The deflation button tool for the Mares inflator is used to remove and insert the small plastic ring together with its O-ring located in the bottom part of the inflator.
 
After removing the inflator from the jacket push in the side of the tool with the small hole in it and the deflate button is removable.
 
For installing the deflate button use the other side of the tool with the bigger opening by placing the small plastic part in it with the O-ring on top.
 
The Mares inflator deflation button tool is precision machined from white acetal.
