regarding the silvia "conversion"
how about the stainless steel braided like on the 09 models?
is an improment from the teflon compression line
and yet is easy to work with when you have to remove or do repair on the unit

Most plumbing connections on Italian espresso machines are British Standard Pipe (BSP) sizes.  They are actually specified in inches but the number of threads per inch don't match American pipe specs.  McMaster Carr has a wide selection of adapters and fittings, plus they are very easy to order from.

If you can send me a picture of the existing fittings you want to mate to I may have some extra stuff laying around.  I probabl could not bend he tube exactly but could send yo some of the fittings for maybe a 1/4" Copper tube and you could braze them on or something.

Friends,

The original post was from almost 5 years ago.  I hope that roasted_been has managed to solve it by now.

You can buy tubing and fitting at McMaster.com
http://www.mcmaster.com/#copper-tubing/=6x1mov

Click on metric and buy a tubing bender, kind of looks like pliers dont get a bending spring as its for larger bends not sharp angles and buy some extra tubing and a tubing cutter.....

All these tools and supplies will be less than the custom tubes I bet...

2005 I guess I should read through before posting next time :)

Reviving this thread yet again:

I'm doing a minor overhaul on an older Mininova and wanting to replace many of the smaller teflon and copper tubing (mostly metric 6mm). Most of the fittings are Serto brass and I have managed to find a source in the states (Maryland metrics) for the nuts and ferrules (very specific to the fittings that are present), that I need.

I am also able to order metric 6mm (bendable) copper tubing but the minimum order seems to be 10m! I only need at most .5m. I have searched and followed up on all the suggestions in older threads and followed up on any Google suggestions that appeared likely and haven't found any good alternatives.

Does anyone have any suggestions that they are sure of for suppliers that might handle 6mm copper tubing in smaller amounts and/or in Canada? If I go ahead and order 10m does anyone have any interest in purchasing part of 10m at a reasonable price?

Let me know. Thanks in advance. Conrad

Use fractional copper and ferrules and the old nuts if usable.

The nuts themselves are not metric, but BPPT and we have them.  You can usually ream them out to fit the US fractional copper.

You could also use Teflon for everything except the hot water and the group, using push-on connectors.

You don't usually have to replace copper lines, just clean and perhaps re-ferrule the ends.
