Problem: Hose has burst.  Rusted wire, torn, and rotted fibers are present.  This was caused by abrasion damage.  Exposure to elements will accelerate the deterioration.

Solution: Route the hose so it does not rub against other objects while under pressure.  Suggest using clamps and spring guards to protect.


Problem: Hose has burst on outside bend of hose.  This hose has been bent past minimum bend radius.  It has also taken a set in a bent position due to a kink in the inner tube or reinforcement.

Solution: Check minimum bend radius for hose.  Utilize bend tube elbows if possible.


Problem: Excessive heat.  Hose cover or inner tube is brittle and cracked and is not flexible at room temperature.

Solution: Use hose with higher temperature rating or protect from heat with shields.  Examine entire system for potential heat source.  For example undersized lines, excessively long lines, too many bends and/or fitting, reservoir low on fuel.


Problem: Incompatible fluid.  Portions of the inner tube are swollen and/or washed out.  Cover may also be swollen.

Solution: Make sure hose used is compatible with fluid being used. 


Problem: Hose cover blistered and pulling away from carcass.  Gas has effused through the tube and become trapped under the cover. 

Solution: Use perforated, pin-pricked, or fiber cover.


Problem: Hose has burst cleanly with no random wire breakage and cover abrasion.  This condition is caused by excessive pressure.

Solution: Use hose with higher pressure rating.  Check pressure relief for damage or improper seating.


Problem: Hose has burst.  Hose is permanently twisted and kinked.  Many broken wires in failure area.

Solution: Hose twisting can reduce hose life by 90%.  Tighten ends properly.  Reroute hose to eliminate twist.  Route hose to flex in only one plane.  Use hose layline for a guide.

Warning - Selection of Hose: Selection of the proper hose for the application is essential to the proper operation and safe use of the hose and related equipment.  Inadequate attention to selection of hose for application can result in serious bodily injury or property damage.  In order to avoid serious bodily injury or proprty damage resulting from selection of the wong hose, you should carefully review how you will be using the hydraulic hose.  Hose failures can be caused by conditions such as excessive pressures, fluid incmpatibility, extreme temperatures, and many more environmental factors.  The failures listed are the common failures seen in hydraulic hose applications.
