## 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. 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;
the abrasion-resistant middle layer is an elongated strip wrapped 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 terminating 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 2 (depends on 1)

The abrasion-resistant braided hose of claim 1 wherein:
the abrasion-resistant middle layer is made of polytetrafluoroethylene.

### Claim 3 (depends on 1)

The abrasion-resistant braided hose of claim 1 wherein:
said elongated strip has a gap located between edges of the strip to allow for bending of the inner hose.

### Claim 4 (depends on 1)

The abrasion-resistant braided hose of claim 1 wherein:
said elongated strip having a thickness and width that prevents the elongated strip from conforming to any convolution spaces located on the inner hose.

### Claim 5 (depends on 1)

The abrasion-resistant braided hose of claim 1 further comprising:
inner rings connected to the ends of the inner hose.

### Claim 6 (depends on 1)

The abrasion-resistant braided hose of claim 1 further comprising:
braid rings connected to the ends of the braided covering.

### Claim 7 (depends on 1)

The abrasion-resistant braided hose of claim 1 further comprising:
end fittings secured to the ends of the abrasion-resistant braided hose.

### Claim 8

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;
the abrasion-resistant middle layer is an elongated strip wrapped around the inner hose;
said elongated strip has a gap located between edges of the strip to allow for bending of 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 terminating 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 9 (depends on 8)

The abrasion-resistant braided hose of claim 8 wherein:
the abrasion-resistant middle layer is made of polytetrafluoroethylene.

### Claim 10 (depends on 8)

The abrasion-resistant braided hose of claim 8 wherein:
said elongated strip having a thickness and width that prevents the elongated strip from conforming to any convolution spaces located on the inner hose.

### Claim 11 (depends on 8)

The abrasion-resistant braided hose of claim 8 further comprising:
inner rings connected to the ends of the inner hose.

### Claim 12 (depends on 8)

The abrasion-resistant braided hose of claim 8 further comprising:
braid rings connected to the ends of the braided covering.

### Claim 13 (depends on 8)

The abrasion-resistant braided hose of claim 8 further comprising:
end fittings secured to the ends of the abrasion-resistant braided hose.

### Claim 14

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;
the abrasion-resistant middle layer is an elongated strip wrapped in a spiral pattern around the inner hose;
said elongated strip wrapped in a spiral pattern around the inner hose has a gap located between edges of the strip to allow for bending of 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 terminating 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 15 (depends on 14)

The abrasion-resistant braided hose of claim 14 wherein:
said elongated strip having a thickness and width that prevents the elongated strip from conforming to any convolution spaces located on the inner hose.

### Claim 16 (depends on 14)

The abrasion-resistant braided hose of claim 14 wherein:
the abrasion-resistant middle layer is made of polytetrafluoroethylene.

### Claim 17 (depends on 14)

The abrasion-resistant braided hose of claim 14 further comprising:
inner rings connected to the ends of the inner hose.

### Claim 18 (depends on 14)

The abrasion-resistant braided hose of claim 14 further comprising:
braid rings connected to the ends of the braided covering.

### Claim 19 (depends on 14)

The abrasion-resistant braided hose of claim 14 further comprising:
end fittings secured to the ends of the abrasion-resistant braided hose.
