Cracking under pressure is one of the signs that someone or something is not fit for the job since the job is expected to live in the world of pressure. Such is the plight of hydraulic hoses used for mining, construction, transportation, steel mill and others. Oil or gas is usually moved from one tank to another. Since there is pressure, assurance that the hose will hold well to its form is a prime consideration when choosing hydraulic hose manufacturers because a crack can cost lives and loss of the business. Go with those which have been tried, not just once, but several times.
