Swaging Kit – A swaging tool kit may be needed to
expand system tubing to fit replacement parts. (Fig. 19)
Heat Gun – A heat gun can be used to heat a non-operating compressor or the
evaporator during purge and the refrigerant tank to increase charging pressure.
Many heat guns have a stand that allows continuous operation while other
repairs are made. A heat gun rated at 1500 watts or greater is recommended.

Single MC-Size Fuel Tank of Acetylene with a Double Tip Torch – The
MC-size single fuel tank of acetylene gas is very portable and easy to use. Two
torches are acceptable for use: A double-tip torch heats both sides of the joint
at the same time and is less likely to scorch the inside of the tubing; A single-
tip Turbo-brand torch equipped with a flame reflector will also heat both sides
of a joint and provide a hotter flame. A striker is used to light the torch.
15% Silver Brazing Alloy (Silfos) – Silfos can be used for all
copper to copper sealed system brazing. (Fig. 12) A 45 % silver
solder and flux must be used to braze copper to steel. (Fig. 13)
