Sodastream Stainless Steel Bottle Caps Twin Pack
You Saved $1.25
Small but mighty, our bottle caps create a hermetic seal when used with our carbonating bottles. That means that your sparkling water can stay carbonated for up to 2 weeks in the fridge if left unopened! Sold in a twinpack so you always have a spare.

Don't fit E-Duo
They don't fit the E-Duo glass bottles. Several other reviewers have mentioned this and have suggested this be noted in the item description. Customer service agents have even responded to some of those comments, claiming they would do so. As of June 2026, there is still no warning that they won't fit those bottles.
Don't work
I ordered the steel caps for our new E-Duo but they don't work on that particular model. You should note such on your webpage. My ratings below are for the caps under discussion and not the bottles mentioned in the question.
Not what I thought
Does not fit my glass bottle, only the plastic bottles and I didn't want the plastic bottles. That's why I ordered the glass bottle.
Excellent product and price, outrageous shipping $$$
Shipping costs 3-4 X the price of the merchandise! Shipping was fast, but come on!
