Distinct hydraulic hose collection and measurements Possess a SAE-needed minimum amount bend radius specification. This only implies that flexing the hose lower than the required minimal bend radius can drastically improve the probabilities on the hose failing and minimizes the hose everyday living cycle.
In specialized industries, such as pile driving, drilling, oil and mining, there are occasions when hoses are Utilized in techniques they are not designed or rated.
