MAP MAP/Pro Torch Gas Cylinder 400g for Brazing and Soldering Copper Pipe in Refrigeration and Air Conditioning Work

Stock code MAP is a 400g cylinder of MAP/Pro torch gas. Refrigeration and air conditioning techs use this style of gas for brazing and soldering copper pipe, joining capillary tubes and repairing lines in the field. It screws onto a compatible hand torch, and it's generally chosen over plain propane for its hotter flame, which brings joints up to temperature faster.

Brazing and soldering with MAP/Pro gas

Getting copper joints hot enough, quickly and evenly, is the key to a good brazed joint. A hotter fuel gas helps heat thicker fittings and larger pipe sizes without long waits, which also limits heat creep into nearby components such as valves and filter driers. Typical jobs include replacing a compressor, fitting a filter drier, repairing a leak in a copper line or joining pipe on a split system install. Purge refrigeration lines with dry nitrogen while brazing, and protect anything heat sensitive with a wet rag or heat paste.

Safe use and storage

Check the torch is compatible with the cylinder before connecting, and screw it on hand tight without cross threading. Light it only in a well ventilated area clear of flammable materials, and keep a fire extinguisher close by. Close the torch valve and remove it from the cylinder when finished. Store cylinders upright, out of the sun and away from heat sources.

Questions about this part

Will this cylinder fit my torch?

It suits hand torches made for this style of screw-on gas cylinder. Check that the torch maker's instructions confirm it is rated for MAP/Pro or MAPP type gas, as some basic propane torch heads are not suited to the hotter fuel.
