for Original Isosteel ONLY! Don't use for Any Other Brand! Replacement Quickstop Lid VA-Q9551 for Isosteel Vacuum Flask only! VA-9551Q 17 fl. oz, VA-9552Q 25 fl. oz. and VA-9553Q/VA-9562DQ 34 fl. oz.

I have been using the Isosteel thermos for 5 years,Great design for someone that has some disability or hand dexterity. One hand operation;Just press the button and pour your coffee or tea.

Appreciate they sell these replacement parts. We enjoy our thermos and use often enough to eventually wear out pour spout. My husband likes but disappointed how quickly they start leaking

Haven't fitted it, just bought it for back up, but seems it will be as it is an exact replica of the original fitting I have.

Good replacement
