I'm trying to connect 2 small pieces of brass pipe together (13/32 OD) using MAP gas and I thought I could just use the bronze rods they sell at home Depot but all that did was sit on there and never melt even though the brass and it were red hot.

Had the white flux coated rod and the flux was melted just fine.

Looking online now, some pages say I need to use copper rods, or copper-phosphorous rods and others say I gotta use silver infused stainless steel rods.

Can someone explain what type of brazing rod I need to use because its not making sense to me.

You need something that melts at a lower temperature than brass. Silver solder (a type of brazing rod with 5% silver) worked for me last time.

This is brazing, so yeah it will be red hot before it melts.

There are three ways to do it depending on the looks and strength of the joint. First is using silver solder with MAPP or Oxy-propane and flux. Second is using 10% phosphor copper brazing rod using Oxy acetylene or Propane-Oxygen. Last is strongest and best looking, Tig welding using special brass filler rod.
