Spare Parts

Thermosonline are the only retailer of genuine Thermos parts in the UK and offer as many spare parts as possible. 
But 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. 
If you cannot see your flask on our website regretfully it is unlikely we have the stopper.
