Abstract
A fuel filter nipple with a sleeve portion that fits directly into a fuel filter housing. One flange abuts and is brazed onto the housing. The nipple is formed of a tubular member with longitudinally spaced openings, one of which is larger than the other. One end of the sleeve portion defines the first opening, while the other end of it forms the flange which abuts the housing. The tubular member has a body portion extending from the flange to the other opening, as well as another flange located somewhere along the body portion.
Claims10
A fuel filter nipple, comprising:
- a tubular member having opposite ends and being open at its opposite ends and having an enlarged diameter sleeve portion at one and a smaller diameter body portion extending from the sleeve portion to the other end of the tubular member, the sleeve portion being at least externally tapered;
- first annular flange means on the sleeve portion;
- and said taper extending from at least adjacent said first annular flange means to said one end with the external diameter at said one end being less than the external diameter adjacent said first annular flange and
- second annular flange means on the body portion.
A fuel filter nipple, comprising:
- a tubular member having opposite ends and being open at its opposite ends and having an enlarged diameter sleeve portion at one end and a smaller diameter body portion having a midpoint, the body portion extending from the sleeve portion to the other end of the tubular member, the sleeve portion being at least externally tapered;
- a first annular flange on the sleeve portion;
- said taper extending from at least adjacent said first annular flange means to said one end with the external diameter at said one end being less than the external diameter adjacent said first flange;
- a second annular flange between the first flange and the midpoint;
- and
- a region on the tubular member which is curved inwardly from the first flange to the body portion.
A fuel filter nipple for use with a fuel filter housing, the fuel filter nipple comprising:
- a tubular member having opposite ends and being open at its opposite ends and having an enlarged diameter sleeve portion at one end, the sleeve portion matingly receivable within a larger diameter opening in the housing, the tubular member having a body portion extending from the sleeve portion to the other end of the tubular member;
- first annular flange means on the sleeve portion;
- and
- sole annular flange means on the body portion.
A fuel filter nipple for use with a housing for a fuel filter, the fuel filter nipple comprising:
- a metal tubular member having opposite ends and being open at its opposite ends and having an enlarged diameter sleeve portion at one end, the sleeve portion matingly receivable with the housing, the tubular member having a smaller diameter body portion having a midpoint, the body portion extending from the sleeve portion to the other end of the tubular member, the sleeve portion being at least externally tapered;
- a first annular flange on the sleeve portion, the first flange being brazed to the housing;
- said taper extending from at least adjacent said first annular flange means to said one end with the external diameter at said one end being less than the external diameter adjacent said first annular flange;
- a second annular flange located between the first flange and the midpoint;
- and
- a region on the tubular member which is curved inwardly from the first flange to the body portion.
