Limited success with air acetylene or propane
Worked on copper and galvanized steel air propane with good benzomatic torch, better flow with Hobart brazing flux granuals and with air acetylene torch. Fine for smaller copper on copper joining. Almost no flow on copper to stainless steel even with flux with these torches. Not as nice flow as brazing with some silver in the filler rod. Likely able to work with 1 in and larger with oxygen and flux.

Will work with Mapp gas
Update- if windy at all it is harder to use with map/pro gas. Takes awhile. I've had mix results have to get it pretty hot. Going still use thse buy may get acetylene air set up Have used 3 times in 3 weeks for some smaller brazes 2 on ac low side and 1 braze on high. Checked 2 today after about 2 weeks and both have held charge to the T. I use Mapp gas so have to just get that pipe hot it will liquefy with Mapp.

Excellent value for the purpose
Used this item to braze some HVAC copper tubing (thin wall) using MAPP gas. Meltability and flowability were as advertised. Product worked equally well in horizontal and vertical joint orientations. Very pleased with this product.

I got these for copper brazing and they work great, and with no need for adding flux.
