This American company sells their equipment in France, looking thru their US website I see the pipes (page 8) are nominally inch but exact metric. i.e. the ½ inch is 16,5 mm, the 7/8 inch is 25 mm, etc. Most of the document does not list other SI units, they obviously assume everyone knows what Fahrenheit and inches of mercury are. I did email them asking to include SI but no reply. I’m aware the inch sizes do not correspond to the actual size, I’m not sure why?

They appear to have a very good product but have a hard time selling it from my difficulty in getting information. I’m interested in using this piping to install compressed air outlets in my workshop and garage, aka a barn over here which is 25 m long. Mike Payne
