High Torque Hose Clamps

High Torque Clamps

Winlong’s High Torque Worm Drive Hose Clamps are designed for heavy-duty applications where standard clamps simply aren't enough. Featuring a non-perforated band and a reinforced housing, these clamps provide exceptional radial distribution of pressure and extremely high sealing force. They are the ideal solution for high-pressure silicone hoses and industrial piping that require a reliable, leak-proof seal under extreme tension.
Band 5/8" band width / 9/16" band width / 1/2" band width 300 stainless steel
Screw 5/16" hex head screw 300 stainless steel
Housing 300 stainless steel

  • Solid Band Design: The non-perforated band protects soft hoses (like silicone) from being extruded or sheared, extending the life of the connection.

  • High Tightening Torque: Enhanced screw and housing design allows for significantly higher torque compared to standard worm gear clamps.

  • Safety Edges: Rolled-up band edges ensure that there are no sharp surfaces to cut the hose during installation or high-vibration use.

  • Extreme Durability: Precision-manufactured to withstand high mechanical loads and harsh environmental conditions.

  • Automotive & Racing: High-pressure turbocharger (intercooler) hoses and cooling systems.

  • Heavy Construction: Hydraulic lines and heavy-duty radiator hoses for earthmoving equipment.

  • Agriculture: Large-scale irrigation systems and high-pressure fluid delivery.

  • Marine & Offshore: 316 Stainless Steel versions for critical engine room piping and saltwater environments.
