Abstract
Disclosed herein is a hose connector assembly including a hose having a wall defining a lumen and having a first end, and a grommet molded to the hose at the first end and having an annular wall surrounding the hose and spaced therefrom by an annular gap. An insertion surface extends axially along the annular wall from an inner end to an outer end, and a return surface extends from the inner end to a bottom surface of the annular wall.
Claims19
A hose connector assembly comprising:
- a hose having a wall defining a lumen and having a first end;
- and
- a grommet molded to the hose at the first end and having an annular wall surrounding the hose and spaced therefrom by an annular gap, an insertion surface extends axially along the annular wall and terminates in an outer end;
- and
- wherein the grommet is of a different material from the hose.

A grommet comprising:
- an annular wall defining a through hole into a first cylindrical chamber having a first inner diameter, a second cylindrical chamber extends coaxially from the first cylindrical chamber and has a second inner diameter smaller than the first inner diameter, and a tube extends coaxially from the second cylindrical chamber and has a third inner diameter smaller than the second inner diameter;
- and
- wherein the annular wall has a peripheral edge and a sealing rim extending axially toward the outer end.
A method for forming a hose connector assembly comprising:
- providing a hose having a first wall of a first material defining a lumen and having a first end;
- providing a mold for forming a grommet;
- positioning the first end into the mold;
- delivering a flowable flexible second material different from the first material into the mold to form a grommet in securement with the hose;
- and,
- wherein the grommet has a second wall surrounding the hose and spaced therefrom by a gap.
