I'm having trouble locating small amounts of wire insulation. The few places I used to go were closing down. I don't want shrink wrap and am looking for standard rubber insulation. I considered cutting some rubber bicycle tubes, but I'm not sure they're still made of rubber.

Consider checking the heat shrink but opt for a replacement of the PSU if the wire insulation is breaking down.

You don't specify the wire type you're aiming to insulate, if it's below the SELV limit or running on AC mains, whether it's single core, multi-strand, coax, etc. Consider PTFE sleeving, which comes in various internal diameters. Smaller sizes work well with solid conductors, while larger ones may suit multi-strand wire more easily. You can purchase clear or colored sleeving. PTFE performs well up to 250C (superior to PVC).

Specifically, rubber? It works well unless you're dealing with extremely high voltages and currents.

Just want to
Thanks for your reply
I need to insulate 4, 120v 16 gauge wires and 8, 16 gauge, 24v 18.8 amp wires
The 8 24v 18.8amp wires are roughly 60cm each, 16 gauge. That’s double the size of a 30cm FAT PlayStation 2, so I need some extra length.
I connected a Mean Well SE-450-24
https://www.meanwell.com/Upload/PDF/SE-4...0-SPEC.PDF
It has the screw down wire terminals very easily without soldering.
I’m using the Mean Well SE-450-24 to run my HDPLEX HIFI DC-ATX 500 watt unit
I have two of these plugs for the 24v 18.8 amp

All of which are readily available by the roll, already properly insulated, and in the color/s of your choice. There's no need whatsoever to be reinventing the wheel as you seem so determined to do.

I'm careful about grouping 120V wires above the SELV limit with 24V wires below the SELV limit in the same cableform. This isn't sound engineering practice.
I would definitely avoid routing both 120V and 24V wires through the same connector—it's a risky approach. No certification from UL or CE would be achievable with such a setup. It's best to keep high and low voltages separate, or use double insulated cables.
If you're firm against using heatshrink, flexible braided Megamide is an option:

You can also opt for spiral binding:

Thanks for your reply. I wasn't planning to connect the 120v and 24v together; I was thinking they should stay separate. Would you know of a reliable mini fire extinguisher designed for PC electronics? It's something solid. I did my own wiring, and someone else installed my ATX power supply—remember we're all human and can make errors. I want to be safe. My regular fire extinguisher isn't suitable for electronics.
