Abstract
An example fitting includes: a shell; a nipple disposed within the shell such that an internal annular space is formed between the shell and the nipple; and a sealing sleeve disposed in the internal annular space, wherein the sealing sleeve has a generally cylindrical shape and is made of a flexible material, wherein an annular space is formed between the sealing sleeve and the nipple to receive a hose in the annular space, allowing the sealing sleeve to form a sealed connection with the hose upon crimping the shell onto the hose.
Claims20
A fitting comprising:
- a shell having at least one internal groove;
- a nipple disposed within the shell such that an internal annular space is formed between the shell and the nipple;
- and
- a sealing sleeve disposed in the internal annular space, wherein the sealing sleeve has a generally cylindrical shape and is made of a flexible material, wherein the sealing sleeve has at least one ridge such that as the sealing sleeve is inserted into the shell, the at least one ridge interacts with the at least one internal groove to retain the sealing sleeve within the shell, wherein an annular space is formed between the sealing sleeve and the nipple to receive a hose in the annular space, allowing the sealing sleeve to form a sealed connection with the hose upon crimping the shell onto the hose.

An assembly comprising:
- a fitting comprising:
- (i) a shell having at least one internal groove, (ii) a nipple disposed within the shell such that an internal annular space is formed between the shell and the nipple, and (iii) a sealing sleeve disposed in the internal annular space, wherein the sealing sleeve has a generally cylindrical shape and is made of a flexible material, wherein the sealing sleeve has at least one ridge such that as the sealing sleeve is inserted into the shell, the at least one ridge interacts with the at least one internal groove to retain the sealing sleeve within the shell, wherein an annular space is formed between the sealing sleeve and the nipple;
- and
- a hose inserted into the annular space, allowing the sealing sleeve to form a sealed connection with the hose upon crimping the shell onto the hose.

A method comprising:
- providing a fitting comprising:
- (i) a shell, and (ii) a nipple disposed within the shell such that an internal annular space is formed between the shell and the nipple, wherein the shell has at least one internal groove;
- inserting a sealing sleeve in the internal annular space or mounting the sealing sleeve to a hose, wherein the sealing sleeve has a generally cylindrical shape and is made of a flexible material, wherein the sealing sleeve has at least one ridge, wherein inserting the sealing sleeve into the internal annular space comprises causing the at least one ridge to interact with the at least one internal groove to retain the sealing sleeve within the shell, wherein an annular space is formed between the sealing sleeve and the nipple;
- inserting the hose into the annular space such that the sealing sleeve is radially interposed between the hose and the shell;
- and
- crimping the shell onto the hose, thereby allowing the sealing sleeve to form a sealed connection with the hose.
