Grandesys used the time in the Corona Lockdown phase sensibly to develop a new seal. We have used other materials for this seal to change the properties of the standard rubber seal.
The properties of this seal are mainly the even better flexibility in contrast to the standard rubber seal, as hand washing paste, hair or other macroscopic bodies could cause a leak. This seal compensates for macroscopic bodies if they are not too large due to their flexibility and seals better thanks to this property.
This seal is currently still in the test phase and will be offered in addition to the standard rubber seal from September 2021.
