Anybody heard of using copper water pipe as hydraulic line?

A drawbar-only Farmall 560 I just bought uses standard copper water pipes to extend two steel hydraulic lines that run from the hydraulic valve complex to just in front of the seat mounting box. The copper lines run rearward to a block that has two standard hydraulic line connectors for attaching implements. The copper lines are connected by standard plumbers compression fittings to the steel lines. Under load (lifting a big disk harrow)one of the steel lines keeps busting away from the compression fitting because the whole line (steel + copper) is able to flex just enough sideways to pull the steel pipe out of the compression ring. The neighbor I bought the tractor from says he was thinking about going to flexible hydraulic lines to extend the steel lines. I don't feel very comfortable running copper pipe on a 1500 psi or so hydraulic system but maybe I'm wrong. Anyone else using copper? If I go to steel pipe are there steel compression fittings? Would flexible line be the answer? Should I try to stablize the line laterally? Thanks.
