High Pressure Hoses
From our experience, we have found lots of cases of unexpected failures caused by using non-genuine hoses. We therefore decided to test genuine and non-genuine hoses to how they are different.
Genuine vs. Non-genuine
You can find lots of non-genuine hoses on the market, and they can fit our equipment - but do they have the 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.
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.
