New improved style valve stem for the Reximex Mito air pistol.
Fitted as standard to UK Mito models from 2025 onover.

Retrofittable to earlier versions – replaces old valve stem and the valve seat – now seals directly to the action.
If fitting to an older version with valve seat you will need to remove the old valve seat before installing – this can be done by carefully screwing a wood screw into it and pulling it out.
