Are bottles SUPPOSED to unscrew from regs?

[cris8762]

Well, i accidentally screwed my centerflag 68/45 preset on too tight and when i went to unscrew it the bottle came unscrewed from the reg!

this alarmed me so i called the company that hydroed my tank, and they said they dont use loctite on the regs and that it was normal....this alarmed me somewhat because now my bottle unscrews much easier than it did b4

is this normal?

can i loctite it on to make sure it stays on?

also, if there is air in it, will it be much less likely to unscrew?

thanks,
cris

Yeah it can happen, DO NOT USE LOCTITE!! = bad bad idea !

yup tighten it by hand pretty snug and the air will make sure it wont unscrew, i wouldn't worry too much.

I don't know what anyone else says, (and you know the old cliche about opinions)...but both of my MaxFlo's and my Angel AiR did that. I asked about that and they acted like it wasn't a big deal...so I don't know what to tell you.

Some people will say just to be safe take it to an airsmith to have the valve put back on but it is safe enough to just screw it back on by hand and it should be fine.

one of my friends tank did that but he just got a lot of superglue and tephlon tape and it works fine now!

I wouldnt feel safe with my tank with 3000psi be able to uscrew by hand...but im assuming as long as you have air in it, it wont unscrew

Another thing you should never USE!!! You should not use teflon tape or superglue, thats not a good thing

curious

Now, I'm curious, why wouldn't just a dab of non-permenant loctite be fine, just to lock it down while unpressurized?

I have been wanting to change my tank but keep the reg for a while, but I can't find a 68/3000 carbon fiber body that isn't about 10 bucks less expensive than buying it with a reg, it's crazy.

Yea I agree that the pressure when it is filled will keep it super tight, you shouldn't have to worry about it.

And what the heck would make someone think putting super glue on their tank would be a good idea???????? I could see if a newb thought of teflon tape... but glue!!!!! eegag!

Ok, unfortunately the pics are now missing but read this thread and then think if you really want to put thread lock on a reg.

Anything more than 50 psi in your tank and you won't be able to unscrew the tank by hand. No worries, At 3000 psi, you wouldn't be able to get it off with anything.

thanks for all ur help guys

i was just kinda worried when it came off, i was like "OMG I BROKED IT!"

Do NOT use loctite or superglue! When the tank gets hydro'd they (or you) will need to unscrew the bottle from the reg.

Why not use a little loctite/superglue/teflon tape? 1) You don't need it if there is pressure in the tank (already stated) 2) If it does get stuck and require heavier tools for removal, you may damage the threading.

This should not be an issue since you keep your tank pressurized all the time... Right? Without pressure in the tank, you allow water, dust, smurfs, whatever into the tank. If I'm not mistaken you need to keep the tank pressurized according to DOT specs. (Yes, I know transporting while pressurized is a no-no).

Use a small amount of BLUE (non-permanent) Loctite. As long as it has had time to cure, it will not get into the reg.
