Hose Torsion Tester

Hose Torsion Tester
A specialized testing instrument designed to evaluate the torsional durability and performance of flexible hoses—including rubber, plastic, and composite hoses—under repeated twisting forces. This machine simulates real-world scenarios where hoses are subjected to rotational stress, such as during installation, machinery operation, or vehicle movement, to assess resistance to cracking, leakage, or fitting detachment.

 

Equipped with precision torque controls, adjustable rotation angles (typically ±180° to ±720°), and optional internal pressure systems, the tester operates by:

 

  • Securing one end of the hose while rotating the other end through controlled angles at a set speed (e.g., 30 rotations per minute).
  • Applying continuous or cyclic torsion to replicate long-term torsional stress, with optional internal pressure (for hydraulic or fuel hoses) to simulate operational conditions.
  • Measuring key metrics: the number of cycles until failure (cracks, leaks, or loss of structural integrity) and the maximum torque the hose can withstand before damage.

 

Key applications include testing hoses for:

 

  • Automotive & Aerospace: Fuel lines, brake hoses, and coolant hoses exposed to twisting during vehicle movement or component adjustment.
  • Industrial & Hydraulics: Hydraulic hoses, pneumatic tubing, and industrial hoses used in construction, mining, or manufacturing machinery with rotating parts.
  • Marine & Agriculture: Irrigation hoses, chemical transfer hoses, and marine fuel lines subjected to torsional stress during handling or equipment operation.

 

Compliant with international standards such as SAE J2006, ISO 6945, and DIN 20066, this tester is trusted by hose manufacturers, quality control labs, and automotive suppliers. It ensures hoses maintain functionality under torsional stress, reducing the risk of premature failure, safety hazards, or operational downtime.
