Why do some coil hoses not last, rebound well or tangle easily?
It starts with using the right materials such as polyether-based polyurethane, and not polyester-based polyurethane. Polyether-based polyurethanes are the only ones designed for water applications. Polyester-based polyurethanes, on the other hand, are not. Polyester-based polyurethanes get attacked quickly by water which leads to tubing hydrolysis creating a coil hose that gets brittle and cracks. You also have to use enough material in your hose in manufacturing. We use over 4 pounds of polyurethane per 75 ft coil hose vs 2-3 pounds often found in others. This gives your coil hose what we call “coil hose integrity.” It is much less prone to tangle, it rebounds very well, the coil maintains it’s shape and does not “grow” in diameter and become loose and sloppy after you stretch it. We also put our coil hose through two additional steps in the manufacturing process. We “cure” our coils creating better “thermoset” properties which provide much better coil memory. We also “reverse” our co
