UFS: a simple but great mod

[Giulio]

This is a very simple mod made by "mikkos45", a member of an Italian forum. That promises results very rewarding.
It's sufficient to insert in the mouthpiece of the UFS an oring.
This guarantees a more constant aspiration of the eliquid and minimizes the adjustments air/eliquid










I am using by two days this mod and the results are excellent: increased stability of the system, use of the liquid to the last drop and minimized the frequency of adjustments.
Highly recommended mod...try it!

No need of the original o-ring between mouthpiece and cap Giulio?

Wow, very interesting, I have to try this, What do you think of it Imeo?

[Giulio]

the original remains in his place, this is an addition.

 

[Wylie]

Pardon my ignorance, but is the 'mod' the mouthpiece? Or is it the insertion of an O-Ring into a regular SS mouthpiece?

 

[Giulio]

It is the insertion of an O-Ring into the UFS mouthpiece.

Any idea what size o-ring that is? Haven't had any luck on a good fit with my current stash.

Do you know why it helps? just curious for if I ever get one.

This is the link to the discussion, if this is not allowed by the rules of the forum i delete it.

Interesting, It looks like it seals the gap between the atty connection and the upper part of the mouthpiece causing all of your draw to be purely through the atomizer even when the mouthpiece is loose. So the tank can bubble and still feed the atomizer freely. I like this idea... I wish I had an O ring to fit, but I am definitely going to try this!

The inside diameter of that space is .409 inches or 10.3886mm if this helps anyone. (I used my Calipers)

I just find the perfect o-ring for that it's around 10/1.5 and it seems i can't open liquid more than 1/4 maybe little more of a turn.
But i just start to vape it on 3.5 ohm atty on 6 volts and we'll see how it works out

I tried but IMHO UFS works better without this o-ring

It's true, if you want to open it more loosen the mouthpiece, open the liquid and then close again the mouthpiece.

Well now i'm a little green in my face from sucking constantly for couple of hours and
i'm going to say that i'll stick with it for a while couse... i don't know... but it works for me i think.
Stability and constant seem better and now when i take those primes with air closed, liquid is
immediately in atomizer and ready to be vaped away. All in all I love UFS and love to play with it
and it works great with this mod or without it. But like i sad, i'm gonna stick with it and
Thanks Giulio for a tip

Ok. After all day with this little mod i'm done with it I mean it works ok but i miss full
liquid control and if nothing i realized small error of mine when i take primes with air closed(too much liquid open).
Finally there's no significant improvement and liquid control is what UFS is all about! Cheers
