Wirefy Heat Shrink Tubing Kit (adhesive-lined, assorted)

Any time a wire on an e-bike is repaired or a connector is replaced, the joint needs to be sealed against water and vibration, and adhesive-lined heat shrink is the right way to do that. Wirefy's assortment kit has a range of diameters in a labeled box, with an inner glue layer that melts and seals the joint when heated. A heat gun is better than a lighter. It is a basic consumable that every home mechanic doing any wiring should have. One safety rule: if a repair involves cutting into the main battery or motor wiring, or there is burnt smell or melted insulation, stop and get an E-Bike Assessment.

Best for: Sealing repaired signal wires · Insulating crimp and solder joints · Weatherproofing harness repairs
