Fiberglass Insulation (Expandable, Rubber Coated)

Suitable for both the V4 and V3b Hot Ends, this insulation is used to maintain your hot end's temperature and to prevent potential burn injuries. 

*For all individually-sold fiberglass insulation pieces, you'll need to cut the insulation in order to match the size and dimensions of your specific Hot End. Insulation sold with Hot Ends are pre-cut and installed.
