Copper pipe stretchers

Do the Pipe stretches work

Do these things work?

 

[Harvest Fields]

I believe so. Never used one. Aren’t they only for refrigeration and air con pipework?

 

[Bigboat1971]

Not sure as never used one but like the idea of it

Looks like a toy to me.
Doubt it will last long.

As above that's for refrigeration where the tube wall is thicker and the pipe is softer.

There was a tool in the late 60's for plumbing that expanded the pipe and came with a bag of solder rings that dropped into the expanded part, creating a capilliary fitting.

Thank guys for the info

Personally I have never trusted them

You can get pipe expanders for plumbing applications and at one time was common practice, they do work but with today's thin walled copper they are considered a risk. Personally I'd just stick to using end feed sockets.

I still have a 15mm and 22mm Monument Swaging Tools and use them on contemporary pipe. They bell out the pipe and do away with a straight coupling. I think they look neat. And you can make a slip coupling if required. Centralheatking

Those were standard issue with the old gas board ( for use on gas) back in the day. Think mine is still kicking around somewhere

I just looked at the Monument website. There is nothing there about it just being for air and fridge. Using mobile phone do can’t provide link, and as phones are useless, it is possible there is something I cannot see

Still got and occasionally use mine when going on to old pipework.

Rothenberger used to to a nice socket forming tool set.

Does work but not great. Would go for the rothenberger pipe expander with swappable heads

Pricey though, around £360 without VAT a couple of years ago when I bought a set for the workshop.

I’ve got the monument sagging tool you use with a hammer but find it quite slow/hard work. It’s easier if you de burr the pipe to start. I’ve got a set similar to attached imagine at work. I think they may be Sykes Pickvant I think. A lot quicker/easier and no risk of belting your hand with a hammer.
