It is food grade silicone. I have never thought about what could be a replacement, has to be food grade and be able to hold up to the acidity of the content.Does it not matter what sort of rubber the O ring is made from though?
It's true that they can be a bit fiddly and when something goes wrong it can be a bit of a head scratcher but I'd never go back to bottling unless I had to. I tailor my recipes so that I don't even have any leftover beer for the odd bottle. And I recently off-loaded about 70 grolsch bottles as they were just gathering dust.I thought Corny Kegs were the bees knees of the keg world,V the leaky King Kegs
Shows i was wise to start collecting beer bottles for brewday 2020
Trouble is I am moving home soon so have to pack all those blasted bottles.!!
