The complete valve only is available as a spare part.
The valve insert is commercially available.
The valve cap -1- is provided with a seal (air-tight seal). Do not confuse with a commercially available valve cap! The shaft of the fastening nut -2- must point towards the valve foot, because otherwise the valve will not be secure. See Fig 2.
