There should be similar brass fittings with barbed end instead or compression fittings. I don't know how those are attached, but it threaded they will cut silicone hose, so the threads at least can not be used for mounting. If you use screw type hose clamps, get silicone syle clamps (from us boat? marine fittings) as the threads of auto hose clamps will also cut the silicone hose.
If the fittings are soldered on, sweat em off and the new ones on.
