Earl's Teflon/braided stainless STEEL BRAKE lines are DOT approved.
http://www.earlsperformance.com/html/index.htm I'd be surprised if Aeroquip Teflon/Stainless lines were not DOT approved, as they are pretty much the pioneer of braided SS hose, although primarily for the aircraft industry.
Make sure you only use the braided SS hose w/ Teflon liner for brake lines as the rubber lined is not suitable for brakes. But great for fuel lines tho.
