An apparatus for covering or sealing Storz-type outlets is shown and described. The apparatus includes an outer cap portion having a continuous sidewall, a connector portion for connecting the outer cap portion to the water supply assembly and a sealing cap portion rotatably coupled to the outer cap portion and located at least partially within a void defined by the continuous sidewall, the sealing cap portion including a pliable sealing portion for forming a seal about the water supply outlet. The connector portion includes a pair of lugs and a pair of ramped lug guides associated with an inner surface of the continuous sidewall. The pair of ramped lug guides are provided for receiving a pair of lugs of the water supply assembly. A nut portion extends from an outer face of outer cap portion for engagement by a tool such as a wrench or socket for rotating the outer cap portion about the water supply outlet.

1. A method of sealing a fire hydrant comprising, providing an assembly including, a fire hydrant having an outlet, the outlet including a first Storz connecting portion,a cap having a second Storz connecting portion, the second Storz connecting portion being configured for detachably engaging the first Storz connecting portion, anda swivel seal rotatably supported by the cap, the swivel seal including an annular gasket supported substantially about a peripheral portion of the swivel seal, andengaging the second Storz connecting portion with the first Storz connecting portion, followed by,contacting the swivel seal and the annular gasket to the outlet,engaging the nut portion with a tool and rotating the cap about the outlet,wherein the cap is rotated about the outlet with and without rotation of the swivel seal relative to the cap. 2. The method according to claim 1 further comprising providing a nut portion extending from an outer face of the cap, the nut portion being configured for engagement by a tool for rotating the cap about the outlet. 3. The method according to claim 2 further comprising providing a support member extending from an inner face of the cap and rotatably supporting the swivel seal wherein the support is axially aligned with the nut portion. 4. The method according to claim 1 further comprising providing a support member extending from an inner face of the cap and rotatably supporting the swivel seal wherein axial movement of the swivel seal along the support member is restrained. 5. The method according to claim 1 wherein each of the first Storz connecting portion and the second Storz connecting portion includes a pair of lugs. 6. The method according claim 1 wherein each of the first Storz connecting portion and the second Storz connecting portion includes a pair of ramped lug guide channels. 7. The method according to claim 1 wherein the cap includes a continuous sidewall defining a void, the swivel seal being contained entirely within the void. 8. The method according to claim 1 further comprising providing a support member extending from an inner face of the cap and rotatably supporting the swivel seal wherein the swivel seal includes a central opening through which the support member extends and an o-ring located in the central opening. 9. A method of sealing a water supply outlet comprising, providing a cap including a cap portion, a connector portion and a sealing cap portion located at least partially within a void defined by a sidewall of the cap portion,engaging the connector portion with the water supply outlet,contacting a pliable sealing portion supported by the sealing cap portion to the water supply outlet, the pliable sealing portion being an annular gasket supported about a peripheral portion of the sealing cap portion, androtating the cap portion in a first direction without rotating the sealing cap portion,wherein rotating the cap portion draws the sealing cap portion towards the water supply outlet thereby compressing the pliable sealing portion against the water supply outlet and forming a seal about the water supply outlet. 10. The method according to claim 9 wherein engaging the connector portion with the water supply outlet includes inserting a pair of lugs of the connector portion into a pair of ramped lug guides in the water supply outlet. 11. The method according to claim 10 wherein engaging the connector portion with the water supply outlet includes inserting a pair of lugs of the water supply outlet into a pair of ramped lug guides of the connector portion. 12. The method according to claim 9 further comprising engaging a nut portion of the cap portion with a tool and rotating the nut portion to cause rotating of the cap portion. 13. The method according to claim 9 further comprising rotating the cap portion in a second direction thereby uncompressing the pliable sealing portion without rotating the sealing cap portion. 14. The method according to claim 13 further comprising separating the pliable sealing portion from the water supply outlet, followed by rotating the cap portion and the sealing cap portion together in the second direction, followed by disengaging the connector portion from the water supply outlet. 15. A method for sealing a water supply outlet of a water supply assembly comprising, providing an apparatus including, an outer cap portion including a sidewall, a cover having an outer face and an inner face, and a nut portion extending from the outer face of the cover,a connector portion, anda sealing cap portion rotatably coupled to a support member extending from the inner face of the cover, the sealing cap portion being coaxially aligned with the sidewall and including an annular gasket supported substantially about a periphery of the sealing cap portion,engaging the connector portion with the water supply assembly,contacting the annular gasket to the water supply assembly, androtating the outer cap portion in a first direction thereby pressing the gasket against the water supply assembly and forming a seal about the water supply outlet,wherein rotating the outer cap portion does not cause rotating of the sealing cap portion. 16. The method according to claim 15 wherein the connector portion includes a Storz connector. 17. The method according to claim 15 comprising rotating the outer cap portion in a second direction thereby decompressing the annular gasket without rotating the sealing cap portion. 18. The method according to claim 17 further comprising separating the annular gasket from the water supply assembly, followed by rotating the outer cap portion and the sealing cap portion together in the second direction, followed by disengaging the connector portion from the water supply assembly.
