Brazing or soldering copper cap tubing, filter dryer and access valves for refrigerators 

One thing I would recommend on saddle taps is, once you THINK you have successfully brazed on the saddle, you pressure test it PRIOR to piercing the line. If you find you h@ve a leak and the line was pierced, you’re screwed. I do mine with soft solder after having one unable to pierce the braze that was a bit too hard for the stem. If you make your own bubbles, use dawn and glycerin from the drug store. Glycerin is what makes the bubbles grow without breaking for the children toy bubbles. For very stay leaks I use simple green like around heads or service valves. The only caution is simple green will make your H10 react as if a leak, as will 409...

Great Video! Not overcomplicated and not rushed or edited to make you look good. Just great step by step teaching. Excellent video

Great video! Good job of explaining what and why you are doing things.

Very good detail. Thanks!

Can I use a portable propane torch

Great video Raleigh, lots of good tips. I see in a past comments you mentioned a nitrogen purge is optional in small systems. I try to always use nitrogen because without nitrogen I'm so worried about residue flaking off the copper tubing walls and clogging my cap tube. Has this ever happened to you??

Do you have any videos showing how a small diameter line is brazed perpendicular, without fittings, into a larger line? (for adding sensors etc)....

Raleigh... Never worked on a Refrigerator before but decided to tackle changing the Compressor on my Kenmore Elite...Stopped Cooling. Welded in the New Compressor and Filter/Dryer...pretty proud of myself at this point! Vacuumed out the system and let it set for 24 hours... held a Vacuum... even prouder still!! Put some R134A Refrigerant in but the system refused to get even a little bit cold!!!! System would only come out of Negative to 10!?!? What did I do wrong?

Awesome video. I don't have ascetalin tortch, so hoping propane torch works... I hope you finished conecting that drier filter up? I have a Fridgidaire electrolux and need to do what you've just done. Then, hook it up, flush the system and refill. I'm guessing? Really need some help! Can't afford repairman, and don't have a vacuumed pump. Not sure what to do? Your video was informative and well done. Appreciate ya!! 🙂

very good job. Thanks

Raleigh... The MAAP Gas wouldn't Faze the Welds on my Kenmore Elite/LG Refrigerator. Could it be the Factory used Brazing Rod and not Silver Solder?

Raleigh... How Critical is it to Flow Nitrogen while Silver Soldering on a Residential Refrigerator?

Maybe you should have turned the camera a little bit to the left so we could have a better look at the OSB block !

Raleigh...well, I think I have all the Tools to Replace the Compressor on my Kenmore Elite Refrigerator: Compressor, Filter, extra Copper Tube, Flux, 15% Rod, Bernzomatic Torch, MAAP Gas Bottle, Scale, Vacuum Pump, A/C Gauges, Filler Port, R135A Refrigerant, Adaptor, Valve and Tubing Cutter.

Proper flow & proper heat. Stay safe. 🥃🥃🍺🍺🍺🏌🍇 Retired keyboard super tech. Wear your safety glasses.

Very helpful. Thanks

how far do i put captube into drier

Why in hells manger do no appliance techs flow nitrogen to braze and pressure test? You have to know you are creating flakey copper corrosion products inside where you braze that can plug up cap tubes and introduce abrasive contaminants to oil. Also wet rags work just fine to isolate heat you dont need any fancy stuff. You also should be cleaning your copper with sand paper prior to cutting tubing or parts new or not.

I'm doing a Kenmore Elite (LG) French Door Refrigerator with Two Freezer Drawers.

I have a small crack in the liquid line at the bend just above the compressor. tight spot, wondering if I should use 15% or higher and also a jewelers torch so I can avoid over heating / damaging the compressor? Did this happen because the 3 compressor anchor bolts were tightened down too much causing too much vibration on the liquid line.

I bought a new Compressor for my Kenmore Elite Refrigerator and I am going to Change it myself. Question...will a Bernzomatic Torch with MAAP Gas Canister do the job? Or is Oxy Acetylene necessary?

When is it required to purge the copper lines with nitrogen while brazing?

Thank you for sharing

thanks for the tips

Raleigh...would you use 5% Rod on a Compressor Replacement?

If you have steel you have to use silver solider!

Have you every brazed using only propane with 15% silver brazing rod?

Thanks for sharing idea idol

Would propane torch work?

Do you Flush them out?

Raleigh...Well...it looks like my not giving up on the First-Time-Ever Refrigerator Repair is paying off Dividends in the form of a Repaired Unit! Freezer Temp started at +69 degrees...it is now +23 degrees. There were 3 issues that I encountered after getting the Compressor and Filter/Dryer Welded In: 1.) The Compressor would not Run. Turns out, the Male Pins on the Compressor itself are 180 degrees from the Old to the New. Fix...Rotate the Female Plug so that the two Power Pins engage leaving one unused Male Pin floating in mid air. Hoakey...yeah but it works. I'll call Sears Parts Direct & see if they have a proper Harness. 2.) One of my Welds at the Compressor/Condenser Joint let go after 24 hours. Fix...Reweld Joint and this time use a Mirror to Inspect the backside of the Weld. 3.) System would not come up out of Vacuum all the way with R134A Refrigerant installed thus unit would not get Cold. Fix...Cut Capillary Tube at Filter/Dryer and Inspect. Found Silver Solder Wicked up to end of Capillary Tube and Welded off Opening. Unweld joint and Reweld with Capillary Tube further into Filter/Dryer...not too far though. Pulled a Vacuum yesterday and let it set overnight...no Leaks. Charge the System with Refrigerant.

gday, instead of squeezing the tubing around the smaller one risking collapsing it, why not use appropriate size copper wire or small screw driver etc to set the size of the bigger tube, then slide the smaller one in.

How much acetylene,psi?? And oxygen???a little bit doesn't really do it!!!!but thanks for info!!!

Raleigh...my First Clue would have been the Thick White Pumice Buildup Material around the Welds.

Any nitrogen?

wud b helpful if u mention where to get the access valve or is smting that only hvac techs have access to.

Oh, don’t use these line taps on a flammable like R290... it’s becoming a lot more common.

What’s the part # on that cap tube

did you even look at this video before it was posted?????

I’m loving this dude. Lol just like that just like that mkay

hello friend...can I get away with with soddering household hvac with a regular propane torch, just propane no oxygen tank setup?..im still learning n the videos ive seen use a dual tank torch lik yours....allready have som regular propane torches, n im allready buying a gasoline oxygen torch

👍👍👍👍👍👍

Blow?

Why you not using flux when brazing?

Yeah...try $12 for Bubble Up

why is nothing in frame

Funny

You might want to pay attention to where your camera is pointing. I only see about 20% of what you're actually talking about in the beginning.

Good information, but a terrible work environment...I'd recommend having a nice clean background on the next video....still a thumbs up...thanks
