V-Band Clamps

Winlong’s V-Band Clamps offer a high-strength, leak-proof fastening solution for flanged joints. Designed with a specialized V-retainer profile, these clamps apply uniform radial pressure to pull flanges together, creating a gas-tight and liquid-tight seal. They are engineered for high-performance systems where frequent disassembly is required, providing a heavy-duty connection that is both space-saving and extremely reliable under high-vibration conditions.

  • Self-Aligning Connection: The V-shaped inner profile ensures the flanges are perfectly aligned and centered as the clamp is tightened.

  • Rapid Assembly & Disassembly: The single-bolt T-Bolt fastening system allows for quick maintenance, making it ideal for systems that require frequent cleaning or inspection.

  • Extreme Temperature & Pressure Resistance: Built to withstand the high thermal loads of exhaust and turbocharger systems without compromising seal integrity.

  • Compact Footprint: Offers a much smaller and lighter profile compared to traditional bolted flange connections, saving critical space in engine bays and industrial skids.

  • Automotive & Racing: High-performance exhaust systems, turbocharger outlets, and downpipes.

  • Industrial Equipment: Connection of pump housings, filtration units, and industrial centrifugal blowers.

  • Aerospace & Power Gen: Used in turbine housing connections and high-temperature ducting.

  • Marine & Offshore: 316 Stainless Steel versions for marine engine exhaust and cooling water intake systems (Marine Grade).
