A replacement for the HP-41 zebra connector

So...

Silicone tubing seems to be what most think to be a good choice.

Amazon in Germany seems to be a simple source for tubes of different measures, e.g.

https://www.amazon.de/gp/aw/d/B00K5TQG1I...1evynPOAcL

where 1x2mm means 1mm inner and 2mm outer diameter.

Question to those who tried: What size would you go for in terms of total, compacted silicone thickness? Is 2 mm enough or should one look to 4, 5mm even?

Thanks!
