## Description

Sigg KBT closure, spare part drinking bottle, spare closure for leak-proof children's drinking bottles : desertcart.co.uk: Home & Kitchen

Review: Great replacement to keep an old Sigg bottle going. - Used one of these to replace the old worn out one on my 20+ year old SIGG bottle. It fits perfectly too.
Review: does the job - 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 desertcart.

## Questions & Answers

**Q: What diameter are they ?**
A: External diameter 34 mm, internal diameter 28 mm. Hope this helps. GRB

**Q: The seals on my existing lids seem stuck fast. How do you change them?**
A: They shouldn't be glued so likely just a bit wedged in. As long as you don't cut into the plastic of the lid you can destroy the old seal to get it out. Maybe try soaking in hot water for a while first though and it should loosen it up.

**Q: Is it dishwasher safe?**
A: no

**Q: Are these suitable for use on a Sigg bottle storing fuel (Coleman fuel/white gas/Aspen 4)?**
A: As far as I know Sigg does not make fuel bottles so I doubt they would be suitable for a bottle storing fuel. However best to phone Sigg UK and ask them.

### ⭐⭐⭐⭐ Doesn't fit Chilly's bottles
*by N***H on 3 March 2024*

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.
