Overview
The Plumbworx External Bending Spring 3/4" O.D Tube is a precision tool for creating smooth, kink-free bends in soft copper, aluminium, or thin-walled tubing. Slid over the outside of the tube, it supports the wall during bending to prevent flattening, creasing, or collapse – essential for clean 90° or custom bends in plumbing, refrigeration, gas lines, or HVAC installations without needing a powered bender.
Why You’ll Love It
- Prevents kinks and wrinkles for professional, leak-free bends
- Easy to slide on and off with the flared end or pulling loop
- Compact and portable for on-site or workshop use
Built for Real Work
High-quality spring steel is tightly wound for firm external support while remaining flexible to follow the bend path. The 3/4" O.D size suits standard soft copper tube (common in larger plumbing and refrigeration lines), with a smooth interior to avoid scratching the tube surface. Tough and reusable for repeated bends on jobs like installing water supply lines, gas pipes, or air conditioning systems – a simple, effective solution for plumbers and installers who need reliable results without expensive mandrel equipment.
Perfect For
- Plumbers bending copper pipe for water, gas, or drainage installs
