## Abstract

One variation may include a telescoping pipe which may be retracted or stretched.

## Claims

### Claim 1

A product comprising:
a telescoping pipe comprising:
a first pipe and a second pipe, wherein the second pipe is slideably coupled to the first pipe;
a first O-ring coupled between the first pipe and the second pipe; and
a second O-ring coupled to an inner surface of the second pipe.

### Claim 2 (depends on 1)

The product of claim 1 wherein the second pipe includes a first radial cutout and a second radial cutout and wherein the first radial cutout is constructed and arranged to accommodate the first O-ring and the second radial cutout is constructed and arranged to accommodate the second O-ring.

### Claim 3 (depends on 1)

The product of claim 1 wherein the first O-ring is constructed and arranged to seal the first pipe with the second pipe.

### Claim 4 (depends on 1)

The product of claim 1 wherein the second O-ring is constructed and arranged to seal the second pipe with a mating component.

### Claim 5 (depends on 1)

The product of claim 1 wherein the telescoping pipe is constructed and arranged to transport a fluid.

### Claim 6 (depends on 5)

The product of claim 5 wherein the fluid comprises oil.

### Claim 7 (depends on 1)

The product of claim 1 wherein the second pipe is constructed and arranged to retract and stretch along the first pipe.

### Claim 8 (depends on 1)

The product of claim 1 wherein the second end of the telescoping pipe includes one or more locking features.

### Claim 9 (depends on 8)

The product of claim 8 wherein the one or more locking features are constructed and arranged to lock the telescoping pipe to a mating component.

### Claim 10 (depends on 1)

The product of claim 1 wherein the first pipe has a greater length than the second pipe.

### Claim 11 (depends on 1)

The product of claim 1 wherein the first pipe comprises a first end, a body, a second end, an inner surface, and an outer surface, wherein the first end comprises a first cylindrical surface, a second cylindrical surface, a tapered surface, and a lip extending between the tapered surface and the second cylindrical surface.

### Claim 12 (depends on 11)

The product of claim 11 wherein the first end includes an inward taper.

### Claim 13 (depends on 11)

The product of claim 11 wherein the second end includes an inward taper.

### Claim 14 (depends on 1)

The product of claim 1 wherein the second pipe includes a first end, a second end, an inner surface, and an outer surface;
wherein the inner surface includes a first inner cylindrical surface and a second inner cylindrical surface; and
wherein a first end of the first inner cylindrical surface includes the first radial cutout and a second end of the first cylindrical surface includes the second radial cutout.

### Claim 15 (depends on 14)

The product of claim 14 wherein the second end of the inner surface includes a tapered surface which extends toward the second inner cylindrical surface.

### Claim 16 (depends on 14)

The product of claim 14 wherein the outer surface comprises a first outer cylindrical surface, a second outer cylindrical surface, and a third outer cylindrical surface, wherein a first lip extends approximately vertical between the first outer cylindrical surface and the second outer cylindrical surface and a second lip extends approximately vertical between the second outer cylindrical surface and the third outer cylindrical surface.

### Claim 17 (depends on 16)

The product of claim 16 wherein the diameter of the third outer cylindrical surface is larger than the first and second cylindrical surfaces and the first outer cylindrical surface is greater than the second outer cylindrical surface.

### Claim 18 (depends on 1)

The product of claim 1 further comprising an engine block and an oil cooler, wherein the telescoping pipe transports fluid from the engine block to the oil cooler.

### Claim 19 (depends on 1)

The product of claim 1 wherein the telescoping pipe comprises aluminum.
