247's 250 series hose has a PTFE inner liner and is reinforced with an S/S middle layer offering the same performance as the 200 series hose. The 3 layer Black Nylon braid offers both cosmetic and abrasion resistance. The PTFE inner liner not only offers a greater operating and burst pressure but does not permeate like rubber hoses making it the perfect choice for exotic blends of fuels and emission controlled cars. * Suitable for brake, power steering, nitrous, vacuum, pressure, fuel and hydraulic applications. * Min temp -70 to 250 deg
