An inflatable article repair and inflation kit comprises a canister of sealing fluid; an inlet connectable to a pressure source and connected to the canister; a selector valve interposed fluidically between the inlet and the canister; a conduit connected to the selector valve, in parallel with the canister; and a flow resistance of die selector valve and the canister to reduce the pressure in the canister with respect to the pressure in the conduit. The inflatable article repair and inflation kit ensures the best pressure into the sealing fluid canister.
