Has anyone sourced aftermarket industrial hose that is resistant to the many solvents used for automatic roller rinse and cylinder scrubbers? After 20 years, our MAN ROLAND 300 pressure lines are so brittle that any attempt at repairing one leak creates several new leaks. At the moment, I'm looking for half-inch I.D. hose with a working pressure of not much more than 50 PSI. I have a feeling I should replace all of the hoses while I'm at it. All suggestions are appreciated.
