Rod, thanks for replying. However, it’s not the rubber part of the hose that is the problem. It will not seat properly into the compressor. There is a bracket that presses both hoses into place with a bolt in the middle. The bracket is permanently attached to one of the hoses but is open on one end to allow the other hose to be secured. The technician put a new O-ring in place but that did not help. The fitting still leaks. I suggested welding the fitting in place but he said the heat may damage the compressor. Looks like I need to get a new (or used) hose that has the bracket attached to it.
