Abstract

A plumbing fixture includes a plumbing fixture body having a composition of, by weight percentage, 58-63 of copper, 0.8-1.5 of bismuth, 0.05-0.15 of phosphorous, and a remainder of zinc and any impurities. The plumbing fixture body includes a first opening and a second opening that are arranged to communicate a fluid there through. The first opening defines a first inner diameter D 1 and the second opening defines a second inner diameter D 2 such that a ratio of D 1 /D 2 is 1.05-2.3.

Claims (19)

1. A plumbing fixture comprising:

a plumbing fixture body including a composition by weight percentage of:

58-63 of copper,

0.8-1.5 of bismuth,

0.05-0.15 of phosphorous, and

a remainder of zinc and any impurities,

the plumbing fixture body including a first opening and a second opening arranged to communicate a fluid there through, the first opening defining a first inner diameter D 1 and the second opening defining a second inner diameter D 2 such that a ratio of D 1 /D 2 (D 1 divided by D 2 ) is 1.05-2.3.

2. The plumbing fixture as recited in claim 1 , wherein at least one of the first opening or the second opening has a threaded outer diameter.

3. The plumbing fixture as recited in claim 1 , wherein at least one of the first opening or the second opening has a threaded inner diameter.

4. The plumbing fixture as recited in claim 1 , including a valve member within the plumbing fixture body, the valve member being operable to control communication of fluid between the first opening the second opening.

5. The plumbing fixture as recited in claim 1 , wherein the ratio is 1.1-2.1.

6. The plumbing fixture as recited in claim 5 , wherein the ratio is 1.62-1.65.

7. The plumbing fixture as recited in claim 1 , wherein the ratio is 1.05-1.6.

8. The plumbing fixture as recited in claim 7 , wherein the ratio is 1.08-1.10.

9. The plumbing fixture as recited in claim 1 , wherein the first opening and the second opening are non-coaxially arranged.

10. The plumbing fixture as recited in claim 1 , wherein the first opening and the second opening are coaxially arranged.

11. The plumbing fixture as recited in claim 1 , wherein the plumbing fixture body includes a third opening having a valve actuator located therein.

12. The plumbing fixture as recited in claim 11 , wherein the third opening is coaxially arranged with the first opening and non-coaxially arranged with the second opening.

13. The plumbing fixture as recited in claim 11 , wherein the third opening defines an inner diameter D 3 that is non-equivalent to the first inner diameter D 1 and the second inner diameter D 2 .
