SIGG KBT closure, spare part for SIGG drinking bottle, spare closure for leak-proof children's drinking bottles

These provided an excellent seal on my Sigg metal water bottle.

I'm sure this is a great product, unfortunately it doesn't fit Chilly's water bottles. Probably my mistake for not reading the description properly, but just be warned if you have a Chilly's bottle.

Fit the older Sigg 1 litre and 1.5-litre bottles I had lying around from the 90s. They seemed expensive at first but they do fit and are drinking water grade so safe to use.

Bought these to replace Chilly bottle seals as the description said they fitted any bottle. They fit the lid but they are too thick and the bottle won't close when they are in place. Waste of money 😞

Like many others I hoped this rubber seal would fit my Aluminium drinking bottle (similar to a Chilly's bottle).I measured the seal that was broken and it seemed to match the 3cm diameter that is shown in the product images. Therefore I assumed that it would work.The '3cm' diameter actually measures 33mm, whereas the seal I'm looking for is 29mm. These 4mm make a huge difference and means that the seal won't fit my bottle.I've included the actual measurements of the seal which should hopefully help others decide whether this is the right seal for them.

I bought these seals as I had a leaky Gelert bottle and these were the only replacement seals I could find. They fit well and they work! Much better than having to buy a new bottle.

As others have stated, these seals are designed for KBT (kids bottles) and also work well with older two-hole tops. If your top is newer and has the moulded-in rubber strip then the seal is not removable and these won't help you

Excellent quality product to replace original seals that had become brittle and started to leak.
