can I tighten a 3/4" compression coupling onto a 22 mm pipe, without it leaking? it is just a little smaller than 3/4". Bob

conversion fittings?

I had the same idea. I am looking into using a european boiler in canada (i'm checking into regulatory issues). The boiler has 22mm fittings.

Shouldn't someone make conversion fittings for metric to imperial piping?

solar panels from the U.K.

are what I'm hooking up. I can't buy any conversion fittings from the local suppliers or the solar panel mfgr. The panel manufacturer told me to tighten the 3/4" down on the 22 mm pipe. or to use the 22 mm fittings supplied with the panels and sand down the 3/4" copper till it fits into the 22 mm compression fittings. with the anti-freeze in the system I am worried about leaks.

I think I would use the 22 mm fitting's supplied and shave down the copper. If you use L-copper you shouldn't run into any issue with to thin a wall. I would just be concerned with trying to crank a 3/4 fitting on there...worried it would strip...just my 2 cent's..:)
