Installed in my Palazzo RV. Compression fittings for air ducts. The kit contained only a fitting connected to the solenoid. Luckily I had the air line and compression fitting from the boat's air brake on hand. Although I knew what I was looking for, I could not find a compression fit exactly like the one that came with the horn. Here's what works for connecting an air line to your air supply system. Look for 47205. Order part number 47205.04.02, 47205.04.04, 47205.04.06 or 47205.04.08 depending on the size of the air supply line. You will also need a compression insert, for example: 1/4" tube OD x 5/32" hose ID. It goes at the end of the catenary. Much luck
