Lined Clamps

Winlong’s Lined Hose Clamps are specifically designed for use with soft-surface hoses, such as silicone and rubber. The integrated liner extends under the gear mechanism and perforated band to prevent hose extrusion and shearing. This design ensures a consistent 360-degree seal while protecting the structural integrity of your high-value hoses in demanding environments.

  • Integral Liner Protection: The smooth inner liner covers the band perforations, protecting soft hoses from being cut or forced through the slots during tightening.

  • Even Pressure Distribution: Provides a uniform seal around the entire circumference of the hose, eliminating leak paths.

  • Corrosion Resistant Material: Available in high-grade stainless steel options for long-term durability in automotive and industrial settings.

  • Precision Tightening: Equipped with a rugged housing and a smooth-running screw for high-torque applications without slipping.

  • Automotive & Racing: Critical for silicone radiator hoses, turbocharger bypass valves, and vacuum lines.

  • Heavy Duty Trucks: High-temperature cooling systems and charge air cooler (CAC) connections.

  • Construction & Agriculture: Protection for soft rubber hoses in engine management and fluid transport.
