I remove the o-rings as seldom as possible...because they can stretch, and then must be replaced. All the o-rings I’ve replaced were due to being stretched, unintentionally, by me. Keeping them greased up is a real good idea; I’m not real good at remembering to do it, but $5 to oringsandmore got me a lifetime supply...only replaced 2 in 4 years, so....You can leave the o-rings on if soaking in ISO alcohol for a short amount of time.
Same here.I’ve retired all my CAPTIVE caps, except the one that came with the 2020m, SS tip. On that tip the CC indents actually catch on the top grooves.
Another downside to captive caps that slip down, is if like me, now and then I vape with the DV pointing down, as you insert into a hydrotube. Now gravity allows more cap slipping downwards.
For what it’s worth, I also have that nickel contact allergy, and have been able to use the steel dynavaps for years with no issue. (But don’t let me talk you out of the titanium...)On a side note, I tend to get rashes when I wear cheap steel jewelry (I guess because of the nickel?) and wanted to know if that reason alone is enough to go Titanium.
I just got mine Monday, and I had to clean it already yesterday. No, I didn't run half an ounce through it in two days--though I did probably toast about an eighth playing with my new toy.Since i got it I've run about 14g's through the Vong and it is time for a cleaning. I found no issue with cleaning the titanium lined stem. Only took 1 qtip with a little iso. Hardly any material got in there anyway.
Just thought i would update for those who were concerned. Ain't no thang!
Is there a difference in draw resistance between the models/caps?
I heard some complaints about the original 'M' having a lot of draw resistance
glad you made an account and enjoy your captive caps! however i don't think they need support as much as a little redesign/upgrade. personally i would love the vertical play removed/reduced as it brings nothing but inconsistency to an otherwise low tolerance system.I lurked on this forum for months. But I finally broke down and created an account because it is driving me nuts how little support captive caps get here. Some of you talk like it's an irrefutable fact that captive caps are worse than normal caps. I'm not here to argue, just to say that it's at least somewhat subjective.
I like the captive caps. On a 2019M, 2020M, and 2021 omni I like the captive caps. I have used 6 different captive caps and 2 noncaptive caps. I also like the noncaptive caps. Once they are on a dynavap and I'm hitting it I cannot tell the difference. It's a great experience. I love my dynavaps. Dynavap made me fuck combustion and I never even had that intention.
I hope everyone is having a splendid day!
