I'm trying to find something I saw a while ago. It's a plastic cover for made from plastic, I want it to fit on a piece of 5mm rod. I think it was like heat shrink tubing but with a solid end. Black with a shiny finish.

Any ideas?!

You can get heat shrink and cold shrink end caps for sealing cable ends but I'm guessing you want something a little thicker and ordinary ferrules should fit the bill either a tight stretch fit or a dab of adhesive. **LINK**

it sounds more like a plastic coating melted on.

it comes as a powder and you heat the metal and dip it in the powder.

I cant remember the name offhand but try google for plastic coating .

I,ll look tomorrow, I'm too tired now.

PVC end caps are readily available but whether they will be suitable will depend on how long your need to be.

I have used PVC caps that look just like the ones in this link. I collected them ages ago as they were supplied as dust caps on some pneumatic components. They were a snug fit on 5mm rod and about 15mm long.

Perhaps it was a plastic dip you have seen. The link shows a DIY solution from Frost Automotive Restoration.

Or, depending on your application, you could make end caps from Sugru and cover the length with heatshrink?

It's quite hard to get a good finish with Sugru, much patience and a wet finger was needed to do THIS repair.

I think it would work well if you can find a way to mould it, any suggestions for a release agent?

There is an adhesive heat shrink tubing which i use regularly for making plugs waterproof. This will seal at the ends though you will not get a rounded seal.

There are lots of these sort of caps used in industry for a particular product initially that then get used elsewhere. For example the RF connectors in cable TV street cabinets have plastic caps when new which fit a 10mm rod. The SMA type of RF connector used in other equipment used one for1/4 inch.. SMB connectors will be smaller at 3mm. I used to bin loads of them.
So you need to thnk of a mass produced component that is 5mm and needs a protective cap. Then find who is using them and chucking away the end caps. I can only think of knitting needles .
