Breakaway whip hoses allow the breakaway to pull apart correctly. Goodyear Flexsteel whip hoses are constructed of a single braid of high tensile wire for strength and static conductivity.  All Goodyear hoses are UL listed, factory coupled and tested with the new lighter, stronger Fuel Grip coupling. All 5/8" and 3/4" whip hoses have 3/4" NPT male ends. The 1" has 1" NPT male ends. Chrome ends are available.
