A plumbing part in the form of a water delivery device is comprised of a protective liner through which potable water can flow. The protective liner is in the form of one or more lengths of stainless steel tubing and is encased in a casting of a desired material, such as bronze or brass. Fittings required to attach the water delivery device to sinks, bathtubs or other water sources and to allow for insertion of various aerators and other flow devices are also encased in the casting. The various fittings are pre-assembled to the liner prior to casting to ensure a water-tight seal between the liner and the fittings prior to casting.

1. A water delivery apparatus, comprising:an exterior casting formed from molten metal having an inlet at a proximal end and an outlet at a distal end;an interior liner extending from proximate said proximal end to proximate said distal end; anda sleeve attached to said proximal end of said casting
1. A water delivery apparatus, comprising:an exterior casting formed from molten metal having an inlet at a proximal end and an outlet at a distal end;an interior liner extending from proximate said proximal end to proximate said distal end; anda sleeve attached to said proximal end of said casting and placed at least partially over said interior liner proximate said proximal end, said sleeve allowing contraction of said casting relative to said liner during the casting process. 2. The apparatus of claim 1, wherein said liner is comprised of at least one segment of tubing comprised of at least one of stainless steel, copper and any material that meets the NSF requirements for clean drinking water. 3. The apparatus of claim 2, wherein said liner is comprised of at least one fitting attached to an end of said at least one segment of tubing. 4. The apparatus of claim 2, wherein said sleeve extends over a portion of said tubing proximate said proximal end of said casting. 5. The apparatus of claim 4, wherein said sleeve and said tubing are attached to form a water-tight seal therein between. 6. The apparatus of claim 1, wherein said liner and said casting form an annular space therein between along at least a portion of said liner. 7. The apparatus of claim 1, wherein said outlet of said casting is provided with threads for coupling an aerator thereto and a fitting attached at said inlet for attachment to a conventional plumbing fitting. 8. The apparatus of claim 1, wherein said liner is comprised of at least two lengths of tubing and at least one coupling device for interconnecting the at least two lengths. 9. The apparatus of claim 1, having a flange coupled to said liner at a distal end thereof, and a fining attached to said sleeve at a proximal end of said liner. 10. A water delivery apparatus, comprising:an exterior casting formed from molten metal having an inlet at a proximal end and an outlet at a distal end;at least one segment of stainless steel tubing forming a waterway within said casting; andan expansion sleeve attached to said proximal end of said casting and placed at least partially over said at least one segment proximate said inlet, said expansion sleeve allowing contraction of said casting relative to said tubing during the casting process. 11. The apparatus of claim 10, further including at least one fitting attached to an end of said at least one segment of stainless steel tubing. 12. The apparatus of claim 10, wherein said sleeve extends over a portion of said tubing proximate said proximal end of said casting. 13. The apparatus of claim 12, wherein said sleeve and said tubing are attached to form a water-tight seal therein between. 14. The apparatus of claim 10, wherein said tubing and said casting form an annular space therein between along at least a portion of said tubing. 15. The apparatus of claim 10, wherein said outlet of said casting is provided with threads for coupling on aerator thereto and a fitting attached at said inlet for attachment to a conventional plumbing fitting. 16. The apparatus of claim 10, wherein said at least one segment is comprised of at least two lengths of tubing and at least one coupling device for interconnecting the at least two lengths. 17. The apparatus of claim 10, having a flange coupled to said tubing at a distal end thereof, and a fitting attached to said sleeve at a proximal end of said tubing, said fitting configured for attaching to a conventional plumbing fitting. 18. A water delivery apparatus, comprising:an exterior casting having an inlet at a proximal end and an outlet at a distal end;an interior liner extending from proximate said proximal end to proximate said distal end, said liner and said casting forming an annular space therein between along at least a portion of said liner; anda sleeve attached to said proximal end of said casting and placed at least partially over said interior liner proximate said proximal end, said sleeve allowing contraction of said casting relative to said liner during the casting process. 19. The apparatus of claim 18, wherein said exterior casting is formed from molten metal. 20. The apparatus of claim 18, wherein said liner is comprised of at least one segment of tubing comprised of at least one of stainless steel, copper and any material that meets the NSF requirements for clean drinking water. 21. The apparatus of claim 20, wherein said liner is comprised of at least one fitting attached to an end of said at least one segment of tubing. 22. The apparatus of claim 20, wherein said sleeve extends over a portion of said tubing proximate said proximal end of said casting. 23. The apparatus of claim 22, wherein said sleeve and said tubing are attached to form a water-tight seal therein between. 24. The apparatus of claim 18, wherein said outlet of said casting is provided with threads for coupling an aerator thereto and a fitting attached at said inlet for attachment to a conventional plumbing fitting. 25. The apparatus of claim 18, wherein said liner is comprised of at least two lengths of tubing and at least one coupling device for interconnecting the at least two lengths. 26. The apparatus of claim 18, having a flange coupled to said liner at a distal end thereof, and a fitting attached to said sleeve at a proximal end of said liner. 27. A water delivery apparatus, comprising:an exterior casting having an inlet at a proximal end and an outlet at a distal end;at least one segment of stainless steel tubing forming a waterway within said casting; andan expansion sleeve attached to said proximal end of said casting and placed at least partially over said at least one segment proximate said inlet, said expansion sleeve allowing contraction of said casting relative to said liner during the casting process, said at tubing and said casting forming an annular space therein between along at least a portion of said tubing. 28. The apparatus of claim 27, wherein said exterior casting is formed from molten metal. 29. The apparatus of claim 27, further including at least one fitting attached to an end of said at least one segment of stainless steel tubing. 30. The apparatus of claim 27, wherein said sleeve extends over a portion of said tubing proximate said proximal end of said casting. 31. The apparatus of claim 30, wherein said sleeve and said tubing are attached to form a water-tight seal therein between. 32.
