No mechanic. No dismounting. No waiting. Back on the road in under five minutes.
Identify the puncture and remove the nail or foreign object. Insert the Rasp Tool and ream the hole clean with a firm in-out motion to prepare the surface for sealing.
Thread a CATFISH® repair string through the eye of the Insert Needle. Apply sealing lubricant. Push the needle firmly into the puncture hole until only a small portion remains outside.
Pull the needle out - the plug stays locked inside the tyre. Trim the excess string flush with the tread using the cutter. Re-inflate to correct pressure. You are done.
