Abstract
A convertible hose connector assembly includes a clamping nut, a crimp sleeve, a hose insert, and a replacement pipe. The crimp sleeve is coupled to the hose insert and the hose insert is coupled to the replacement pipe. The replacement pipe replaces a coupler coupled to a convertible top hydraulic cylinder prior to being remanufactured to produce a remanufactured convertible top hydraulic cylinder. The remanufactured convertible top hydraulic cylinder including at least one of the hose connector assembly.
Claims20
A hose connector assembly comprising:
- an attachment assembly including:
- a pipe having a first end and a second end, the replacement pipe having an internal bore extending therethrough and a retention collar spaced apart from the second end;
- a hose insert positioned at the first end of the pipe, the hose insert having a proximal end and a distal end, and a central bore that corresponds to the internal bore of the pipe, with an outer surface having a pattern disposed thereon;
- a hose insertion member positioned between the pipe and the hose insert having an outer surface, and a second central bore that corresponds to the central bore of the hose insert, the hose insertion member defining a flange at the proximal end of the hose insert;
- a crimping sleeve attachable to the hose insertion member, the crimping sleeve having an end body and a crimp sleeve, the crimp sleeve having an internal bore and an outer surface, the outer surface having a threaded portion and at least one relief slot extends through the crimp sleeve;
- and
- a clamping nut having a bore with a threaded portion interfaceable with the threaded portion of the crimp sleeve, whereupon tightening of the clamping nut directs the inner bore proximate the at least one relief slot toward the outer surface of the hose insert, whereupon a hose portion positioned therebetween can be clamped between the outer surface of the hose insert and the inner bore in sealed engagement.

A hydraulic cylinder comprising:
- a body having at least one port in communication with a cylinder having a rod slidably movable within the cylinder;
- a hose connector assembly including:
- an attachment assembly including:
- a pipe having a first end and a second end, the replacement pipe having an internal bore extending therethrough and a retention collar spaced apart from the second end;
