Claims26
A method for forming a tubing assembly comprising:
- selecting a fitting having first end and a second end, a first flange closer to the first end than the second end, a second flange closer to the second end than the first end, and a locating feature located axially between the first and second flanges;
- inserting the first end into a first tubing until said first tubing abuts said first flange;
- inserting the second end into a second tubing until said second tubing abuts said second flange;
- placing said fitting into a mold aligning said locating feature with a locating feature within the mold, wherein after said placing, at least a portion of said fitting extending from the first flange to the second flange and said first and second flanges are within said mold;
- and
- molding within said mold a first overmold over the first tubing and over the fitting;
- and
- molding within said mold a second overmold over the second tubing and over the fitting, wherein the first and second overmolds define an overmold section extending from over the first tubing to over the second tubing, and wherein said overmold section is penetrated at least partly by at least one said locating feature of said fitting and said locating feature of said mold prior to removing the fitting and first and second tubings from said mold.

A method for forming tubing assembly comprising:
- selecting a fitting having a body having a first portion having a first end and a second end, and a second portion extending from the first portion between the first and second ends defining a third end, a first flange extending from the first and the second portion and being closer to the first end than the second end, a second flange extending from the first and the second portion and being closer to the second end than the first end, and a locating feature;
- inserting the first end into a first tubing until said first tubing abuts said first flange;
- inserting the second end into a second tubing until said second tubing abuts said second flange;
- placing said fitting into a mold aligning said locating feature with a locating feature within the mold, wherein after said placing, at least a portion of said fitting extending from the first flange to the second flange and said first and second flanges are within said mold;
- and
- molding within said mold a first overmold over the first tubing and over the fitting;
- and
- molding within said mold a second overmold over the second tubing and over the fitting, wherein the first and second overmolds define an overmold section extending from over the first tubing to over the second tubing.
