Colorno, May, 9^th 2025. Bolt tensioning equipment often operates in some of the harshest environments, from offshore platforms to heavy construction sites. These systems face extreme pressures, severe fatigue, and often marine environments that can compromise component life. They also often work in confined spaces, requiring hoses that offer high flexibility and easy handling.
 
To address these challenges, Transfer Oil has developed the 2441 thermoplastic hose, part of our HELIX range of Ultra High Pressure (UHP) hoses. Specifically engineered for bolt tensioning systems, the 2441 is built to meet the stringent demands of modern hydraulic tools, providing mechanical strength, pressure performance, and long life.
 
Watch the video below to hear from our CEO, Ugo Ferrari, and General Manager, Stefano Galbussera, as they explain the advanced engineering behind the 2441 hose.




Key Features and Benefits of the 2441 Hose:
 

• High Pressure Capability – Rated for 1,800 bar (26,100 psi) with a 2.5:1 safety factor (for the standard 3/16” size), the 2441 handles extreme pressures with ease, ensuring reliable performance under harsh conditions. 
• Multispiral Steel Reinforcement – Constructed with four layers of high-tensile steel wire, the 2441 combines mechanical strength and pressure resistance with the flexibility needed for quick installation in tight spaces. 
• Compact and Flexible Design – With a reduced bend radius, the 2441 is ideal for use in confined spaces, speeding up setup and reducing operator fatigue. 
• Protective Options for Harsh Environments – While the hose itself is built to resist demanding conditions, optional accessories like a crystal clear PVC protection jacket are available to extend hose life in the most extreme use. 

Every 2441 hose is engineered for long service life and high cycle performance, providing consistent reliability in harsh operational environments. With its lightweight and flexible construction, this hose is the ideal choice for bolt tensioning applications where precision, speed, and reliability are critical.
