A venting cap system includes a first open-ended sleeve and a second open-ended sleeve. The first open-ended sleeve is made from a first material that melts at a selected temperature. The first open-ended sleeve has an internal region commencing at a first end and an externally-threaded region commencing at a second end. The second open-ended sleeve is made from a second material that does not melt at the selected temperature. The second open-ended sleeve is coaxially fitted in the first open-ended sleeve. The second open-ended sleeve includes a first end that is flush with the first end of the first open-ended sleeve. The second open-ended sleeve partially overlaps part of the externally-threaded region. The coefficients of linear expansion of the first material and the second material are about equal.

1. A venting cap system, comprising: a first open-ended sleeve of a first material for melting at a selected temperature, said first open-ended sleeve includes an internal region to commence at a first end thereof and defines a diameter DS, said first open-ended sleeve includes an externally-threaded region to commence at a second end thereof, wherein said externally-threaded region defines a minor diameter DT; and an inner sleeve of a second material being a solid at said selected temperature, wherein said inner sleeve is coaxially fitted in said first open-ended sleeve so that said first open-ended sleeve is bonded to said inner sleeve, wherein said inner sleeve includes a first end flush with said first end of said first open-ended sleeve, wherein said inner sleeve includes a portion, which axially overlaps at least part of said externally-threaded region by an amount L, wherein L<(DT2−DS2)1/2, andwherein said first material and said second material include coefficients of linear expansion that are about equal. 2. The venting cap system as in claim 1, wherein said first material comprises a thermoplastic material. 3. The venting cap system as in claim 1, wherein said first material is selected from the group consisting of polycarbonate, compositions of polycarbonate and glass, nylon, and tetrafluoroethylene. 4. The venting cap system as in claim 1, wherein said second material comprises a metal. 5. The venting cap system as in claim 1, wherein said first material comprises a thermoplastic material and said second material comprises a metal. 6. The venting cap system as in claim 1, wherein said first material comprises a composition of polycarbonate and glass and said second material comprises aluminum. 7. The venting cap system as in claim 1, wherein said amount L comprises a maximum value satisfying L<(DT−DS2)1/2. 8. The venting cap system as in claim 1, wherein said inner sleeve includes an internally-threaded region, which commences at said first end thereof. 9. The venting cap system as in claim 1, wherein at least a portion of external surfaces of said inner sleeve comprise knurled surfaces. 10. The venting cap system as in claim 1, wherein said first open-ended sleeve defines a tapered external region situated between said first end thereof and said externally-threaded region thereof. 11. A venting cap system, comprising: a first open-ended sleeve of a thermoplastic material for melting at a selected temperature, said first open-ended sleeve includes an internal region commencing at a first end thereof and defines a diameter DS, said first open-ended sleeve includes an externally-threaded region to commence at a second end thereof where said externally-threaded region defines a minor diameter DT; andan inner sleeve of a metal being a solid at said selected temperature, wherein said inner sleeve is coaxially fitted said first open-ended sleeve so that said first-open-ended sleeve is bonded to said inner sleeve, wherein said inner sleeve includes a first end flush with said first end of said first open-ended sleeve, wherein said inner sleeve includes a portion axially, which overlaps at least part of said externally-threaded region by an amount L, wherein L is a maximum value satisfying L<(DT2−DS2)1/2, andwherein said first material and said second material include coefficients of linear expansion that are about equal. 12. The venting cap system as in claim 11, wherein said thermoplastic material is selected from the group consisting of polycarbonate, compositions of polycarbonate and glass, nylon, and tetrafluoroethylene. 13. The venting cap system as in claim 11, wherein said thermoplastic material comprises a composition of polycarbonate and glass, and wherein said metal comprises aluminum. 14. The venting cap system as in claim 11, wherein said inner sleeve includes an internally-threaded region to commence at said first end thereof. 15. The venting cap system as in claim 11, wherein at least a portion of external surfaces of said inner sleeve comprise knurled surfaces. 16. The venting cap system as in claim 11, wherein said first open-ended sleeve defines a tapered external region between said first end thereof and said externally-threaded region thereof. 17. A venting cap system, comprising: a first open-ended sleeve of a first material for melting at a selected temperature, said first open-ended sleeve includes an internal region to commence at a first end thereof and defines a diameter DS, said first open-ended sleeve includes an externally-threaded region to commence at a second end thereof where said externally-threaded region defines a minor diameter DT; andan inner sleeve of a second material being solid at said selected temperature, wherein said inner sleeve is coaxially fitted in said first open-ended sleeve with at least a portion of external surfaces of said inner sleeve being knurled for engagement with said first open-ended sleeve so that said first-open-ended sleeve is bonded to said inner sleeve, wherein said inner sleeve includes a first end flush with said first end of said first open-ended sleeve, wherein said inner sleeve includes an internally-threaded region to commence at said first end thereof, and wherein said inner sleeve includes a portion axially, which overlaps at least part of said externally-threaded region by an amount L, wherein L<(DT2−DS2)1/2, andwherein said first material and said second material include coefficients of linear expansion that are about equal. 18.
