The Fremco Blowing Tip, 10 mm, OD 10.5 mm (vendor part K10S, Millennium part 543976), fits over the cable end and reduces drag as it travels through microduct during a jetting run, helping crews reach longer placement distances on a single blow. Sold in packs of five, it is sized to match 10 mm cable for a snug fit that keeps the tip from working loose mid-run. It works with Fremco MultiFlow and MicroFlow cable blowers used across most fiber OSP builds. Keep a range of tip sizes on hand alongside gaskets and duct clamps for whatever cable diameter shows up on site.
