With the stuff I listed earlier, if there's hose damage you can replace it without even removing the fittings from the tube or cooler. If the cooler gets damaged you can even bypass it with just a spare length of hose, which you may carry anyway and 2 female fittings to adapt each end.
Southcott hydraulics have the steel fittings, hose and push lok hose ends. Motorsport connections have the alloy fittings. The alloy ends size by the weld end, it's tapered and the right one fits over the cooler pipe perfectly. I'll try to find the receipts for part numbers.
