Abstract: A high-pressure connection for corrosive fluids includes a female member having a female surface and a male member having a male surface, both of which may be formed from stainless steel. The male surface is configured to have a complementary shape to the female surface. A malleable coating substantially covers the male surface and may be formed from copper. The male surface is configured to be pressed into the female surface, to sandwich the malleable coating and effect a fluid seal therebetween. The female surface may be substantially frusto-conical and the male surface substantially spherical. A supply line may be brazed onto the male member and the malleable coating configured to act as a brazing compound therefore. The fluid seal may be characterized by the absence of a gasket or an o-ring and the malleable coating between 15 to 30 microns.
