I was using my UFS last night and it instantly started leaking heavily into the collection
tank and flooding the atomizer. I took the whole unit apart and realized that the connector pin is missing 2 o rings

I checked out this
thread and see that I need the 2mm/1mm for inside the pin and 4mm/1.5mm for the outer part of the pin. I have searched this forum and google high and low and can not find any site that sells both o rings.
oringsUSA has the 2mm/1mm but not the 4mm/1.5mm. They do have a 4mm/1mm do you think that will still be sufficient. If not can someone tell me a site where I can just
buy these things in bulk and not have to worry about it again. I am going to try ace hardware after work but I think that may be a longshot. Any help much appreciated. Thanks.
