Adams Gas Cyclinder users! Can anyone help / explain what's going on here...

[TT0885]

Hi all,

Hoping that someone might be able to identify a problem that I'm having.

I recently purchased the strideways pro dual stage regulator alongside a 3.15kg CO2 cylinder from a supplier local to me who advertises for various uses including in planted aquariums.

Both products are advertised as having standard 'DIN 477' connections, however whilst they screw together there seems to be some sort of depth of engagement issue. The very end of the regulator - not sure what to describe it as other than a nipple, doesn't seem anywhere long enough to push against the back of the regulator connection - when this part is pushed in it releases the gas.

I've attached photo's of both pieces that I'm talking about.

I cannot work out which piece is wrong or if I'm missing something - does one of these items not in fact have a standard DIN 477 connection?

I know that there is co2 in the bottle and the regulator works, but I'm stuck here - anyone's help or suggestions would be greatly appreciated.

Many thanks
Tom

Hi Tom
Have you tightened the nut with a spanner?
Post another few images of the regulator attached to the cylinder!
You may have to remove the black collar as this may restrict the full attachment of the regulator to the cylinder.

Hi there,
Thanks for your message - I've attached some pictures of the regulator attached to the cylinder, but let me know if you need to see from different angles etc.
There isn't any clash with the black collar, it seems like the length of the cylinder attachment part is too long/ has too many threads - I've also attached a picture of just this for reference.
I have tightened the nut with a spanner but doesn't help.
Thanks!

All looks correct, the female part should have a little 'end float' until the nut is tightened, the end float will disappear when it bottoms out when tightening the nut, then the nut will get resistance as it compresses the washer and it will soon feel very solid. need to put quite a bit off tightening force and it tends to give a bit of a squeak in the final nip.

Hi,
Thanks for the message, if you see the attached picture, I think that even without the rubber washer, the nose/nipple of the regulator isn't long enough to reach the back of the cylinder part and release the gas.
I've put quite a bit of force on it and had someone else try too - however as above, I think that even if the washer wasn't there, there would still be a gap between the end of the 'nose/nipple' part of the regulator and the back part of the cylinder?

Hi Tom
The above part does not go inside the threaded part!
It sits on top flush, then tightens up with a spanner.

This is the correct configuration below.

Hi,
Ok understood, thanks.
However I don't understand how the gas gets released then, as it only comes out when the star-shaped piece in the attached photo gets pressed in?
When I connect it up as suggested and turn everything on, nothing happens because nothing is pushing on the described piece and so there is no gas flow.
Is there some other part on the cylinder that I need to do something to aside from just open the general 'tap' at the top?

 

[G H Nelson]

Where did you purchase the Co2 Cylinder from?

 

[TT0885]

A supplier called Adam's gas - CO2 for Aquarium Plant Growth - Adams Gas

Not that I'm aware of, I'm not an Adams Gas user being a bit in the dark about their cylinders!

 

[TT0885]

No worries, thanks for your help anyway - I've sent them an email with some of these photo's to see if they know the answer.
Thanks
Tom

Thread 'CO2 gas cylinder help'

7 Mar 2021

Hi everyone,

I got a CO2 cylinder from Adam's gas Refill 1.5KG CO2 Gas for Hydroponics & Aquatic Growth from Adams Gas
I tried to use it with a CO2 art regulator, that's has been working fine with a Sodastream cylinder and adapter.

However when I connect the regulator to this cylinder nothing comes out. The high pressure guage reads zero, but certainly comes up with the sodastream. So it has to be the new cylinder. I don't think it's empty.

I've attached photos of the cylinder and the outlet. I've slowly opened it without anything attached, but can't hear anything. I'm not too...

I use Adams Gas 1.5Kg cylinders and a Strideways Dual Stage and don't have this issue. (You have the bigger brother(s).

I cant really see a difference, or imagine what the CO2 cylinder would be different unless the valve is faulty on the cylinder. The only way to test (VERY VERY carefully outside) is to slowly open to see if gas escapes.

Including a picture in case it trigger something.

 

[TT0885]

Thanks for this, could you send a picture of what the inside of the co2 cylinder attachment part looks like - ie does it have the diamond shaped thing that needs to be pushed in to release the gas?

 

[TT0885]

UPDATE RESOLVED:
Thanks for all the help, I went back to the stockist this morning and picked up a 1.5kg bottle - this one works!
On close inspection, this one does in fact have a shorter connection distance to the cylinder than the 3.15kg bottle - bizzare!

It seems the issue was simply depth of engagement, the larger cylinder also had a longer connection point and the regulator 'nose' just was not long enough to engage with the diamond shaped piece at the back and release the gas. This smaller cylinder has a shorter connection (only by about three threads) but allows the regulator nose to engage properly and release the gas.

Very strange as couldn't see any advertising differences between the two cylinders.

 

[G H Nelson]

Good stuff glad you got it sorted out!
Thanks for getting back to the UKaps for future reference.

There should be a thick nylon washer which acts as a spacer and seal, it should come with the regulator but you can get spares.

I use the 3.15Kg cylinders from Adam’s gas and have never had a problem. There is nothing inside the thread that need to be pressed to release the gas, so not sure what was happening with yours.

This insert looks to be removable.

Same here, using Adam’s gas for many years and it was always as simple as just connecting regulator, opening bottle valve and just checking for any potential leaks. That’s it, there is nothing to press or touch or remove.
