tstormdiver,
As you stated your hose was found to be defective and from the sound of it due to a problem in the attachment of the fitting. If you read my statement that you quoted you will see it falls squarely into the category of a failure due to manufacturing problems. Secondly I would have to ask if you regularly slid the hose end protectors up to inspect for problem signs before each dive outing. Although it is common for failure to occur at the location of the fitting swage proper visual inspection will often find evidence of the impending failure. We use strain reliefs to lower the chances of this particular failure but unless we inspect our gear properly it is a likely spot to occur. However as statement you quoted does state "High Pressure hoses nearly never fail without first showing signs of problems." It does not rule out that it happens occasionally. Again under normal circumstances it will show signs prior to failure.
