A pipe coupling includes a pipe branch, a hose, and a retainer. The pipe branch forms a proximal branch section, a distal branch section, and an expanded section with an increased diameter therebetween. The hose includes an opening that receives the proximal branch section and includes a proximal fold, a distal fold, and a gasket therebetween. The gasket is arranged to seal between the hose and the proximal branch section. The retainer is configured to enclose the pipe branch and the hose and forms a proximal flange and a distal flange. The proximal flange and the distal flange both extend inwardly and define a passage for the pipe branch, the passage having a diameter which is smaller than the increased diameter. The proximal flange engages the proximal fold and the distal flange engages the distal branch section. The pipe coupling provides an easy and reliable connection between vibrating machine components.

Hose coupling

A wind turbine nacelle comprising a plurality of power generating components and a fluid system, wherein the nacelle includes a nacelle cover comprising a lower cover or 'base', a roof and side walls, thereby defining an interior space of the nacelle, wherein the fluid system includes a fluid tank that is integrated into the nacelle cover. The invention extends to a panel of a wind turbine nacelle cover, wherein the panel is configured to define at least apart of, or is coupled to, a fluid tank of a fluid system of the wind turbine.
