CST has obviously changed the teflon sheathing. I just installed a DEPS in my new plane using a set from CST that I had purchased a couple of years ago.
The sheathing was a white color , straight in the package ( not coiled up) and what I received when I reordered, to have more on hand for the future, is transparent and came coiled like you guys are saying.
I didn't check the ID but the new stuff's OD is defiitely thinner than the old.
