The GM Masticbox SADURR® O-ring is made to measure so as to fit perfectly into the groove provided for this purpose at the level of the internal part of the Masticbox SADURR® valve cap. It creates a perfect seal between the Masticbox SADURR® valve plug and the Masticbox SADURR® receptacle during the air vacuum carried out using the Masticbox SADURR® manual pump.


Any degradation observed requires the replacement of this part to maintain optimal efficiency of the Masticbox SADURR®.
