Abstract

An adaptive fitting for valves. The adaptive fitting has a fitting body having a first end and a second end. The fitting body defines an inner passageway extending from the first end of the fitting to the second end. The fitting is provided with a valve-engaging portion disposed on the first end of the fitting body. This valve-engaging portion has a threaded region for threadably engaging a threaded section of a valve. On the second end of the fitting body is disposed a sealing portion. The fitting is provided with one or more ports disposed about or near the first end of the fitting body for allowing flow there through.

Claims

1. An adapter comprising:

a substantially hollow member having an outer surface, a posterior inner shaft having a posterior inner diameter and an anterior inner surface having an anterior inner diameter;

an anterior inner threaded surface extending at least a portion of the anterior inner surface;

an anterior outer threaded surface extending about at least a portion of the anterior inner surface;

a posterior sealing portion; and

one or more ports positioned on the hollow member for allowing flow from the inner surface to the outer surface.

2. The adapter according to claim 1 further comprising a backflow preventer for preventing flow from returning through the posterior sealing portion.

3. The adapter according to claim 2 wherein the backflow preventer further comprises a threaded portion for threadedly engaging with the anterior inner threaded surface.

4. The adapter according to claim 1 wherein the posterior sealing portion further comprises a gasket.

5. The adapter according to claim 1 wherein the anterior outer threaded surface further comprises an anterior gasket for sealingly engaging with a faucet head.

6. An adaptive fitting for connecting a valve to a water hydrant, the fitting comprising:

a fitting body having a first end and a second end, the fitting body defining an inner passageway extending from the first end to the second end;

a valve engaging portion disposed on the first end of the fitting body, the valve engaging portion having a threaded region for threadably engaging a threaded set of a valve;

a sealing portion disposed on the second end of the fitting body; and

one or more ports disposed about or near the first end of the fitting body for allowing flow there through.

7. The fitting according to claim 6 further comprising a backflow preventer for preventing flow from returning through the sealing portion.

8. The fitting according to claim 7 wherein the backflow preventer further comprises a threaded portion for threadedly engaging with the valve engaging portion.

9. The fitting according to claim 6 wherein the sealing portion further comprises a gasket.

10. The fitting according to claim 6 wherein the first end further comprises a hydrant engaging portion for securing the fitting to a hydrant.

11. The fitting according to claim 10 wherein the hydrant engaging portion further comprises a gasket for sealingly engaging with a faucet head.
