How to get twists out of a coiled cable
Cables frequently develop deep torsion and twists from being coiled even when they have no cuts, cracks, or bulges. This severe twisting prevents the wire from straightening out and looking like a new cable.
What people tried
Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
- 1Walking the length of the cable out with another person to encourage twists to move and coil like a snake
- 2Placing the cable out on a hot sunny day to warm it up before pulling or straightening it
- 3Trying the triangle seatbelt buckle method from online videos
- 4Taking the vehicle to a dealer for professional repair
- 5Setting the roll in the sun to warm it up before installation
- 6Using tube talons, PEX clips, or heavy objects to hold it straight
- 7Buying 20-foot straight PEX joints and using couplings instead of coils
- 8Using a dedicated PEX straightener tool
- 9Bending it the opposite way of its memory
