This sleeving has excellent tear resistance and better abrasion resistance than standard polyester sleeving. Made of Nomex fabric, it resists most acids and alkalies, alcohol, hydraulic fluid, oil, gasoline, salt water, and solvents. It won’t irritate skin like fiberglass, so it’s easier to handle. Because this sleeving is non-expandable, it does not stretch, so it’s best for applications where you know the exact diameter of the items you need to protect.
