O-rings for Swift Fx?

[dtsm]

I've been swapping back and forth from Fx and LT for the past couple of weeks and consistently get better numbers with the LT. LT seems to seal much better for me but I prefer the Fx for overall comfort. Unfortunately I traded my M size pillow for another Small so can't determine if maybe a large size will help. I am getting a Medium sometime this week and will try.

In the meantime, has anyone had a need to insert o-rings like some folks have done with the LT? viewtopic/t32164/New-Swift-LT-mask-expi ... o-far.html

Would maybe o-ring help with seal? (Btw, already tried the lanolin)

can u explain the purpose of the O-Ring? I am new to this and I use the fx and like it very much for its comfort! I did notice that the medium was a little tights for me, so I switch to the small and it fits perfect.

it would help if you were to identify which post on that thread it was

if you look at the post right next to "by person x" there is a little box, click on it and it will show the exact post you in your location bar for you to copy and paste

Thanks for the tip, never could figure it out before!
