My understanding is that the green bearings have their own seals built in.
I would still lightly RTV where they seat to the tube.
I have read where the inner seals can be put in for extra leak protection but not mandatory either way.
Well I tried to install the new seals my largest socket is a 36 which was a little small and bent the seal so that's a no go for me. I'm going to put it all in without a seal (unless I manically find one before I get it all hooked up and hope for no leaks.
On a side note a Copenhagen can is the perfect size to out them in but it is to flimsy to actually get the job done .
