External bending spring for PEX-AL-PEX pipe 20 mm GEKO G00897 (pack of 30)

External bending spring for PEX-AL-PEX pipe 20 mm by GEKO is a metal support device designed to be fitted over flexible multilayer pipe during manual bending. The spring preserves the pipe's round profile, reduces the risk of kinking and local flattening, and helps achieve uniform, controlled curves for plumbing and heating installations. Packaged as a set of 30 identical springs, this accessory is intended for tradespeople and installers who need a reliable method to shape 20 mm PEX-AL-PEX tubing on site.

Advantages

The bending spring maintains pipe roundness throughout the bending process, ensuring even wall thickness and minimizing flow restriction points. It is quick to apply and remove, allowing faster manual shaping without special tooling. Supplied in a multi-piece pack, it supports repetitive bending tasks and small repair jobs while reducing material waste due to improperly formed bends.

Suitable for

• Shaping 20 mm PEX-AL-PEX pipes during installation of heating circuits and potable water lines
• On-site repairs and retrofit work requiring controlled pipe bends
• Small plumbing jobs, prototypes, and temporary installations where manual bending is used

Key specifications

• Intended pipe outer diameter: 20 mm PEX-AL-PEX tubing
• Material: spring steel (external coil design for support during bending)
• Quantity per pack: 30 springs
• Function: prevents kinking and preserves circular profile during manual bending

How to use

Slide a single bending spring over the section of pipe to be bent so the coils encase the pipe circumference. Hold the spring firmly in position and bend the pipe manually to the required curvature; the spring distributes compressive forces and prevents local collapse. After achieving the desired bend angle, slide the spring off or leave it in place depending on installation practice and accessibility requirements. For repeated bends, use a new spring from the pack for consistent results.

Usage recommendations

Ensure the pipe is clean and free from debris before applying the spring. Avoid using the bending spring on pipes with fittings already attached in the bending zone. For tight radii or where manufacturer bending limits apply, check the pipe manufacturer's minimum bend radius to prevent overstressing the tubing.
