Sometimes when you operate your SodaStream, the drink does not come out fizzy enough, or you can hear gas escaping on the inside. This may be an issue with the internal air hose. This is a small piece that is part of the inner machine setup. The hose is what helps the carbonation process, it connects the carbonation bottle with the nozzle on the main loader tab, and if it is damaged in any way you may not be able to use your device. In this guide, you will see how the hose can be disconnected and replaced if the need arises.

Thanks for the guide, but i currently have this issue where the hose needs to be replaced, but no way of sourcing a spare part? Any clues anyone?

Nathan Roberts - Contestar

Did you ever find the part for your machine?

nagjoinslipknot -

Where would you get this part

magnolia_ca - Contestar

Exactly the same problem on my Source, but I can't find spare parts anywhere.

Has anyone found where to get them from in Australia?

I’d also love to find a way to buy this part!

dougsimon - Contestar

Any sources for the part? The one I have has a plastic nut that broke.

Jim - Contestar

Two things: first, before you disassemble your unit, try this: https://m.youtube.com/watch?v=st4d6drjVe...

Second: It would be _extremely_ useful to have some re-assembly photos. There’s one internal part that’s not shown, and it flew out when I took the halves apart. It’s the thing that fits between the two arms that stick out at the top (and provide the upward force for sliding front of the unit). The part in question has rods that fit into holes in each half, and the smooth, curved side faces toward the front of the unit, just behind the blue thing with the brass pieces.

Mark Pemburn - Contestar

That YouTube link is amazing. I think that is probably the issue everyone here actually has.

Thank you.

Matt Lamon - Contestar

What? No; the symptoms of a ruptured/disconnected hose (the topic of this repair) guide are totally different (i.e. the total opposite) than the symptoms of a clog or restriction (the topic of the YouTube video). Presumably everyone here is here because they have the symptoms of a ruptured/disconnected hose.

Joe Elliott -

Like half the comments here, where do you get the hose? The article has links for all the tools but under the 'Parts’ section says None Required! Kinda hard to replace a hose without a replacement!!!

Joseph Miloshevsky - Contestar

One of the nut on the hose broke (on my machine, this piece is in plastic instead of metal).

Did someone try to stick the hose directly on the hole? If yes, which glue did you used? Epoxy?

Sébastien Rougier - Contestar

Same thing happened to mine. Not even attempting epoxy, as I don’t know anything that would work and seal it due to the compression fitting design. I would simply replace it with what looks like the “update” one with metal tube nuts. The compression fitting is a very small metric one as a 3mm hose and M10x1.0 threads for the nuts

So to reiterate, what’s the P/N for this hose? A replacement guide is useless without being able to get that part.

Tim Spencer -

Has anyone managed to source a replacement nut for the plastic ones mentioned by Tim Spencer above? With a hole for a 3mm hose and M10x1.0 threads? I’m in Toronto Canada and have 2 Sodastream Crystal models with a broken plastic nut! Thanks!

(sorry for posting this twice, but just joined and now realised I can reply directly to a specific post)

Eric -

Is there a place I can purchase the air hose?

evontam - Contestar

Same problem here. Can't get the spare part in UK.

Same here. No replacement parts available….

Paul - Contestar

Still no source or modification for the delivery hose?

Eric - Contestar

It’s not M10x1, it’s 3/8”-28, i.e. BSP.

And I think I’ve found a marine component from which I can fabricate replacement hoses, but before I spend $30 to ship pennies worth of hardware halfway around the world, would anyone else like to buy a new hose assembly if I import enough parts to fabricate several of them?

Joe Elliott - Contestar

Would I need a full hose assembly just to replace the broken plastic nut? Or could I reuse the hose just cutting off the old ferrule and adding the new compression nut (if we were actually to find one)? Not sure how much difference it makes but I've got a sodastream Crystal. I don't really know much about the standards but I've found that a 1/8” FIP thread fits on smoothly to the receiving plastic part the hose connects to. Unfortunately, no luck finding a compression nut with that kind of mouth and an 1/8” OD tube. I'm definitely interested if you've found something to work!

Eric -

Full hose assy vs. just replacing the nut is an open question; I went ahead and ordered two nuts (and I have what I believe to be suitable tubing on hand), but I may try just replacing the nut first. However, this necessitates shortening the existing tube slightly (i.e. cutting off the part with the existing ferrule stuck on it), and I’m afraid it may end up flexing the tube too much and rupturing the tube. (I don’t know the differences between SodaStream models, but if yours doesn’t require the tube to flex every time the machine is used, you may have more flexibility (no pun intended) to just replace the nut.

