External pipe bending spring LOGO-Tools 2.116 for 16 mm pipes

External pipe bending spring LOGO-Tools 2.116 for 16 mm pipes is a handheld support accessory designed to fit over 16 mm diameter tubing and maintain tube shape during manual bending. Made to be used with soft metal pipes such as copper, this bending spring reduces the risk of kinking and ovalisation when forming accurate bends for plumbing, heating or refrigeration installations. The spring’s external design provides consistent internal support along the bend radius while remaining simple to install and remove.

Advantages

The external bending spring provides uniform reinforcement along the bend location to minimise deformation and maintain flow capacity of the tube. Its form-fitting design for 16 mm pipes ensures a secure fit during bending operations and quick removal afterward. The tool is lightweight, requires no special equipment to use and helps achieve repeatable bends with reduced material waste and fewer reworks.

Suitable for (tasks / use cases)

• Bending 16 mm copper tubing for plumbing connections and water supply lines
• Forming bends in soft metal tubes in heating and radiator installations
• On-site refrigeration and air-conditioning tubing work where manual bends are needed
• Repair and modification tasks that require preserving tube inner diameter and flow

Key specifications

• Compatible pipe outer diameter: 16 mm
• Type: external bending spring for manual tube bending
• Suitable materials: copper and other soft metal tubing
• Function: prevents kinking and reduces ovalisation during bending
• Usage: reusable, removable after bending

How to use

Slide the external spring over the end of the tube until the section to be bent is covered by the spring coils. Hold the tube firmly and apply steady bending force at the chosen bend point, keeping the spring in place to support the tube wall. Once the desired bend angle is achieved, straighten the tube ends as needed and slide the spring off. Inspect the bend to confirm there is no kink or significant ovality before installation.

Usage recommendations

Use with clean, deburred tubing and avoid excessive repetitive bending at the same point. For hard or heavily work-hardened materials, consider using a dedicated bending tool. Store the spring in a dry place to avoid corrosion and check for deformation before use to ensure consistent support during bending.
