These are the \" T \" fittings used to splice the auxiliary hoses into the original lines. Because I had to replace the original lines and it was more economical to have new hoses made commercially the clamps shown in these pictures were only used to attach the new hose and not the fittings in the old hose. I bought these fittings and clamps at O\'Reilly Auto Parts. Later when I found I needed to have new hoses made I also found I could get the clamps and fittings at the air-condition supply house for about half the price they were at the auto store. The black rubber pads with screws coming out of both ends hold the condenser in the condenser frame in front of the radiator. I have spent numerious hours looking for these. I have not found an auto parts house that stocks them. I found these available at Grainger industrial and commercial equipment and supplies. They are listed as rubber mounts for motor noise reduction. part # 3CC03
