Screw through radiant pipe. Anyone know what it is?

[Ddiego868]

Client has getting new hardwood floor and contractor put screw through pipe. I was able to isolate zone so it is not leaking anymore. I have gone to multiple plumbing supply stores asking what this is but no one knows. Anyone know what brand pipe this is. It seems to be 3/8 I’m not sure. Is it two pipes I believe a supply and return but I’m not too familiar with radiant. I’m attaching some pictures. Also it already has a coupling which is what I’m trying find! It seems to have a weird style clamp. Would appreciate some help with this thanks for taking the time to read through.

Have a pic of the fitting? Any symbols or letters on it? Hardwood floor with radiate heat normally has a top temperature range of 85° water but need to check with the manufacturer of floor for their recommendation. Cut a section out of it for a accurate size. Tubing doesn't have to be potable, radiate systems are not high pressure 10-12 lbs max and water temp isn't high..

Take a section of tube into the store and find a barb or pex fitting that'll fit tight.
