I am replacing the thermistor on my e3d v6 hot end and I don't

I am replacing the thermistor on my e3d v6 hot end and I don’t have enough fiberglass sleeving from the original to reuse. I have a new thermistor, but no insulating sleeving. Is there something I can buy locally or buy in the US online that would work? I just don’t want to wait the week or so to receive an order from e3d. http://e3d-online.com/FibreGlass-Sleeving?search=thermistor

They sell the E3D sleeving in the US.

Thanks, I will order some from them today.
