Abstract
A hose fitting is provided to fluidly couple a hose to a component of a boat engine. The hose fitting includes a lead in portion having a substantially smooth exterior surface, a barbed portion with multiple barbs configured to sealingly engage with an inner liner of the hose, a grip portion with multiple substantially flat grip faces; and a terminating portion configured to couple to the component of the boat engine. The lead in portion, the barbed portion, the grip portion, and the terminating portion collectively define a central flow passage extending through the hose fitting.
Claims9
A hose assembly configured to fluidly couple an oil pump to an oil filter in a boat engine, the hose assembly comprising:
- a hose extending from a first end to a second end, the hose comprising an inner liner fabricated from woven PTFE and having a repetitive weave pattern;
- a first hose fitting situated at the first end and a second hose fitting situated at the second end;
- each hose fitting comprising:
- a lead in portion having a substantially smooth exterior surface;
- a barbed portion comprising a plurality of barbs configured to sealingly engage with the inner liner of the hose;
- a grip portion comprising a plurality of substantially flat grip faces;
- and
- a terminating portion configured to couple to the oil pump or the oil filter;
- wherein the lead in portion, the barbed portion, the grip portion, and the terminating portion collectively define a central flow passage extending through each hose fitting;
- and
- wherein each hose fitting is coupled to the hose with a first clamp and a second clamp such that each of the first clamp and the second clamp spans more than one repetition of the repetitive weave pattern.
A method of assembling a hose assembly used to fluidly couple an oil pump to an oil filter in a boat engine, the method comprising:
- providing a hose extending from a first end to a second end, the hose comprising an inner liner that is coupled to an overbraid and has a repetitive weave pattern;
- positioning a first hose clamp and a second hose clamp over the overbraid such that each of the first clamp and the second clamp spans more than one repetition of the repetitive weave pattern of the inner liner;
- inserting a hose fitting into the first end of the hose, the hose fitting comprising:
- a lead-in portion having a substantially smooth exterior surface;
- a barbed portion comprising a plurality of barbs configured to sealingly engage with the inner liner of the hose;
- a knurled portion configured to inhibit rotation of the hose relative to the hose fitting;
- a grip portion comprising a plurality of substantially flat grip faces;
- and
- a terminating portion configured to couple to the oil pump or the oil filter;
- securing the first hose clamp such that the first hose clamp spans a first section of the hose fitting comprising the barbed portion;
- and
- securing the second hose clamp such that the second hose clamp spans a second section of the hose fitting comprising the barbed portion and the knurled portion.
