Mushroom style inserts are designed to “fill the injury” in passenger or truck, radial or bias-ply tyres.
The Plug Kit makes repairing tyres easy and convenient. No great force is needed to insert the plug into the injury; the metal probe of the plug gun slides smoothly into place, the plug can be applied by squeezing the handle on the plug gun a few times. These inserts will fully vulcanise either chemically or in a heat curing system.
