Yes, we had this problem for Ultimate Ascent (our climber was primarily pneumatically powered). We had several hoses aneurism and rupture at the compressor output. By the time we got to the hose, the outrushing air had cooled the hose, so it took us several times (and changing hose batches) before we figured out that the heat was softening the tubing.

As hinted above, the key is dissipating that heat before reaching the first rubber tubing. In our case, we simply moved the pressure switch, stored pressure gauge, and vent plug onto an all-brass "christmas tree" leading away from the compressor, and put the first fitting to rubber tubing at the far end of all this brass. If this hadn't been enough, we probably would have heat-sinked this mass of metal to radiator fins or the robot chassis, and only then gone to a more active (fan) cooling mechanism.
