Use the proper "Live Length". Live length is the measurement of the actual flexible portion of the hose assembly. Different fittings differ in length, which affects the Live Length in relation to the overall length of the assembly. Live length is an important aspect of hose specification particularly in hose installations which require a sharp degree of bend or repetitive flexing. Never attempt to stretch or compress a hose assembly.
Avoid abrasion. External abrasion or constant rubbing will damage the braid reinforcement thereby weakening the hoses very pressure retention. Hose assemblies with visibly damaged braid, including broken wire, should be replaced immediately! If your installation requires a degree of abrasion (e.g. confined space, dragging on the floor) we recommend an external protective cover of PVC, rubber or Armor Casing.
Hose storage. Proper storage adds significantly to the life of a hose assembly. The assembly should be properly supported so that it never exceeds bend radius. Hoses should not be stored in areas of possible corrosion attack or chemical spills. There should never be anything placed on top of a hose assembly, while in storage or in use. See our hose storage solutions.
Never use the hose assembly to support weight. The hose assembly should never be used to support the weight of valves or piping. Pipe should be properly supported with anchors.
Clean hose assemblies after each use. Flushing and rinsing hose assemblies after each use goes a long way towards a long hose life. Proper cleaning removes corrosive materials and residual product which can attack the hose inner core.
Never torque a hose assembly. Hose assemblies are not designed to withstand twisting or torsional forces. Torque can occur upon installation or when the hose is in use, through out of plane flexing. When installing a metal hose, always use two wrenches, one to hold the hose to prevent it from twisting and the other to tighten the fitting. Always make sure that movement remains in the same plane as hose installation. (see chart for examples) Always use the proper hose length. Hose assemblies that are measured short can exceed bend radius causing stress and premature failure. If a bend is too sharp, use elbows.
