A metallic hose coupling assembly provides an improved coupling insert for flexible elastomeric hose. The insert contains a series of external barbs defined by repeating asymmetrical, axially inversely oriented pairs of frustoconical segments spaced apart by and contiguous with cylindrical segments positioned therebetween. each mated pair of frustoconical segments interfaces with a cylindrical segment in a manner which defines rounded interface edges having radii which fall within a range of 15 to 25 thousandths of an inch. The latter configuration of barb provides an effective means of preventing fracture of elastomer hose ends when subjected to relatively high pressure hydraulic applications.
