## Abstract

An abrasion-resistant braided hose (1) having an abrasion-resistant layer (4) located between an inner hose (2) and a braiding covering (3). The abrasion-resistant layer is preferably a strip of Teflon® helically or spirally wrapped around the inner hose to allow for flexibility or a stripwound interlocking hose. The abrasion-resistant layer reduces the amount of friction between the inner hose and the braided covering, thereby reducing the likelihood of the inner hose rupturing and failing.

## Claims

### Claim 1

An abrasion-resistant braided hose comprising:
an elongated inner hose having two ends;
an outer braided covering surrounding the inner hose;
an abrasion-resistant middle layer located between the braided covering and the inner hose; and
the abrasion-resistant middle layer is a stripwound interlocking hose.

### Claim 2

An abrasion-resistant braided hose comprising:
an elongated inner hose having two ends;
an outer braided covering surrounding the inner hose;
an abrasion-resistant middle layer located between the braided covering and the inner hose; and
the abrasion-resistant middle layer has a coating of lubricant.

### Claim 3

An abrasion-resistant braided hose comprising:
an elongated inner hose having two ends;
an outer braided covering surrounding the inner hose;
an abrasion-resistant middle layer located between the braided covering and the inner hose;
inner rings connected to the ends of the inner hose; and
the abrasion-resistant middle layer located between the braided covering and the inner hose terminates a predetermined distance from the ends of the inner hose to leave space for the inner rings to be connected to the ends of the inner hose.

### Claim 4

An abrasion-resistant braided hose comprising:
an elongated inner having two ends;
an outer braided covering surrounding the inner hose;
an abrasion-resistant middle layer located between the braided covering and the inner hose;
the abrasion-resistant middle layer is an elongated strip of tape wrapped in a spiral pattern around the inner hose; and
the abrasion-resistant middle layer is a stripwound interlocking hose.

### Claim 5

An abrasion-resistant braided hose comprising:
an elongated inner having two ends;
an outer braided covering surrounding the inner hose;
an abrasion-resistant middle layer located between the braided covering and the inner hose;
the abrasion-resistant middle layer is an elongated strip of tape wrapped in a spiral pattern around the inner hose; and
the abrasion-resistant middle layer has a coating of lubricant to further reduce friction between the inner hose and the braided covering.

### Claim 6

An abrasion-resistant braided hose comprising:
an elongated inner having two ends;
an outer braided covering surrounding the inner hose;
an abrasion-resistant middle layer located between the braided covering and the inner hose;
the abrasion-resistant middle layer is an elongated strip of tape wrapped in a spiral pattern around the inner hose;
inner rings connected to the ends of the inner hose; and
the abrasion-resistant middle layer located between the braided covering and the inner hose terminates a predetermined distance from the ends of the inner hose to leave space for the inner rings to be connected to the ends of the inner hose.
