## Abstract

Systems and methods for extending a valve stem. The systems include an extender, a securing apparatus, a cover, and a handle. The extender is placed on and around the valve stem and the cover over and around the extender. The handle is secured to an upper surface of the extender by the securing apparatus. The methods include configuring the extension onto a valve stem by removing a securing apparatus and a handle and affixing the extender and cover to a lower surface of a valve. The securing apparatus secures the handle to an upper surface of the extender.

## Claims

### Claim 1

A system for extending a valve stem comprising:
an extender;
a cover that covers an outer surf ace of the extender;
a handle that is placed on an upper surface of the extender;
a washer with a tab;
a compression gasket that is affixed to an outer circumference of the extender and inner circumference of the cover, such that the compression gasket is radially in between and in contact on opposing inner and outer sides of the compression gasket with the extender and the cover, wherein the compression gasket is a complete cylindrical tube positioned from a terminal end of the extender over a longitudinal length of the extender such that the compression gasket is configured to be fully circumferentially around the valve stem for the entire longitudinal length when the valve stem extension is positioned on the valve stem and provide insulation to the valve stem; and
a securing apparatus that secures the extender and handle to a valve body.

### Claim 2 (depends on 1)

The system of claim 1, wherein the extender further comprises a first opening that accepts the valve stem.

### Claim 3 (depends on 2)

The system of claim 2, wherein the system further comprises a fastener;
wherein the extender further comprises a second opening that matably interacts with the fastener such that the fastener secures the extender to the valve stem.

### Claim 4 (depends on 3)

The system of claim 3, wherein the washer is placed in between the valve body and the extender and the tab contacts the valve body.

### Claim 5 (depends on 1)

The system of claim 1, wherein an interior surface of the extender is threaded and matably interacts with the valve stem.

### Claim 6 (depends on 1)

The system of claim 1, wherein the securing apparatus is a bolt, a nut, a washer, or a coupling.

### Claim 7 (depends on 1)

The system of claim 1, wherein the handle further comprises an opening.

### Claim 8 (depends on 1)

The system of claim 1, wherein the extender is comprised of brass, steel, carbon steel, stainless steel, or metal.

### Claim 9 (depends on 1)

The system of claim 1, wherein the cover is comprised of nylon.

### Claim 10

A method of extending a valve stem of a valve, comprising:
removing a securing apparatus from a valve;
removing a handle from the valve;
coupling a washer with a tab directly onto a valve stem of the valve;
coupling an extender to the valve stem abutting the washer;
coupling a cover to the extender;
coupling a compression gasket to an outer circumference of the extender and inner circumference of the cover, such that the compression gasket is radially in between and in contact on opposing inner and outer sides of the compression gasket with the extender and the cover; coupling the handle to the extender, wherein the compression gasket is a complete cylindrical tube positioned from a terminal end of the extender over a longitudinal length of the extender such that the compression gasket is configured to be fully circumferentially around the valve stem for the entire longitudinal length when the valve stem extension is positioned on the valve stem and provide insulation to the valve stem; and
coupling the securing apparatus to the extender to secure the handle to the valve.

### Claim 11 (depends on 10)

The method of extending a valve stem of claim 10, further comprising placing the handle on an upper surface of the extender to secure the extender to the valve by the securing apparatus.

### Claim 12 (depends on 11)

The method of extending a valve stem of claim 11, further comprising fastening the extender to the valve stem with a fastener.

### Claim 13 (depends on 11)

The method of extending a valve stem of claim 11, further comprising fastening the extender to the valve stem with a fastener.

### Claim 14 (depends on 11)

The method of extending a valve stem of claim 11, wherein the compression gasket is placed over and around the extender, such that the compression gasket is in between the extender and the cover.
