PTFE,Polytetrafluoroethylene, has less surface friction than rubber, which means that flow can be improved by using PTFE hoses. While rubber is prone to break down at extreme temperatures, PTFE is highly temperature resistant, making it ideal for all kinds of automotive uses. most fuel or hydraulic hose shops will tell you the steel/hard lines will flow better because they have less friction loss than a rubber or PTFE line and the hard lines are less prone to deteriorate over time. the stainless braid helps keep the hose liner from expanding while also providing some mechanical protection.

Thanks for the information.
