This kit fits most oil needles, including Shimano, SRAM, Magura and Tektro, and works with tubing that has an outer diameter of roughly 5 to 5.5mm, which covers the great majority of hydraulic brake hoses used on modern bikes. Always double check your specific hose's outer diameter and needle style against these specs before starting a cut.

The kit includes a press-in handle, main body, dual-purpose thimble, blade, tubing cutter, tubing chuck and fixed handle. You start by using the tubing cutter to trim the hose cleanly and squarely, then clamp it in the tubing chuck, install the olive head, and finally use the press-in handle to seat the oil needle into the hose end for a leak-free connection.

Yes, cutting a hydraulic hose introduces air into the system, so a full bleed is required afterward to restore firm lever feel and remove any trapped air bubbles. Our Shimano Brake Bleed Kit and LEBYCLE mineral oil are useful companions if you are working on a mineral-oil system, while DOT-fluid systems need matching DOT fluid instead.

This is a more advanced home mechanic job since it involves your bike's braking system directly, but with careful attention to the included instructions covering cutting, olive installation and needle pressing, a patient home mechanic can achieve a professional-quality result. Take your time on the cut and clamp steps, since a clean, square cut is what makes the final seal reliable.

Whenever you fit a new handlebar, stem, or make other cockpit changes, brake hoses often need to be trimmed to the correct length so they are not too long and floppy or too tight and restricting steering. This kit lets you make that adjustment yourself rather than needing a shop visit every time you tweak your bike's fit.
