Ultra-Low Friction Lining by Dura-Line®
For more than 50 years, Dura-Line has been the worldwide leader in industry firsts. We were the first to bring conduit to the telecom industry; the first to manufacture ducts with pre-installed pull lines; and the first to offer longitudinally ribbed ducts, to name a few.
Now we’re proud to announce our latest breakthrough – SILICORE ULF – ultra-low friction lining.
The super slick, yet non-greasy lining provides 40% lower1 coefficient of friction than before. What does this mean for you? This means you can jet fiber optic cable up to 25% farther2 in conduit lined with SILICORE ULF, saving you a lot of time and money.
Because no one has time for friction.

-
40% Less Friction
-
25% Farther Jetting
-
No Lubrication Needed
-
Cold Weather Capable
1Compared to Dura-Line’s SuperSilicore-lined conduit. Internal lab testing performed on 1.25" SDR smooth-wall conduits. 60% lower coefficient of friction than standard HDPE without the use of wet lubricants.
2Compared to Dura-Line’s SuperSilicore-lined conduit. Internal lab testing with jetting of fiber optic cable in 16/12 mm MicroDucts. Your results may vary, as many factors influence jetting distances (e.g., bends in pathway, gravity, weather, etc.)
