@Dempsey: Brian how are the alu tubes connected in the rest of the fridge?

Welded?

Compression?

Adehsive jointing?

I am a bit surpised someone went to the TROUBLE of using alu as opposed to the prevailing choice: Copper!

When you see how rest of plumbing is joined up it may give you a clue as to best repair.

You may be able to cut out a larger length of pipe to go back to round tubing.

Thats wat Ive been hinting at for the last 2 weeks...

replace a section with 6mm copper and an insert (available from any hydraulic/ engineering supplier e.g ted johnson, Bradshaws) if the pipe is softish.

other option Round off the damaged section and use tec 7 and a small high quality jubilee ( like the old days) I have one ona 4 bar pipe for the last ten years!  Use tec 7 and a clip then gas with compressed air to check for leaks, it can be / would be flushed with Nitrogen I think before regassin.

Its not rocket science its a hole in a pipe

dempsey, did u check the filling port yet, if so send me a pic with dimensions.

They don't use copper when building fridges AFAIK. I pulled apart an undercounter fridge to redesign it as a better spaced fridge for corneys and it has the same slightly flat aluminium pipe. Googled it and have being to all the sites on offer now thinking of going down the road of JB Waterweld, alot of guys have used it on JBK.

Here is some pictures of the guts,

Pic. 3 shows a fair amount of copper doesn't it?

Looks like they then soldered aluminium into the copper sleeve. Should be able to replace the ally with copper.

BUT: Is it worth it? Just do what Tube suggests!

[DEMPSEY]

No you don't understand,I have built a lovely cabinet to wrap this freezer in. It hold 4 corneys and a pub gas bottle and is all on wheels. I will not accept that this cannot be repaired .

[DEMPSEY]

Can this be re-gassed WHEN I fix this hole.

[Will_D]

As this a mix of Aluminium and copper tubing/components, why not just replace the aly with copper. It looks like the aly is being used as the expansion side of the heat exchanger and could all be replaced with soldered copper bent where you need it and then its just a case of pressure test and re-gas.

What is the compression side heat exchanger made of (the bit thats in the fresh air to cool the compressed gas)?
