15% or 45%

[crazy eye]

for copper to steel ( compressor connection )what do you use ,15% or 45% ?

[jpsmith1cm]

Flux coated 45% It's orange rod.

[itsiceman]

Both

On bigger O.D.'s I lean towards 15%

and use 45% on the smaller stuff.

Use whatever your better at ;)

the biggest consern on a compresor connection is vibration the higher the silver content the more flexible the joint will be. I would sugest harris 45 it is a blue flux coted brazing rod.

15%. Cheaper, gets the job done somehow or another. Any comments?

[bdivell]

like hvacrjones said use the flux coated or use 15% with flux

[Dchappa21]

I use the 45% in the roll with harris white flux in a bottle.

[fireye03]

i was tought 45% with white flux so that's what i use

[refer guy]

what is the difference from the blue coated and the orange coated?thx

[hvacrjones]

most likly the brand harris 45 is a blue flux rod easy flow 45 is a non fluxed roll that you use stay-silv white past flux with. I do not know who makes the orange flux (maby sunkist :p)

[wildtech]

I belive blue is 45% and orange is 56%

[targetman]

45

[beachtech]

and there is the pink one too :)

works best for copper to brass :)

[mike robinson]

I use 15% with white flux but the soilder joint has to be clean.

[superheatrman]

45% harris with stay silv white paste, very clean tight joints, have fixed leaks between compressor body/pipe stub, can braze any steel to steel with that to..
