Condenser inlet is too big?

[kay86]

Hello! I've noticed my 350W condenser have huge inlet, like 8mm OD. I cannot fit 8mm and I don't dare swaging it because the thickness appears to be already too thin, even if the thing is rated for 300+ PSI. I think I'm supposed to fit the 5mm OD tube because it's the correct size for the compressor's discharge but how am I going to fit a 5mm OD in that huge inlet? I would have to put a lot of brazing, but wouldn't it make for a weak joint? I thought I studied that the gap must not be too wide, just enough to have a capillary effect that coats the inside of the joint. So what gives?

A reducer, if you can get one that goes from 8 to 5 mm. Have one made?

Make your own reducer with a series short length of pipe increasing/decreasing in diameter, expanding the pipe if needed or to try and reduce the number of steps.

Or a rough method, crimp the edge of the 8mm pipe at one point around the 5mm pipe. Probably want to heat the 8mm pipe up first though.

I guess it depends on if it needs to look good or if its just an experiment.

Sorry I was being an idiot. Actually if I push a little the 8mm does fit pretty snuggly. No swedging required

You are right that the gap should not be too wide. However, you can bridge the gap between the 8mm OD tube and the 5mm OD tube with a reducer fitting. This would allow you to make a secure connection without risking weakening the joint. Additionally, you may need to apply flux to ensure that the brazing process properly seals the joint.

Hi Houston, thanks for your reply. I believe some brazing rods have the flux around them, expecially the high silver content ones used in refrigeration, am I correct?

Your acid flux will enter inside the tubes contaminating the refrigerant... use silphos rods.
Cut a small end pipe as in your 1st picture, insert it in the condenser and the insert your 2nd smaller pipe in this small end.
