If the gun adapter is too short to reach bottom of the DIN Threads and air leaks this washer can be inserted into the adapter so the o-ring makes contact with the washer creating a good seal. Once inserted the washer will make contact with the o-ring preventing air from leaking.
You should only need one but you can stack them to fill a larger gap if needed.
To remove you can use a small L shaped allen wrench or a curved pick to pull it out.
