It's always better to pick the correct hose for the application. A hose for an oil catch can should have good temperature resistance and be able to handle petroleum products versus say a water and antifreeze solution.
My feeling is the psi (pressure) is not very important. If you look at the way MINI attaches the stock hose to the fitting on the valve cover (R56), it's just a push on with a decorative plastic clip. The OEM hose is not even reinforced. The nice thing about McMaster-Carr is the additional information they supply with their product. I don't know what diameter hose you need, but notice they give you the bend radius (indication of how tight a bend you can make). Look at the temperature range and stick with a grade designed for petroleum-based oils. The other nice thing about this company; they can custom make the hoses to your length and add special hose fittings for a cleaner installation vs say the standard method of using hose screw clamps.
