## 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.

## Features

- For kids' bottles: The rubber seal in a set of 2 is suitable for use with the KBT screw top from SIGG, and ensures that the bottle remains reliably leak-proof.
- Spare part: The SIGG bottles are so long-lasting that the rubber gasket may need replacement more quickly than the bottle itself. Replacement is quick and easy.
- Leak-proof cap: Thanks to this practical and easily replaced rubber seal, the bottle cap of any KBT thermos flask can quickly be made leak-proof again.
- Safe drinking: The rubber seal replacement for SIGG bottles is entirely BPA-free and does not contain pollutants such as oestrogenic substances or phthalates.
- Delivery & details : SIGG bottle seal for KBT top, leak-proof bottle cap gasket, dishwasher-safe, pollutant- and BPA-free, Swiss design, item number: 7815.31

## 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.
