Can anybody tell me if this lube is good for lever pistons? I know Saeco uses it for their brew chambers
Thx

I use Dow Corning Molykote 111. According to the Safety Data Sheet, it meets NSF 51 for food equipment materials, NSF 61 for drinking water system components, and FDA 21 CFR 175.300 for food contact.

According to the Safety Data Sheet for Haynes Lubri-Film, it meets NSF H1 for incidental food contact.

The data sheet says the melting point is 200f, so I would say it's not good for this application. Get the molykote 111, big tube cheap and last a really long time.

conti lever rebuild question

I use Dow Corning Molykote 111. I got this little container the diameter of a silver dollar and something like an inch high for like $2 on amazon. I just put a dab on a clean toothpick to apply. It works great and will last me forever.

The only thing to look out for is that I don't think that all of it will necessarily come out with the chemical cleaning. I'll use a gentle cloth to clean the cam shaft and the pins, and I always get a few small spots of some black stuff to come off. My guess is that the lube stores some of the buildup, and the chemical backflush doesn't clean it all out. But it's easy to wipe off, so it adds only a few seconds to my chemical backflush/lubrication routine.

No, the Hayne's Lubri-Film is a petroleum based lube & shouldn't be used on rubber seals. Save it for grinder threads, ect & use a food safe silicone based lube (Molykote 111) on the piston seals.

While working in the industrial food industry we used a product called Petrol Gel on o rings and seals which was rated for food contact, I seem to recall it was usable to 200 degrees F but may be mistaken. It is an excellent product with no taste and slippery as all get out.

Petro-Gel operating temp range is 0*-185*F. A little low for espresso machine use. The Molykote 111 range is -40*C - 200*C.

Avoid the molybdenium disulfide free version which is clear in a green tube with white lettering, some are still floating around.

Make sure you get the Dow Molykote 111.