Be careful with the FIP—if I understand, that’s the female variant of what I’d call NPT and is a tapered thread. So it may appear to fit smoothly for a couple of revolutions and then start chewing up your plastic threads! (I held up a male 3/8”-27 pipe thread fitting side by side with the SodaStream part and their threads did NOT line up perfectly, with SodaStream being slightly finer, i.e. 28 tpi.)

Joe Elliott -

Nice ! I wondered the same about shortening the hose but it seemed to have enough length — we’ll see, you may be right though. I had a female to female 1/8 FIP (NPT) and it screwed on seemingly very smoothly to the sodastream — hope I haven’t inadvertently damaged it, though there was absolutely no resistance so seems ok. Unfortunately, that F-F adapter would force me to use some male adapter with a compression fitting on the end of it and that’s just too long for the tight space in the sodastream. Let me know if things work out for you once your nuts arrive. Out of curiosity, where did you order them and where are you located? Thanks for your insights thus far!

Eric -

Nuts finally arrived, but I was skeptical of the included ferrules, so I tried to re-use the existing one—hose blew out right away, as feared. But I knew there was no way I could tighten the nut down hard enough to sufficiently deform the new ferrules without destroying the machine’s plastic threads, so I first tightened the new nut and ferrule into another fitting, then backed it off and tightened it onto the SodaStream, just tight enough to seal the already-deformed ferrule. This is all with the original hose cut short, by the way—we’ll see if it lasts.

I’m in Seattle. I ordered the parts from asap-supplies.com; what you really need is one of their part 303931 and one of their 303841, but the former was out of stock when I ordered, so I just ordered one of 303500, since it comes with two nuts and two ferrules. But the ferrules it comes with are different (303831) requiring the aforementioned ‘hack’ of using the double-male fitting (which I was going to throw out) as a tool to pre-deform the ferrule.

Joe Elliott -

What I should have said last night is that—assuming my slightly-shortened hose doesn’t fatigue and fail within the next couple of days—I’d be willing to sell the extra nut and ferrule that I have, and the fitting they came with (which needs to be used as a tool to pre-deform the weird chunky ferrule prior to installation on the SodaStream’s plastic fitting).

Joe Elliott -

I also found this: https://www.alliedelec.com/product/rs-pr... But by the time they responded to my inquiry to confirm the correct female threads inside the nut, I’d already ordered the aforementioned parts from the place in the UK. And I don’t know how suitable the included ferrule on this one might be.

Joe Elliott -

There is a missing piece in pictures - it is a pivot on top of the air valve assembly it will fall out in step 18 when the two halves of the frame are split. It has to be installed when the halves are reassembled, not sure how to post a picture here but it caused me to have to disassemble and figure out the exact position.

I fabricated a new internal aeration hose with these components:

Use the old ferrules as an adapter between the old fitting and the new ones

Brian Caufield - Contestar

In case my earlier comments were insufficiently clear, this is the direct replacement for the failure-prone tube nut: https://www.asap-supplies.com/fittings-v...

Joe Elliott - Contestar

So I just read your previous posts where it looks like you are re-use the old hose. What about the ferrules? Do they cone with just the nut or do you they come with that male to male tool as you called it? I devised my solution before I saw your link to the nut/fitting. That may have swayed me but I like where my approach uses a new hose ($.22) and metal fittings that can crimp it properly. The larger brass fitting don’t seem to get in the way and the hose can be a long as it needs to be.

Brian Caufield -

In my case (the lone nut linked in the above post was out of stock), when I bought the male-to-male fitting (which fortuitously became the swaging tool) that came with two nuts, it also came with two ferrules, so that was all I needed. Now that the lone nut is back in stock at that website, I’d recommend buying a more conventional ‘olive’-style ferrule, and maybe it won’t need to be pre-deformed against a metal fitting prior to assembly.

And yeah, I was sort of torn between re-using the hose (shortened ~6 mm) and making a new one with tubing I had on hand. I decided to try the former first because I didn’t have specs on my tubing; looking more closely at my tubing, I’m pretty sure it’s this: https://www.festo.com/us/en/a/567945/?q=... —food-safe pneumatic tubing with a 145 psi pressure rating and 0.25” minimum bend radius—given that the product I bought included two nuts and ferrules, I probably should have just made a new hose!
