High-Performance Flexible Spring Protective Sleeve/Conduit
Low-Friction Sheath for Control Cables | Fully Customizable Production Supported
This series of spring sleeves is not a simple coiled tube, but is precisely manufactured with a three-layer composite structure, where each layer synergistically delivers extreme performance:
- Outer Layer (Black Polymer Jacket): Made of high-strength, wear-resistant PVC\PP\PA6\PE\TPE\TPEE. Extruded and tightly coated over the armored layer, it provides excellent insulation, weather resistance, and UV resistance, preventing the metal layer from rusting.
- Middle Layer (Spring Armored Framework): Made of high-carbon steel strip or stainless steel strip. Formed by precision equipment through spiral continuous interlocking winding to create a high-strength metal skeleton. This gives the sleeve extremely high compressive, tensile, and torsional strength, ensuring it does not deform under complex working conditions.
- Inner Layer (Optional Extruded Plastic Liner): Can be made of PE\POM\PTFE\PA\PBT, etc. Closely fitted to the inner wall of the metal, it significantly reduces the friction coefficient between the control cable and the metal wire, protecting the inner core steel wire and greatly extending the service life.
Flexible Spring Protective Sleeve/Conduit Core Technical Advantages
Typical Application Fields of Flexible Spring Protective Sleeve/Conduit
Flexible spring cable conduit provides reliable protection for control cables and wiring systems exposed to repeated bending, vibration, compression and abrasion across automotive, marine and electronic applications.
Automotive Industry
Automotive Cable Protection
Spring cable conduit is used to protect brake, gearshift, clutch, seat adjustment and door lock cable systems from bending, abrasion, vibration and compression. Its flexible spiral structure allows smooth cable movement while the reinforced metal layer provides reliable mechanical protection in demanding automotive environments.
Marine Industry
Marine Control Cable Protection
Designed for marine control systems, spring cable conduit protects steering, throttle, reverse and gearshift cables from moisture, vibration, abrasion and mechanical impact. It can also be used for hatch, porthole and deck-cover control cables where flexible movement and durable protection are required.
Electronic Wiring Harnesses
Wiring Harness & Cable Protection
Flexible spring conduit provides anti-abrasion and anti-bending protection for wiring harnesses used in robotics, aviation and other equipment with frequent cable movement. The reinforced structure helps protect wires from mechanical damage while maintaining flexibility for routing and repeated movement.
Custom Spring Protective Conduit Manufacturing (Service Capabilities)
We manufacture custom spring cable conduit according to application requirements, drawings and assembly specifications. Customers can customize the metal reinforcement, polymer jacket, inner liner, diameter, spring pitch, length, color and end treatment.
Material Customization
The armored layer can be carbon steel (high cost-effectiveness) or stainless steel (high rust resistance); the outer jacket can be PVC, TPU, PE; the inner liner can be PTFE, PA, etc.
Color Customization
The color of the outer jacket can be customized arbitrarily (black, red, blue, grey, transparent, etc.).
Dimensions & Specifications
Inner diameter, outer diameter, and spring pitch can be precisely customized according to drawings.
Length & Packaging
Available in fixed-length cutting (accurate to the millimeter) or coiled rolls, with packaging customizable to export standards or client requirements.
End Processing
We offer various post-processing options such as end riveting, flaring, flattening, and threading to facilitate direct assembly.
