    oil cooler lines

    I would like to replace my (seeping) oil cooler lines with braided stainless line. I am familiar with how to use the fittings on US standard sied tubings, however the oil cooler lines are metric (.600 inch OD), which would be CLOSE to a -10 A/N (approx 5/8 inch)

    Has anyone successfully replaced the rubber section of the hose with braided stainless, or conversely have you replaced the whole line (oring fitting to oring fitting) with off the shelf fittings, without too much trouble?

    I DO NOT want to have to weld new fittings into the adapter or replace the stock cooler (im lazy and cheap)

    If any of you racers out there have done this for compliance, please share your sizes that you used for this

    The only race cars that I know of with SS lines for the oil cooler are using a cooler with A/N fittings. On the engine side they used parts of the OE hoses silver soldered to A/N fittings or replaced the oil filter housing with one that would accept A/N fittings.

    The OE lines aren't a bad solution. A hose shop can rebuild them with new hoses and they'll be good for another 20 years.

      Any problems that you know of with the silver solder failing under heat cycle? If I can source steel weld-in type fittings (fairly easy) would brazing be a better method of joining the end to the tubing?



      I can adapt the ends here in house to fit the tubing (and then silver solder). I have trust issues with farming out work, so I prefer to do things myself (been screwed too many times)

        Cadmium bearing silver solder is more than adequate for this. The tensile strength of a correctly made joint should in in the 80-100Ksi range and the temperatures encountered won't be a problem.
