Copper Pipe: Compression Fittings
For some installations, the piping are connected using compression fittings. These fittings
enable easy installation and dismantling. However, the cost for these fittings are higher.
They are also not as strong as brazing joints. Chances of leakage are higher.
Generally, the fittings have mounting rings which are slipped onto the copper pipes. The
ring is then pushed against the fitting internal surface and a locking nut is used to hold the
assembly together.
