Hello:
This is my first post here and I hope it can be useful.
I think you are looking for the fiberglass tape usually found at the CRJ connectors to avoid chaffing the wires with the backshell.
If that is the case, you can use 3M 69 tape or any other brand that meets the MIL-I-19166 standard. The permacell for P/N for this standard is 212.
P.S. I've done my best with my english.
