This revolutionary tyre plugger device easily installs mushroom shaped rubber plugs into any tubeless tyre without the need to remove it from the rim. The gun device drives the plug into the hole as the handle is pulled. The plug expands under pressure to fill the punctured area. A firm pull on the stem with your pliers seats the mushroom head on the inner wall allowing no air to escape. Suitable for cars, trucks, trailers, SUVs and motorcycles.
