Nylon Splicing, Step-By-Step

Before we jump into the how-to, let's cover why you should choose LinesToGo for your replacement lines. Our entire range of fuel lines are engineered for durability, flexibility, and corrosion resistance, offering a superior alternative to stock lines - all with consistent pedal feel and long-lasting durability. Check out the video above or step-by-step instructions below to see exactly how to splice your new LinesToGo nylon brake line onto your vehicle’s existing line with precision.

  1. Align the Lines: Start by lining up the new LinesToGo nylon brake line with the original line at the steel section. Find a straight, parallel section where both lines match up perfectly. This ensures a clean connection for your brake line splicing.
  2. Mark and Cut with Precision: Mark the spot where the lines align. Using a sharp razor blade, cut both lines at the marks to create smooth, clean edges. Pro tip: A razor blade minimizes jagged cuts, ensuring a tight fit. If the new line’s end already aligns with a straight section, you may not need to cut it, saving you time.
  3. Connect with Shark Bite Fitting: Use the supplied shark bite fitting to join the new line to the original molded nylon line. Push the lines firmly into the fitting until they’re fully seated. This secure connection guarantees leak-free performance and reliable brake system maintenance.
  4. Double-Check Your Work: Ensure the fitting is snug and the lines are properly aligned. A secure splice means safer braking and peace of mind on the road or trail.
