Bored,so...
Waiting for the ready rebuildable kits
I threw a bridegless 510 atty on the small base a couple o-rings and the long neck...goes as follow:
1-2 similar sized o-rings,1 stretched against the knurled ring,the other loose against the top of the center part,just sitting there;
1st one prevent leaks,2nd ensure there is no leaks at all.

The setup:

The result:

As expected,vapes like a .... without any leaks.
Not advanced engineering but i was bored.
P.S.
I am still bored.
