GD pressfitting is very easy and quick to install and
only uses AISI 316L stainless steel, and carbon steel. The fittings used in pressfitting system have toroidal chamber at their own ends inside which there's a Oring, which has a very strong resistance against aging, it can resist to high pressures and also to temperatures. GD pressfitting, with electromechanical jaws are used for pressing the fittings on the tubes. The O-ring, once compressed, guarantees the connection to be completely sealed and no longer divisible.
