content: Hi Quarks,Do you need the part or the color?I have a HP power supply with crazy color coding scheme on the binding posts - Mr. Edding fixed it quickly.You can use candle wax to mask zones where no color shall be.

content: thanks for the reply.Mabe to make it more clear, I only need the red ring as an original part for HP/Agilent binding posts.If anyone knows how to remove that ring from another HP post without damaging it (so I can use it on my post), please share.

content: I know it's not what you want, but just for the record I checked at Agilent not too long ago and the binding posts were still available as a replacement parts. Unfortunately a set of 3 (red/black/green) would cost around $50.I wish Radio Shack (or anybody actually) had those with the green ring also.

content: Hi quarks,I have binding posts from a 6236B power supply. Maybe the red ring will fit. It has 9.5mm outer and 6.2mm inner diameter. How many do you need?

content: I've had the same problem - tip ring lost from HP banana posts. Fortunately I had a scrapped bit of HP gear with the same posts.It occurs to me that this is a perfect use for a 3D printer, if you could find filament of the right colors.Those HP terminal post tips often break or come loose and get lost. Someone with a 3D printer could make them? If the surface finish was close enough, they'd sell. And they are small and don't use much material.

content: @sync, many thanks for your reply and the binding posts you will send.@TerraHertz, thanks for your reply.Have you managed to change the tip ring?If yes, could you please give a hint how to pull out a ring without damaging it.

content: Quote from: quarks on January 12, 2015, 07:51:17 amHmm, it's embarrassing but I can't recall the details. Was years ago. I think I replaced the whole post. I do recall they are glued in, and I guess on some they didn't use enough glue.

content: short updatetoday I received sacrificial binding posts from sync and tried several methods to get the red ring out without effect.Finally I had to cut it out. It seems to be either glued or ultra-sonic welded into the gray plastic (see pic.).Now I wonder even more how this ring could come off my DMM and get lost in the first place.Anyhow thanks to sync I managed to replace the lost ring.Thanks again to anyone for the support.byequarks
