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

Used one of these to replace the old worn out one on my 20+ year old SIGG bottle. It fits perfectly too.

Did not purchase these for a SIGG bottle but for dispensing bottle like those used by chefs for dispensing sauces and garnishes as they did not come with seals and leaked at the most inconvenient times. These sigg seals did the trick. Be aware that mine arrived in a plastic bag rather than stuck to a retail card illustrated on Amazon.

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.

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 😞

These provided an excellent seal on my Sigg metal water 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

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.

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.
