Automotive hoses face a variety of challenges depending on their location, function, and vehicle type. Fuel lines, coolant hoses, air conditioning pipes, and high-voltage EV cooling lines all operate in harsh conditions. Choosing the right protective solution requires understanding the specific demands of each application.
Here's how our abrasion-resistant woven heat shrink tubing addresses different automotive hose needs:
1. Protection Against Mechanical Wear
Hoses often rub against engine parts, brackets, or tight chassis spaces, causing abrasion over time. Our woven heat shrink tubing provides high-strength wear resistance, meeting GMW14327 class >7 standards and surviving over 100,000 friction cycles. This significantly extends hose lifespan and reduces maintenance costs.
2. High and Low Temperature Reliability
Hoses in engine bays or near exhaust systems are exposed to extreme temperatures, while hoses in cold climates must resist brittleness. Our tubing performs in temperatures from -40℃ to +150℃, passing 1,000 hours at 150℃ high-temperature tests and remaining flexible after 4 hours at -40℃.
3. Chemical and Fluid Resistance
Fuel, coolant, and other automotive fluids can degrade hoses over time. Tested to GMW14327, our tubing provides chemical-resistant protection, ensuring hoses maintain integrity even in fluid-rich environments.
4. Precise Fit and Easy Installation
The 2:1 shrink ratio guarantees uniform, tight shrinkage over hoses. It can be installed using a heat gun or tunnel furnace, forming a secure, slip-free layer while maintaining flexibility for installation in tight or complex layouts.
5. Scalable Supply for OEM Production
Automotive manufacturers often need consistent, high-volume supply. Available in diameters 15 mm–50 mm, our tubing can be produced in large batches, supporting orders that cover up to six months of stock.
Applications Across Automotive Systems
Engine coolant hoses: Protect against friction with brackets and components.
Fuel lines: Prevent wear and chemical damage.
Air conditioning hoses: Reduce vibration wear and extend service life.
EV high-voltage and cooling hoses: Ensure safety, heat resistance, and durability.
Every hose has its unique challenges. Our abrasion-resistant woven heat shrink tubing is engineered to meet a wide range of protection needs, combining abrasion resistance, chemical resistance, temperature tolerance, and precise shrink fit. From passenger vehicles to electric cars, it ensures hoses remain reliable, safe, and durable in every environment.
