black oxide coated one-piece fittings
Black oxide coated one-piece hose fittings undergo a conversion coating process that forms a thin, adherent layer of iron oxide on the steel surface. This layer enhances the fitting’s corrosion resistance and provides a uniform, matte black finish that is both protective and visually discreet. The black oxide coating is wear-resistant and does not significantly alter the fitting’s dimensions, making it suitable for precision applications. These fittings are widely used in automotive, machinery, and industrial equipment manufacturing where a balance of aesthetics and functionality is required.
