I folded it and mande a small incision with a pair of my whifes nail scissors and then i went along the small circle untill it was half the thicknessYou're going to make a lot of people happy with your discovery of the Cubis coil seal! How did you manage to cut the thickness in half?
The seal is on the top of the cubis coil and you can use a pair of curved tweezers to get it out and the same tweezers come in handy to place the seal on the Sireren's airflow tube.
It fits and seals it perfectly , was lucky to have some of my whife's old used Ego Aio coils .
