Anyone on here do brazing?

[scoobydo]

need to debraze a fitting braze a piece of 3/8 line back into fitting then couple onto condensor.

Tks

Most decent 'old school' garages or engineering workshops will do this sort of thing.

You could even try your local bus garage or train maintenance depot.

I know a guy who's braising is awesome but I'm in Mansfield.

Ive got a bit of experience under my belt





Made plenty of custom connections for aircon swaps, oil coolers etc

[scoobydo]

Dan that looks nice work. Made a right mess up pushing car back into the garage when it started raining. Had the front of the car off and as I pushed the car back in the flexible lines had draped down and got caught on the wheels ripping the fittings of the condensers.



This is the bit I need de brazing from the fitting with a new bit of pipe let in 3/8ths.



This will then need joining onto the damaged condenser


unfortunately It done two of the fittings

[DanThe]

The condenser tubing is copper, not something im familiar with in terms of brazing. Your car looks like a 333i? Im guessing the condensers are a bit special and not easily replaced, so its not really something I would like to test my skills on!

[scoobydo]

Yes it is a 333i, not factory AC though, it came with PAS as you couldnt have both from BMW. The AC install is aftermarket from diavia. Yes copper, beauty of copper is it is so easy to swage out for cost free couplers. Just a case of getting the right temperature but as you say need to test on a few bits of copper first. Spoke to a guy up the road who does commercial refrigeration he said he would give it a go, prefer someone on here though who likes cars.

here is a better picture of the damage, all doable I reckon

Just a thought - Plumbers regularly solder copper pipes together. Would this acheive the same outcome?

[scoobydo]

Soldering is not approved for AC lines unfortunately. You can get some compression type fittings, slightly different to normal plumbing ones but prefer brazed.

This is the guy for the job. It's what he does on a daily basis.

Most rad repair places will do it too. That's the kind of thing they would do regularly.

I thought aircon and fridge repairs were done with silver solder as it is stronger than lead solder and doesn't need the heat of brass .
