T-Bolt Hose Clamps

T-bolt Clamps

Winlong’s T-Bolt Hose Clamps are the ultimate solution for high-pressure and high-vibration applications. Unlike standard worm gear clamps, the T-bolt design provides superior tensile strength and a 360-degree uniform seal. These heavy-duty clamps are engineered for critical connections in turbochargers, intercoolers, and high-pressure industrial fluid systems, ensuring a leak-proof fit even under extreme mechanical loads.

  • High-Torque Fastening: The robust T-bolt and nylon-insert lock nut design allows for significantly higher torque levels than standard clamps.

  • 360° Uniform Sealing: Provides even radial pressure distribution, protecting hoses from damage while ensuring a tight, consistent grip.

  • Floating Bridge Design: Features a wide, high-strength bridge that prevents hose extrusion and maintains a secure seal under high pressure.

  • Corrosion Resistance: Available in multiple stainless steel grades (W2/W4/W5) to handle everything from standard industrial use to salt-water environments.

  • Heavy-Duty Automotive: Essential for turbocharger piping, intercooler systems, and high-pressure coolant lines in diesel engines.

  • Industrial Machinery: Used in hydraulic systems, pumping stations, and high-pressure air filtration units.

  • Agriculture & Construction: Ideal for heavy-duty tractors, earthmoving equipment, and irrigation mainlines.

  • Marine & Offshore: 316 Stainless Steel versions are the industry standard for marine exhaust systems and below-waterline piping (Marine Grade).
