My 3/8" hose's that comes off the two Kasco 1/2hp air compressors is always hot to the touch. These two hoses are approx. 24" long before it ties into the larger 1.5" line. I just figured the hot air was coming from friction at or inside the pump. I wondered why they have a 3/8th " hose coming off the pump, I would have thought a larger hose would be bigger.
