Rothenberger Pipe Bending Spring for Copper, External, 16mm/5/8" - 25186

Features of the Rothenberger 25186 Tube Bending Spring

The Rothenberger 25186 copper tube bending spring is a professional tool specifically designed for bending copper pipes with a diameter of 16mm or 5/8 inch. Made from high-quality materials, this external spring ensures precise and uniform bends without deforming or flattening the tube. The spiral design allows for even pressure distribution during bending, preserving the circular cross-section of the tube and maintaining an unaltered internal flow.

Practical Applications

This tool is used in numerous professional and DIY contexts:

• Installation and maintenance of domestic plumbing systems
• Construction of heating systems
• Installation of air conditioners and refrigeration systems
• Creation of gas circuits
• Automotive repairs
• Craft and DIY projects with copper tubing

Technical Advantages

The Rothenberger tube bending spring offers several benefits compared to other bending methods:

• Prevents crushing and deformation of the tube during bending
• Allows for bends with a constant and uniform radius
• Eliminates the risk of micro-fractures in the material
• Maintains the internal cross-section of the tube, ensuring optimal fluid flow
• Does not require heat sources to soften the copper
• Allows working in confined spaces where mechanical tube benders would be difficult to use

Technical Specifications

The Rothenberger 25186 tube bending spring has the following technical characteristics:

• Compatible diameter: 16mm (equivalent to 5/8 inch)
• Type: External spring (applied to the outer surface of the tube)
• Material: Hardened spring steel for maximum strength and durability
• Length: Optimized to allow bends up to 180°
• Finish: Anti-rust surface treatment
• Product code: 25186

How to Use

Using the Rothenberger tube bending spring is simple and intuitive. Simply insert the copper tube into the spring, ensuring that the area to be bent is completely covered by the spring itself. Then proceed to manually bend, applying gradual and constant pressure. The spring will accompany the movement, evenly distributing the force over the entire circumference of the tube, preventing deformation. For very tight radius bends, it is advisable to proceed gradually, performing the bend in several stages.

Maintenance and Storage

To ensure the longevity of the Rothenberger 25186 tube bending spring, it is recommended to clean it after each use, removing any dust or material residues. Store the tool in a dry environment to prevent rust formation. Avoid excessively forcing the spring beyond its natural bending radius to avoid compromising its elasticity and effectiveness over time.
