A sealant device for a sealant for sealing a vehicle tire, comprising:

• a housing for containing the sealant, the housing including a housing section and closure unit operably coupled to the housing section, the closure unit having first and second openings, wherein the first opening is configured as an air inlet for permitting air into the housing, and the second opening is configured as a sealant outlet for permitting the sealant to exit the housing,
• a tube having an internal passage, the tube being arranged to fluidly connect its internal passage with the first opening of the closure unit, wherein the tube extends into the housing and has a tube outlet within the housing through which air can flow from the first opening through the internal passage and into the housing,
• a first sealing element configured to close air flow through the tube outlet when in a closed state, wherein the first sealing element is movable to an open state in response to air pressure via the first opening which thereby opens air flow through the tube outlet and permits air to flow from the first opening through the internal passage and into the housing, and
• a second sealing element that closes the second opening,
• a hose connector at the second opening for fluidly connecting hose to the device, the hose connector having an integrated cutting device configured to cut the second sealing element in response to insertion of the hose;
• wherein the second sealing element is configured as a destructible closure that is fixed in relation to the second opening and which is configured to only permit opening of the second opening upon destruction of the second sealing element via cutting with the integrated cutting device.
