Wow, 5 months! Of course if you had this hose in the caves that you were talking about, maybe that is all the longer you can expect to get!! Had a supplier tell me the worst thing you can do to this hose is drag it around!
I would think that a 3 wire hose would be rated higher than 4500 psi. We use a 2 wire 5800 psi hose. Has a 4-1 burst rating.
Our hose failures usually occur at the fittings (blow them out). Very rare do we blow the hose itself. I have been told that the high temperatures that we run is what causes most of the failures in all of our equipment, not just hoses.
I would be looking for a new supplier if my hoses only lasted 5 months.
