The Gun is a spring loaded device that drives the plug into the hole. The shaft of the plug expands under pressure to fill the puncture. The mushroom head of the plug seats on the inner wall allowing no air to escape. This insures maximum reliability from its' revolutionary design. It's easily stored - so you're always prepared.
NOTICE: The accepted industry standard recommended by the RMA (Rubber Manufacturers Association of America) requires that an injured tire be demounted, the interior inspected, the injury drilled out, and a plug and repair unit installed by a trained professional.
