Robinson mounts their oil coolers with rigid lines directly to the cooling
baffles/fan/scroll unit which in turn is mounted rigid to the engine. As far
as I remember there is no soft material anywhere in between, though there is
some delicate mounting of the oiler to do, so as not to put any torsion
and/or tension in the mounted cooler.
Generally this outlasts the 2200 hr TBO of the whole machine....
