Abstract
A high pressure hose assembly is manufactured wherein the nipple of the hose fitting includes an O-ring receiving groove formed about its periphery. The O-ring and groove are dimensioned so that the crimping of the fitting's outer sleeve causes the linear of the high pressure hose to flow into the groove, comprising the O-ring into the groove, and sealing against the O-ring within the groove.
