I recommend oxyacetylene for brazing on refrigeration equipment. B torch takes longer to heat and you run the risk of overheating other components. Oxyacetylene heats quickly, allowing you to flow the alloy and pull the flame off sooner.
You can use oxyacetylene in NYC. Hospitals won't let you bring torches in without extensive approval. B torch (straight acetylene) is great for plumbing and anything soft soldered. Didn't say ditch it, just don't recommend for silver soldering, the melting point is near that of the copper. B torch takes a while to get there and the whole time you're heating, the heat is traveling to other components that can be damaged by excessive heat (e.g. valves, sight glasses, driers) even if you've taken pains to prevent it with wet rags and heat blocking putty.
1/2 to 3/8 may not be a big gap but its best to go with what the manufacturer asks for. It would suck to install it and have it not work due to a restriction.
I recommend removing used filter driers with cutters instead of brazing since the heat will expand the moisture and other build up into the system quicker than you can take it off

there's a time and a place for both setups, keep both around
Also there are rules for NYC travel and what buildings allow.

1:41 Oh dear what ref engineer left that there for the next person😢
Great job as always brother.
Another one in the can. As us older time video guys say
Why not use adapter unions?
Did you replace the time clock.
Great video. Thank you for sharing
High back pressure. It may need a TXV adjustment to see if its bad.
Very good 👍 love every thing ❤you make me so happy you are very smart and very good
Water valve is on the wrong side. Should be on the leaving side, not entering water

Is 1/2 to 3/8 considered a restriction?
@wrestlingterrier8366 Depending on the equipment it can be.
@@peteaceves5237 I see. Thanks !
