Abstract
A fastening means, such as a hose end fitting comprising a metallic member formed with a serrated surface, and a layer of polymeric material arranged to cover the serrated surface, the surface of the layer of polymeric material both facing and remote from the serrated surface being capable of conforming substantially to the shape of the serrated surface.
Claims23
A hose assembly capable of operating in pulsating pressure conditions, comprising:
- a hose;
- hose fastening means attached to an end portion of the hose and including a metallic member having a serrated surface, said serrated surface having a plurality of inclined serrations which are shaped to resist removal of the hose from the metallic member;
- and a thin annular first layer of polymeric material disposed between the hose and the serrated surface of the metallic member and extending along the serrated surface and only along the attached end portion of the hose, the thin layer of polymeric material being subject to compression forces between the hose and the metallic member, and inner and outer surfaces of the layer conforming, adjacent both the hose and the metallic member, substantially to the shape of the serrated surface.
