ABSTRACT:
The invention relates to a hose fitting, more specifically, for a brake arrangement in a motor vehicle, for connecting, in a compression-proof manner, a multi-layer hose to a metallic end piece. At least part of one free end of the end piece engages with the inside of the hose and features at least one bulge, with a metallic pressed sleeve encompassing the hose, overlapping the bulge and also featuring, lateral to the bulge, respective first pressed sections. The crux of the invention is based on the fact that elastic and electrically nonconducting surface layers are arranged on the hose and end piece, upon which are arranged, in each case, a second pressed section in a liquid-tight manner. The invention is associated with the advantage that a hose fitting is sealed with respect to electrolyte penetration from the outside, and that, moreover, local cell formation, with resultant corrosion of the hose fitting, is prevented.
