View the thread, titled "Bending 15mm copper 180 degrees?" which is posted in UK Plumbers Forums on UK Plumbers Forums.

I have a Draper 34212 lever bender. I know it isn't a Hilmor but I don't bend 3/4" much so it does the job. The one thing that is difficult is bending 180 degrees. Do you guys have any tips? Obviously I can do two 90 degree bends with a gap between but often I need a 180.

I was thinking of adding another catch to the frame so I could bend once then move the pipe forward some and finish the bend.

I am in the states so there isn't any help available to me as not many guys bend copper and when they do it is usually with a different style bender.
 
It's 5/8" on the Outer Dimension, we call it 1/2" as that is the inside dimension and pipes are called by their ID. Tubing is referred to by it's OD. Both copper pipe and tubing have the same dimensions but are named differently because of their physical properties. 1/2" water piping is 5/8" tubing size.

The physical differences being that tubing is used for HVAC and is softer so you can bend it by hand and it has been cleaned and filled with nitrogen. Tubing also comes in rolls precovered with either yellow or orange for gas or fuel oil. Water piping comes in straight lengths and doesn't have plugs in the end. Water piping comes in DWV, the thinnest, for drains, M which is used for heating, L which is the standard for potable water, and K which is the thickest and used underground. Tubing comes only in K thickness, the thickest.

The 1/2" pipe I bend is a bit of a tight fit in the lever bender, the 3/4" fits perfectly. I actually like the tight fit of the 1/2" as it makes it easier to hold everything together.

I was hoping you guys had a trick for bending 180's on a lever bender as it seems most of you use lever benders for water piping. I guess I will have to try to add another catch.
 
I also have the hilmor 1926598 Compact Bender Kit but it won't work because it is for soft copper. The 1/2" L pipe we get is "hard" copper. I put that in quotes because there are different grades of hardness/temper. For the most part we get mueller streamline which is bend temper. That means you can bend it with a lever or geared bender but it is still relatively hard and difficult to bend by hand. Soft copper can easily be bent but costs more because it takes more gas to heat up the copper and make it softer.

You really don't want soft copper for water piping as it will more easily erode, won't hold as much pressure, and doesn't look as neat. It will require more hangers to support it.

Maybe I will just make some 180's at the shop with the geared bender and keep them in the van. I usually only need them for toilet tempering valves and frost-free hose spigots under kitchen sinks.
 
It does look really nice, can't find any sites that ship to the states though 🙁
