5/8 line bending advice

Looking for any advice/input on bending 5/8 mini split line. Will I struggle to do so by hand? I did pick up a set of the plastic inserts ez bend colored things to be safe… I am mostly concerned about the initial 90 degree bend out of the wall. The lines run straight back through a 2x6 wall so my wall unit connections will be outside and after the bend. The first 10 inches of the stubs are spiraled but I believe the wall 90 will be on non spiraled section up towards the connectors. I believe the connectors on the stubs will be in the way of adding a spring or inserting the ez bend inserts. Should I get a tool for the 5/8 line? Thanks for any input

Bend in a none spiraled area of tube....

If you have a 5/8 EZbend insert a 90 degree is a piece of cake. Bend away without a thought. If you have multiple bends in a lineset, using a EZbend insert it becomes a bit scary; it become difficult to extract (pull) the insert. The most bends I have done on one tube is (5) , It took about 20 minutes of pulling to get the insert out; that was really scary. One bend will not be an issue
To add, with a 2x6 wall you can have a gentle bend. I just about finished installing (5) single zone minisplits in my home, hiding the linesets within 2x4 walls. Used the EZbend inserts on everyone of them, all had multiple bends, some bends shaped like small U bends within 16" on center wall spaces, no problems other then tough Ezbend pulls at times.

Took a quick look at you other post. I would place the outside unit at least 2-3 feet from the door opening. Also do not mount on the wall, sound and vibration will not be pleasant

I’ve used spring benders. I remove the insulation make a bend and pull the bender to the next fitting or back it off. It works depending upon your lay-out.

I've only installed three units so far (four more to do next year). None had spiral lines but being careful I haven't had any trouble making careful bends by hand without any issues. All of mine have at least two 90 degree bends in the run.

Everyone is bending 5/8 lines by hand? I had read that once you get to 5/8 it becomes more challenging.
BUT I had a eureka earlier… order a decent 5/8 lever bender from Amazon, make my 3 bends, and then drop that sucker at kohls

If possible get you pipe bender like electricians use to bend pipe. You won’t find 5/8 but 3/4 work. I use to care those bending springs and they actually work but hard time getting them off

"Ratchet benders are great for bending copper,but you need to bend it before putting copper through the wall."

One of the most important things about EZbend mandrels, pre-bending is not necessary nor is worrying about kinking as you push or pull linesets.

“Becomes more challenging.” It is difficult to bend soft copper by hand. The problem is that the copper work hardens and it does it right away. It is butter smooth while you roll it out. You are thinking, “aw, this is going to be great” Then you begin the bending and it kicks your ***. I think on the 5/8 you are definitely going to need mechanical help. Fitter says it all really. Lay-out, lay-out, lay-out. You can so easily work yourself into a corner.

Thanks for causing the prices of benders to go up a little as the market will spread the costs of your poor citizenship to those who buy and keep the tools they use.

D-bag move.

Kinda like warrantying tools picked up at swap meets or other such sales.

I'll pile on, what a jackass move. And you're proud of it!
