Silicon washer is flat washer shape.
The silicon seal inside the cap is thin flat washer shape. I doubt this will seal very well for anyone that is applying vacuum to their apparatus.I will be replacing this with an o-ring that I'll have to measure, source and purchase. It is likely with a proper o-ring it will seal against a thermometer or probe tightly enough to preserve vacuum level.Otherwise price was very affordable... Especially considering the next day delivery.
