Abstract
An improved hose coupling gasket in which the standard gasket retaining flange is modified to include an additional sealing bead strategically formed on the upper surface of the flange such as to engage the adjacent surface of the gasket retaining groove in the coupling head. The diameter of this additional sealing bead is such that the point of engagement between the sealing bead and retaining groove corresponds to a gage point where the dimensional accuracy of the retaining groove width is checked in accordance with A.A.R. requirements.
