High Pressure Hoses
You can find lots of non-genuine hoses on the market, and they can fit our equipment - but do they the have same specifications as genuine hoses? The answer is: No. From our experience, we have found many cases of unexpected failures caused by using non-genuine hoses. We therefore decided to test genuine and non-genuine hoses to see how they are different.
Genuine vs. Non-Genuine
The following are test results between genuine hoses and non-genuine hoses. For best results, Hitachi recommends that you use genuine hoses.
Minimum Burst Pressure
Non-genuine hose breaking pressure is 40% to 50% lower than genuine hoses. Genuine hose breaking phenomenon consisted of just oil leakage, while non-genuine hoses, had not only leakage but in some cases broken fittings, and disconnected fittings.
Fitting is broken
Hose is disconnected
Tension till Broken
Non-genuine hoses break at 25% to 60% lower tension than genuine hoses.
Impulse Test
Non-genuine hoses start leaking and/or are broken at an 80% to 90% lower cycle than genuine hoses.
Fitting pipe is broken
Fitting pipe is broken
Hitachi hoses must meet our strict specifications, but from test results, non-genuine hoses specifications are lower than Hitachi hoses. Hitachi would like to recommend that you use only genuine Hitachi hoses. This will reduce your total maintenance cost (less replacement), and also prevent injury, machine damage and environmental pollution.
