Description Zefal Tubeless Plugs will seal a 1-5mm sized hole in your tubeless tyre. This plug kit includes 6x tubeless seal strips (but no tool!). 3x 2mm diameter strips & 3x 4mm diameter strips. If you run tubeless tyres we absolutely recommend having a road-side solution for the inevitable otherwise day-ruining puncture. Please note, these are plugs only, no tool included in the kit, plugs are rated to 87 PSI maximum pressure. Directions for use from Zefal: Place the tyre plug on the punctured tyre: 1. Turn your wheel to find the air escaping. Extract any object still in there causing the puncture. 2. Insert the plug through the tool. 3. Insert the needle tool into the hole. 4. Forcefully pull out the tool by turning your wrist. 5. Re-inflate the tyre if required. The plugs supplied in these kits are recommended for punctures between 1 and 5mm. For smaller punctures, we advise you use the Z Sealant range and for anything larger, to change the tyre.
