This auction is for 1 pair of tube diaphragms. If you have 10 cars you are replacing the diaphragms, then you will want to buy a quantity of 10.

Look at the pictures, one picture shows the gap between the cars with the standard Walthers Draw Bars. The other photo shows the gap with the cars on a 26" radius corner.

There are a couple of pictures that show the tube diaphragms next to the Walthers plate diaphragms. I replaced diaphragms on Proto, City Series, and Ready to Run cars with no issues.

The Dome and baggage cars I had to install the long drawbars to get the cars to couple together.

You must use Super Glue (Cyanoacrylate Glue) to attach the tube diaphragms.
