5 Reasons Hose Fail

Did you know that most TFE-lined hose failures are due to factors that can be controlled? By avoiding one or all of these pitfalls you can maximize the life of your hose.

Right Hose, Wrong Application

Hoses generally fail within a few inches of the end connections. Choosing quality, proper end connections and design- ing a suitable layout should eliminate a high percentage of failures. Keep in mind: pressure surges that challenge the rated working pressure, avoiding applications with pressure surges, or temperatures that exceed the rated limits should all be considered when selecting the proper hose for the application.

Right Application, Wrong Hose

TFE is one of the most chemically inert and compatible materials on Earth. However, use of rubber, metal or even TFE-wetted parts in the wrong service can be prevented by checking fluid compatibility with wetted hose materials be- fore installation. TFE-lined hoses are permeable and mostly unable to achieve more than moderate vacuum service in light gas service.

External Damage

Abrasion can occur from a poorly routed hose and will neg- atively affect the stainless steel outer braid of TFE-lined hoses. This drastically reduces the pressure containing capabilities. Consider the least hazardous path for your hose and make use of protective jackets or spring guards.

Electrostatic Discharge

TFE is not a good conductor of electricity. Flow of electricity can be impeded when fluids that are good conductors, like steam or fuels, come in contact with each other. Static electricity can be generated by fluid passing through the hose. Although TFE is non- conductive it can be modified with sufficient conductivity to ground the static electric charge. Eliminating a risk of catastrophic failure from charged particles arcing through the TFE core.

Tested Hose Works Better

Poor quality components, or choosing a hose solely on low bid can lead to high costs associated with maintenance, safety, lost fluid or compromised equipment. You should expect a purchased product to work well. If there is any doubt, take advantage of manufacturer's technical support. Choose your hose wisely!!
