This is a custom 3D-printed aftermarket pull-dump retention ring designed for compatibility with the Dive Rite Choptima rebreather.
The flexible, one-piece design allows the ring to stretch over the pull dump and seat cleanly at the junction where the counterlung meets the pull dump. No glue, clips, or fasteners are required.
I originally designed this part for my own unit after the upgraded pull dump did not seat as cleanly as I wanted. The ring helps improve the fit and finished appearance while maintaining enough flexibility for easy installation.
