Lined water conduit

1 . A water conduit faucet assembly comprising:

a base;

a delivery spout supported by the base and formed of a metallic material, the delivery spout including an outer surface and an inner surface extending between an inlet and an opposing outlet; and

a thermoplastic liner molded within the delivery spout, the thermoplastic liner having an outer surface substantially contacting the inner surface of the delivery spout from the inlet to the outlet.

2 . The water faucet assembly of claim 1 , wherein the thermoplastic liner is formed of a polyethylene.

3 . The water faucet assembly of claim 2 , wherein the thermoplastic liner is formed of a cross-linked polyethylene.

4 . The water faucet assembly of claim 1 , further comprising a plating layer received on the outer surface of the support tube.

5 . (canceled)

6 . A delivery spout for a water faucet assembly, the delivery spout comprising:

an outer cover formed of a metallic material; and

a liner received within the outer cover, the liner being formed of a cross-linked polyethylene.

7 . The delivery spout of claim 6 , wherein the liner is molded within the outer cover.

8 . The delivery spout of claim 7 , wherein the liner is blow molded within the outer cover.

9 . The delivery spout of claim 6 , wherein the linter has an outer surface which contacts the inner surface of the outer cover from the inlet to the outlet.

10 . The delivery spout of claim 6 , further comprising a plating layer received on the outer surface of the outer cover.

11 . A method of forming a water conduit, the method comprising the steps of:

providing a support tube including a first end, a second end, and an inner surface defining a passageway extending between the first end and the second end;

providing a thermoplastic material;

inserting the thermoplastic material within the passageway of the support tube;

heating the thermoplastic material;

placing a tubular member of the thermoplastic material within the passageway of the support tube, the tubular member having a first end and a second end;

sealing the first end of the tubular member with a plug;

sealing the second end of the tubular member with a blow pin assembly;

applying pressurized fluid to the second end of the tubular member; and

cooling the thermoplastic material within the support tube.

12 . The method of claim 11 , wherein the thermoplastic material comprises a polyethylene, and the method further comprises the step of cross-linking the polyethylene.

13 . The method of claim 12 , wherein the cross-linking step includes providing a silane-grafted polyethylene and exposing the silane-grafted polyethylene to moisture and heat.

14 . (canceled)

15 . The method of claim 11 , further comprising the step of metal plating the outer surface of the support tube.

16 . The method of claim 11 , wherein the support tube comprises a delivery spout of a water faucet assembly.

17 . A method of forming a delivery spout for a water faucet assembly, the method comprising the steps of:

providing a metallic support tube including a passageway;

providing a polyethylene material;

inserting the polyethylene material within the passageway of the support tube;

heating the polyethylene material;

molding the polyethylene material within the support tube; and

cross-linking the polyethylene material within the support tube.

18 . The method of claim 17 , wherein the cross-linking steps includes providing a silane-grafted polyethylene and exposing the silane-grated polyethylene to moisture and heat.

19 . The method of claim 17 , wherein the molding step includes placing a tubular member of the polyethylene material within the passageway of the support tube, the tubular member having a first end and a second end, sealing the first end of the tubular member, and applying pressurized fluid to the second end of the tubular member.

20 . The method of claim 17 , further comprising the step of metal plating the outer surface of the support tube.

21 . The water faucet assembly of claim 3 , wherein the thermoplastic liner is cross-linked within the delivery spout.

22 . The water faucet assembly of claim 1 , further comprising a rotatable coupling supporting the delivery spout.
