Spark-Resistant Tube Sleeving
A specially formulated silicone rubber coating on this fiberglass sleeving sheds sparks, molten metal splash, hydraulic fuel, and lubricating oil. Exposure to a torch will char the coating, but will not scorch the fiberglass inner layer. It also resists fraying. 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.
Snap-Close Wrap-Around Sleeving
Snaps keep this sleeving securely closed, yet permit quick access to contents and allow you to route wires in between the snaps. Wrap it around wire, cable, and hose without disconnecting them. Made of PVC-coated polyester, it has good chemical resistance.
