The packaging envelopes of the modern racing car become tighter each year – leaving less room for auxiliaries such as plumbing. At the same time it becomes more and more difficult to get the cars down to minimum weight. Earl's ultra-fle 650(TM) hose solves these issues. Earl's finest and lightest hose combines a woven ultra–light Kevlar TM) braid with a smooth bore Teflon(R) tubing for increased flow and convoluted outside for incredible flexibility. It also has significantly higher flow and pressure ratings than conventional convoluted Teflon hose. Ultra-flex 650(TM) is 60 percent lighter than our stainless braid–protected synthetic rubber hose, and 15 percent lighter than our pro-lite 350(TM) hose. You have spent a lot of time, energy and money on your race engine and you should bring the life sustaining fluid to it with the best hose on the market today – Earl's ultra-flex 650(TM) .
