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.

Sigg replacement seals
Impossible to get old seal off so couldn't use them. Very expensive so sent back. It was cheaper to buy a whe new screw top

Doesn't fit Chilly's bottles
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.

Good for KBT and old tops
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

Revitalised my old Sigg water bottles
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.

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

Doesn’t fit chillys bottle
Fits on lid but are too wide for the lid to fit back in the bottle. Bought for chillys bottle as it states it will fit and it doesn’t. So no good.

Adapté pour la gourde Qeshua
Correspond tout à fait au format nécessaire pour ma gourde Queshua. J’ai perdu le joint initial en la nettoyant et sans joint concrètement la froide est inutilisable donc oui mieux vaut acheter un joint 🤭 Et pour le coup il y en a 2 donc si jamais ça arrive de nouveau j’en aurais un de rechange. Je recommande !

Excellent fit for 0.6l Sigg aluminum bottle caps
I own six Sigg aluminum bottles (0.6l & 1.0l) and have had to replace the gaskets over the 40 year life of the bottles & caps. These gaskets are the PERFECT fit! 👍👍‼️

OTTIMO PRODOTTO
La borraccia perdeva e con questa guarnizione abbiamo risolto il problema senza dover per forza buttare la borraccia. Nella confezione ce ne sono due e la cosa è molto gradita nel caso la prima si consumi o si perda.
