A repair device and method comprising a canister having an internal cavity, an input connecting valve, an output connecting valve, and an output hose for purposes of inflating a pneumatic device such as a flat tire. The utility of this device is as a readily available bridge to connect a deflated tire with any available air source such as an inflated tire. A sealing mixture may be stored in the internal cavity of the canister for injection into a leaking or flat tire to effect repairs by sealing any leaks. When attached between an inflated tire and a flat tire, the sealing mixture is injected into the flat tire by the pressure of the inflated tire and the flat tire may then be inflated.
