A refuelling coupling has an annular fitting 101 having a bore 102, bayonet lugs 103 and slots 104 suiting it for connection to a pressure filling nozzle. A flange 122, drilled with screw holes for securement to a fuel tank (not shown), extends out from the fitting 101. Also not shown for the sake of clarity is a tube extending own from the flange. Rods extend down from the flange 122 to a spider 125, with springs bearing upwards onto the underside of a dry-break member 105, through which the rods extend. The rods, springs and spider are within the non-shown tube.On attaching and opening of a pressure filling nozzle to the coupling, the dry-break member 105 is displaced resiliently inwards fuel can flow past this member and into the tank.The dry-break member has a central aperture 111, normally closed by a plug 112, which is threaded externally 114 and carries an O-ring seal 115 above the thread. The central aperture has a plain bore orifice 116 and is threaded 117 below the plain bore. Thus, when the plug is screwed in, the dry-break member is fluid tight as normal.
