This brilliant little compact tire plug kit is entirely self-contained, with a push-on silicone end-cap that seals and stores spare repair plugs and other accessories inside the handle.
Dynaplug contends that most punctures from errant nails or screws usually are sized up to about 3/16” in diameter, or smaller, and that’s the range where this tool is meant to shine.
It works like this—first fix the steel insertion tube to the end of the handle. Then load a repair plug, made of a proprietary viscoelastic rubber-impregnated cord mounted to a pointed, non-abrasive brass tip that helps ensures ease of insertion. Then yank the tool away, leaving the shank of the brass insertion tip to catch the inside of the tire. Trickle a little water over the hole, and if the leak persists simply add an adjacent plug to seal the deal. Dynaplug advises no more than four plugs for a single hole. Once the leak is stopped, trim the cord flush with the surface of the tire.
This system differs than the traditional reamer and eyelet-hook with gummy rubber strips and sometimes a bottle of vulcanized glue in that, well it doesn’t need any of that stuff. No reamers (which Dynaplug contends can cause further damage to tires), no glue, no need for multiple tools.
