That is NOT a DOT-approved line in your link. Read carefully, what blunt is selling is the same type of thing just a little less deceptive in its marketing.
Here's their wording, tricky and not officially dot-approved. Note that it doesn't actually say DOT-approved.
"it is also designed to meet the Department of Transportation Motor Vehicle Standard MVSS-106."
Without going into it, the clutch line does not go through the same DOT guidelines as a brake line. It's just a nice touch to use dot-line (though its not officially dot-approved).
