Thermosonline are the only retailer of genuine Thermos parts in the UK and offer as many spare parts as possible.
Due to their fragile nature Thermos do not supply replacement glass liners.
Each flask has a unique stopper and cup so please check carefully before ordering.
Thermos do not sell any replacement seals for any of their items, only the complete stopper
If you cannot see your spare on our website please email Thermos UK email@example.com
