Patent ID: 7503595

Claim:
A fitting for a fluid conduit, comprising: a coupling body having an inside surface for engaging an outside surface of an associated fluid conduit and a shoulder portion for limiting axial insertion of the associated fluid conduit into said coupling body; a proximal seal formed on said inside surface of said coupling body immediately adjacent said shoulder portion, said proximal seal including an inner tooth that transitions directly into a radius, said radius disposed between said inner tooth and said shoulder portion and directly transitioning into said shoulder portion which blends said tooth into said shoulder portion, wherein an axial distance between said proximal seal and said shoulder portion is less than an axial width of said proximal seal; a ring annularly disposed on said coupling body urging said proximal seal into said fluid conduit to seal and mechanically connect said coupling body to the fluid conduit; a main seal formed on said inside surface of said coupling body axially spaced from said proximal seal and said main seal is axially spaced from said proximal seal a distance sufficient to allow said main seal and said proximal seal to form seals and mechanical connections by engaging and deforming the associated fluid conduit without interfering with one another; a main seal land formed on an outside surface of said coupling body opposite said main seal; and proximal seal land formed on said outside surface of said coupling body opposite said proximal seal, said proximal seal land axially spaced apart from said main seal land; wherein each of said main seal land and said proximal seal land include a plateau axially flanked by a pair of ramps and radially spaced relative to said outside surface, said plateau of said main seal land being radially aligned with and having substantially the same diameter as said plateau of said proximal seal land and being axially spaced relative thereto such that adjacent ramps of said main and said proximal seal lands from a recess therebetween.
