Jagwire Pro Needle Driver

The Jagwire Pro Needle Driver is compatible with standard 5.0mm and 5.5mm hydraulic hoses. It is designed to handle most common mountain and road bike brake systems, but it is not intended for use with non-standard hose diameters.

Installing a barb by hand or with improvised tools often leads to bent barbs, damaged hose ends, or uneven seating, which can cause leaks. This tool uses a sliding piston to ensure the barb enters perfectly straight, creating a secure, reliable seal every time.

Not at all. The tool features a long lever arm that provides significant mechanical advantage, making it much easier to press the barb into the hose compared to using standard pliers or a bench vise.

The integrated needle starter pin holds the barb securely in place before you begin the pressing process. This prevents the barb from slipping or tilting, ensuring it is perfectly aligned with the hose opening before you apply pressure.

Yes, the tool includes adjustable tension settings to accommodate both 5.0mm and 5.5mm hoses. Simply adjust the clamp to match your specific hose diameter to ensure a secure grip without crushing the hose.
