ABSTRACT:
A flexible pipe coupling having first and second member rotatable relative to one another. The first member defines national pipe taper, or NPT, threads and the second member includes an internal swag member for forming a swagged connection with a flexible pipe. The coupling can be swagged fitted with respect to an end of a fluid transfer pipe having an inner or primary hose and an outer or secondary hose. The swaged connection can be made with the primary hose. The outside diameter of the coupling can be substantially the same as the outside diameter of the secondary hose so that the coupling can be passed through an entry boot of a sump disposed under a fuel dispenser.
