Spring Tube Benders Tubing Benders Spring for Pipe O.D.1/4, 5/16, 3/8, 1/2, 5/8 Inch Tube Bender Kit for Copper Aluminum Thin Wall Steel Tubing， 5 Pieces

Just based on a suggestion from a friend and the likelihood of receiving what was described in the listing, I feel positive and confident about using these.

Product worked good. And was as decribed by seller. Packaging was good

I wish the springs were longer, however I had no problem putting a 6 inch radius bend on a 5/8th inch pipe. It may seem weird, but the larger pipe is more inclined to kink than smaller diameter pipes, so getting a good bend on the pipe was very satisfying. So yes, they work, and against the cost of replacing a ruined pipe they are exceptional value.Particularly if you are planning to install your own mini-split system(s) this is an essential tool.

Spring thickness is a little thin. The larger sizes work ok but if your not careful you can ruin the spring when removing after bending the pipe.

Stick in the hose you want to make the bend, heat it up, and cool it down under cold water, hold it there for a few minutes and the hose is molded to the bend that you made. Works great, use it daily at the shop for bulk hoses bending.

These two Benders are complete garbage don't waste your money and purchase a real two-bender from a hardware store.

Used the 5/8 bender was able to make a 90 bend without crimping the tubing

Can’t beat it for the price
