Especially when you've got a cab jacked up to replace a hose you can barely reach, let alone get a pick in there to pop the old o-ring out.IMHO give them a swerve. My pet hate is any 0 ring fittings.
Flare-Tite are a similar style sleeve that fits over the male end. I don't need to repair a leak, I just noticed these fittings when I took the articulation valve off the grader. There must be a reason they are used instead of standard JIC fittings?Here's another option for leaking JIC fittings, work pretty good if fitting is not too damaged:

Sorry there isn't any picture for them, but they are thin copper gaskets that fit over the tapered end of fitting where the dimension "A" is shown. Won't seal a badly damaged fitting but work good for ones that just seem to seep.
