Just wanted to add alittle observation here on this thread. The overheating of the compresssor outlet hose is caused by high pressure during pumping process. The compressor is basically a pump that creates flow, the pressure comes from the resultant of the restriction e.g: the existing tire pressure, nipple orifice and hose inside diameter. I noticed that when I inflate 4 tires at the same time (with my Vitaly Compressor 2 pistons) with 8mm ID hose, the head pressure during pumping is only around 2 to 5 psi above the system pressure. Maximum 38psi when the system pressure is 35psi. The temperature of the compressor outlet hose was never getting very hot.
On the other side when I inflate only 1 tire at a time, the head pressure during pumping can reach 60 psi and the outlet hose was very very hot.
So normally I inflate 4 tires at the same time for a quicker turn around time and much less heat on the hose. This cheaper compressor that I used is still good and strong with it's orginal outlet hose for almost 3 years now.
