Abstract
The coupling disclosed is for attachment to a loading arm and permits attachment of the loading arm to flanges of different diameters by providing adapters which are releasably secured to the coupler. A different size adapter is utilized for each different size flange that the coupler is to be fastened to. The clamp arms move radially outward from the flowway through the coupler to accommodate larger size adapters which fit with larger size flanges to which the coupling is to be attached.
