Performance
High Flexibility: The corrugated design accommodates axial compression/extension and lateral bending, making it ideal for moving vehicle components.
Environmental Sealing: Provides a waterproof and dustproof seal, preventing contaminants from damaging internal wiring, linkages, or fluid lines.
Vibration & Shock Absorption: EPDM rubber effectively dampens mechanical vibration and shock, reducing stress on connected components.
Wide Temperature Resistance: Operates reliably in temperatures ranging from -40°C to 150°C, suitable for under-hood, chassis, and cabin environments.
Chemical Resistance: Resists degradation from automotive fluids, oils, and cleaning agents, ensuring long-term performance in harsh conditions.
Long Service Life: Withstands millions of flex cycles without cracking or losing sealing properties.
Application
Gear Shift Linkage Protection: Shields manual/automotive transmission linkages from dust and moisture.
Wiring Harness Routing: Protects flexible wiring sections in door, trunk, or hood assemblies, accommodating repeated opening/closing.
Fluid Line Protection: Covers brake, fuel, or coolant lines in the chassis, preventing abrasion and corrosion.
Suspension & Steering Components: Seals ball joints, tie rods, and suspension linkages from road debris and water.
Industrial Machinery: Also used in construction equipment and agricultural machinery to protect moving mechanical parts.
