    Under dash AC leaking fitting

    Had trouble with the flare fitting leaking on my under dash ac unit, only flare fitting left on the car was on  the low side of the evaporator, found some cone shaped washers on ebay put 1 on, and it fixed the problem.

    Just FYI, a flat copper washer accomplishes the same thing, becoming conical as the fitting is tightened, in case you can't find a pre-shaped one.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.
