Really? The black stuff seems to have qualities very different from the other hdpe... Too different to just be the thickness? For example if I whitle them the gas pipe (+3m) is softer whereas the black pipe is more brittle.
I'm not saying the black pipe is ultra high density, but it's a higher density than the gas pipe I have.
