HO Diaphragm for 1 Rivarossi and Other Heavyweight Cars. Black only. Close the gap with our innovative injection molded operating diaphragms. This easy to assemble kit turns a string of passenger cars into a train. Diaphragms stay connected in turn radii over 24 inches and have no minimum radius for smooth operation. Diaphragms are designed for Kadee #5, Intermountain and McHenry couplers unless otherwise noted. Instructions are included with all kits.

    First time I use these. Quite satisfied with the final result. More detailed instructions would help.

    Great diaphragms

    I have used these diaphragms for years and bought these to replace units that were used up. I have them on all my passenger cars and they always work great. The diaphragms for the lightweight cars work well also.
