A method of manufacturing a male tube fitting (10) comprises the following steps: a) providing a male tube fitting (10); b) applying an anti-corrosion layer (20) onto the male tube fitting (10); c) applying a friction-reducing layer (30), which consists of a material having organic constituents and inorganic constituents, onto the anti-corrosion layer (20), thereby obtaining a coating which has a first friction coefficient (μ1); and d) modulating the friction-reducing layer (30) at least in selected sections (12) by breaking up molecules in the friction-reducing layer (30) to reduce the quantity of organic constituents in relation to the quantity of inorganic constituents in the friction-reducing layer (30), thereby obtaining a coating which has a second friction coefficient (μ2) higher than the first friction coefficient (μ1) in some selected places.
