A typical finding when researching greases for use with o-rings and seals: {link} There is an elastomer compatibility chart on page 7. It seems to me, a PFPE based grease is the best choice material for use on our espresso machines with silicone piston seals. Its operating temperatures far exceed our use, safe with silicone and

How bad is your reservoir? I have an extra one that seeps a little through some cracks and has a dribble through the working filter and valve.

My machine is also up and running. It arrived with couple of minor blemishes to the powder coat, but nothing like Matt's machine fortunately - certainly small enough that I won't bother ACS with them.
