I have 13 Genies running and have been refilling cartridges for a couple of years. The silicone needle ports on my 40-odd cartridges are wearing out so they all leak, and I am searching for a source of these little gizmos. I have advertised on eBay, Freecycle, Craig's List, etc for empty cartridges, but have never gotten any from anyone. Does anyone know where to get these things? I can't believe that Petnovations had these things custom-designed for Genie cartridges; they must be some kind of standard part, but I can't find them anywhere on any of the medical or lab supply sites.
If anyone knows where to get these, or would just like to get rid of a pile of empty cartridges, please post a reply or email me.
Thanks
Justin Harlow
