High Temperature Electrical Wire Sleeve Acrylic Resin Coated Fiberglass Sleeving

Volsun High Temperature Electrical Wire Sleeve is a reliable, easy-to-use solution for protecting wires and cables in demanding environments. Made from woven fiberglass and coated with a clear acrylic resin, this sleeving combines strong thermal resistance with flexible handling. It resists heat, abrasion, and many chemicals, making it suitable for automotive, industrial, and household electrical applications

The fiberglass core gives the sleeve excellent thermal stability. It can withstand high temperatures without melting, shrinking, or losing its shape, providing long-term protection for insulation and conductors. The acrylic resin coating adds extra strength and helps the sleeve maintain its woven structure while improving abrasion resistance and reducing fraying at cut ends. Together, these materials create a durable cover that performs well where heat and rough conditions are expected

Volsun sleeving is simple to install. It slips easily over bundles of wires, harnesses, hoses, and tubes, and conforms to irregular shapes without bunching or kinking. The flexible nature of the material allows for neat routing through tight spaces and around bends. For added security, the ends can be fixed with heat-shrink tubing, clamps, or adhesive. The sleeving is available in multiple diameters to fit single wires or larger cable groups, giving you options for different project sizes

Safety is a key advantage of Volsun High Temperature Electrical Wire Sleeve. It helps prevent electrical shorts by insulating wires and reducing the risk of contact with sharp edges or hot surfaces. The sleeve’s resistance to flames and high temperatures adds an extra layer of protection in case of overload or component failure. This makes it a good choice for engine compartments, industrial machinery, and other high-heat locations

Maintenance is minimal. The smooth acrylic surface is easy to clean and does not trap dirt or moisture, so the sleeve remains effective over time. Its resistance to many common chemicals and oils means it will continue to protect wiring in environments where exposure is likely

Volsun High Temperature Electrical Wire Sleeve is a practical, cost-effective way to protect critical wiring systems. With strong thermal performance, durable construction, and straightforward installation, it’s designed to keep electrical assemblies safer and more reliable in tough conditions
