury (DB) applications either alone and will maintain optimal fill ratios for faster, easier installations. If the MicroDuct size has a thinner wall, it is optimized for placement inside an existing conduit, like an Over-Ride or populating an existing conduit. The direct install (DI) product is chosen where protection is provided by the existing conduit and space is more sensitive.
