Bending soft copper tube by hand without support almost always ends the same way — a kink or a flat spot right at the bend, and a length of pipe that's no longer usable. The 8mm External Pipe Bending Spring fits around the outside of the tube, supporting it through the bend so the pressure of hand-bending is distributed evenly rather than concentrating at one point.
Made from cadmium-plated spring steel, it's built for repeated professional use rather than the occasional DIY bend. The coiled cone design and angled ends make it easy to slide on and off, even with longer tube runs, and the spring's shape is what actually prevents the compression and buckling that causes kinking in the first place — it's not just a sleeve, it's doing mechanical work through the bend.
Key Features & Benefits

Cadmium-Plated Spring Steel: Durable construction built for professional, repeated use.
Optimised Spring Form: Prevents compression and buckling in the bend radius.
Coiled Cone Design: Angled ends make handling easy, even with longer tube lengths.
No Powered Tooling Required: Achieves clean, professional bends by hand.
Ideal For

Plumbing, heating, and pipework installation.
On-site pipework adjustments without dedicated bending machines.
Plumbers, heating engineers, and DIY users.
Why Buy This Product?
A ruined length of copper tube from a botched freehand bend costs more in wasted material and time than this spring does outright. It's a cheap, durable way to get a clean bend without needing a dedicated bending tool on site, and the cadmium-plated steel means it'll outlast a fair number of jobs rather than wearing out after a handful of uses.
