I forgot to lower my reg before pumping so I took off the tank to find I tore a o ring. I have spares from the hand pump kit but the umarex does not include spare o rings. Does it have to be exact size? The one I have is slightly thicker with a smaller inside diameter, I'm going to try and find a replacement at the hardware store. Is there kits I can buy? Also am I only able to fill the tank off of the gun to a certain psi? It started leaking out the non fill end around 2k psi and I lost all my air. Haven't tried pumping it up again. Doesn't help I got the gun today in the mail and it's freezing cold, maybe that weakened the seals?

First off, this is a known problem with the SPA M60 and Zelos, both bottled versions as well as tube versions.
The issue at hand is the 70 durometer orings used are too soft for continual bottle/tube removal under pressure.
I do have o-rings on thier way that I will be testing when they arrive but they may not be user-replaceable without a witches hat.
These are made from urethane and are 100 durometer so they are very stiff and hard.
This may allow constant removal but they may also chip, evaluation is needed.
I suggest looking for 90 durometer Viton orings locally if available. I do not have the ID or CS on hand, I'm on a job currently.

I guess I should keep the bottle on all the time, I did notice it does kind of come off easy enough wondering if Teflon tape on the threads a bit should keep the bottle on better not letting it twist off as easy. I'm not too concerned about it leaking out the non fill end it's holding 1k psi as I put a few drops of super lube in it let it sit and re pumped it just to 1k. My take from this is just leave the damn tank on, I do want to do a bottle in the future.

I strongly recommend you dont use teflon tape, I use Vibra-Tite on threads where you want it to stay put but still want to turn it if you need to remove it. I use this on ALL of my triggers.
