CO2 art regulator washer doesn't fit

Hi all,

Sorry about this newbie question, I just got my CO2 art Pro-se series regulator and step one:

Place washer between CO2 cylinder outlet and regulator's stem (inside regulator's nut)

But I was leaking really bad even if i throw that washer in between the Co2 tank outlet and inside the nut

I found this thread https://www.plantedtank.net/forums/9...lp-needed.html , but my head looks a bit different than that picture.

The video online shows a pretty different connection nut, the tip from the video looks like this





^^ notice that the washer seems to fit that silver rim inside.

Whereas, the tip of mine....I really couldn't figure out how could that happen? Am i suppose to screw it really tight that it will break something? cause I don't see how the washer can fit with that tip at all. This is how mine looks:





I don't have a spanner/wrench big enough for the nut, i did use the duck tape trick to tighten it, perhaps it's just not tight enough? Every time it leaked like immediately, I could literally feel the air coming out, so it's definitely not right.

This is my gas tank btw:



Many thanks for your help!!!!

That "silver rim" is unnecessary. You are supposed to place that nylon washer (gasket, actually) inside that huge nut that attaches the regulator to the CO2 cylinder. Of course, first you have to slide that nut forward so that it forms a "cup" at the end of the regulator intake.

Then, as you tighten the nut to the cylinder, the nylon gasket will get squeezed between the regulator and the cylinder.

The nylon gasket usually fits snugly inside that large nut, which is what keeps it centered during the tightening procedure. Is yours a good match to the inner diameter of the nut? If it is, you have nothing to worry about. If the nylon washer is notably smaller, then something might be amiss here.

Well that type of washer isn't err "usual" for that type of CGA but doesn't mean it won't work..
Trick will be lining it all up and tightening it TIGHT...very tight.
Not sure if you can actually do that w/out a wrench (pipe/crescent/box/vice grips ect)

This is your problem. Go get a proper wrench.

Many thanks for the quick reply!

I am not sure if it fits perfectly, see the photo - there's some gap



Though I will go get a bigger wrench and try it again!

Gap won't matter. not really in the sealing area. You need the plastic to sort of conform and seal the flat face..
will make it more difficult to line up correctly though.

Really should get the "more correct" seals.
Actually most refill places will give you the paper kind for free.
do not recommend them though it's a YMMV type choice. Def not reuseable.
Plastic ones last forever. Think my oldest is 4 years old and prob 10 tank changes.

Thank you so much for the explanation!

The washer comes with the regulator so i suppose it should fit. Perhaps if I tighten it hard enough, it would squeeze that piece of washer and fill up the gap or something... Dunno yet as all the hardware stores are closed and i would have to get a proper wrench tomorrow :P

I do have a piece of ring/rubber that fell out when i took out the OLD regulator...likely a seal/washer from that old regular that I'm replacing. Should I throw that in as well? So it goes regulator -> washer -> that piece of rubber ring -> Co2 tank outlet?

That piece of ring/rubber is the right one in the pic, and the washer that comes with the CO2 art regulator is on the left. What do you think?

Hmmm ..looks like part of a broken perma seal to be honest.. No you don't want to use it..
Perma seals screw into the tank valve face..
In that case it's the only seal to the regulator flat..

BTW: Never assume it's the correct part. Not when it doesn't fit perfectly..
W/ yours it 'looks" like they had another style CGA at one point..

Thanks all for the reply. I googled around and found some tank with similar CGA 320 outlet https://www.morebeer.com/products/co...-aluminum.html . So i assume the tank side is good.

As for the regulator side, I will try to get a wrench and tighten it hard hopefully that would do it

I've been using one of these for about a year now. I didn't have any issue getting it hooked up. You do have to crank that plastic washer down using a wrench. I don't mind admitting I was terrified I'd break something. Also I found a slow leak around the top of the bubble counter. I ended up replacing it with a one made of brass.

Yesterday, I purchased a CO2arts Pro-Elite Series regulator and a 2nd manifold to run two aquariums off the same CO2 tank. This will replace the SE.
