Food safe lubrication is useful for keg parts and seals, but I also used it on my automatic coffee machine. Goes on easily, seals properly.
I had been begging beer for years and never knew such a thing existed until I was researching why/where I might be going through so much CO2. I am not sure it has made any difference yet, but the fact such a product exists, I am betting it is for a reason, so I will use it going forward in hopes of helping cut down how much CO2 I am going through.
Applies easy and doesn't have any crazy smell or anything. I'll definitely be using this each time I keg beer. Helped out with some tiny leaks I was tracking down too.
Does what it does. It's keg lube
