At least on my 220D the oil cooler is thermostatically regulated, so not just zero or full flow. Plus, at least with my hoses, the hose i.d. is greater than the feed into it, so there is a drop in pressure as soon as the oil passes this neck into the rubber portion; then the drop in pressure is much greater yet to the return hose as much pressure is lost in the oil radiator itself. "Oil Rated/Resistant" doesn't speak to the pressure rating, per se, unless it is written or provided on paper, but I think that the temperature of the oil in combination with the pressure is the true measure; i.e. It's burst pressure is much less with hot oil than cold oil and vice versa. Since Brian C has seen a ton of this stuff over the years and how they perform, just keep an eye on the metal crimp.
