An integrated seal assembly and a connector incorporating the seal assembly for connecting a coaxial cable to an externally threaded port. The seal assembly includes a bellows-type seal having an elastically deformable tubular body and a plurality of sealing surfaces, and an integral joint-section intermediate an anterior end and a posterior end that assists in the axial deformation of the seal in response to axially-directed force. One of the sealing surfaces is made to engage a corresponding surface of an internally threaded nut. The nut and attached seal form an integral seal assembly. A coaxial cable connector includes a connector body. One end of the body attaches a coaxial cable, the seal assembly being rotatably attached to the other end. The connector is engagable with an externally threaded port via the internally threaded nut component of the connector. The anterior end of the seal fits over the port and a sealing surface of the seal is capable of sealing axially against a shoulder of the port while the seal body covers the otherwise exposed externally threaded port. Upon tightening of the nut on the port, the seal deflects in the axial direction to accommodate a variety of distances between the connector and the shoulder of the port. Additionally, the seal is capable of expanding to allow a second sealing surface to contact and seal against a variety of smooth outside diameters of the port. The versatility of the seal allows an operator to use one connector on a wide variety of externally threaded ports without the risk of a faulty seal at the connection or a poor connection due to an improper seal.

I claim: 1. A connector for connecting a coaxial cable to a port, comprising: a connector body having a first end adapted to accept and retain a coaxial cable and a second end; a nut component having en interior surface adapted to engage the port, a connector grasping portion, and a seal grasping surface portion, said nut component rotatably engaged with the second end of the connector body; and a seal having en elastically deformable body adapted to accommodate different length parts, said deformable body having a posterior sealing surface that cooperatively engages the seal-grasping surface portion of the nut component, a forward sealing surface that cooperatively engages the port and an intermediate section between the posterior sealing surface and forward sealing surface having a reduced cross-sectional thicknessconfigured to promote a radial expansion of the seal upon its axial compression, wherein the seal is attached to the nut component prior to engagement with the port. 2. The connector of claim 1, further comprising a seal ring having an inner surface and an outer surface, said inner surface having a diameter such that the seal ring is press-fit against an exterior surface of the seal that is radially adjacent the posterior sealing surface. 3. The connector of claim 2, wherein the seal ring has an outwardly extending flange along a posterior perimeter of the seal ring. 4. The connector of claim 2, wherein the outer surface of the seal ring Is knurled. 5. The connector of claim 1, wherein at least part of the seal-grasping portion is one of a smooth surface and a roughened surface suitable to frictionally engage the sealing surface of the seal. 6. The connector of claim 5, wherein the seal-grasping portion further comprises a ridge on the exterior surface of the nut component. 7. The seal assembly of claim 5, wherein the seal-grasping portion comprises a groove on the interior surface of The nut component. 8. The connector of claim 1, wherein at least part of the seal-grasping portion is a surface suitable to adhesively engage the sealing surface of the seal. 9. The connector of claim 1, wherein the nut component further includes a nut-turning surface portion along an external perimeter surface of the nut component. 10. The connector of claim 9, wherein the nut-turning surface portion at least two flat surface regions. 11. The connector of claim 9, wherein the nut-turning surface portion is a knurled surface. 12. The connector of claim 1, wherein the seal has an integral joint-section between the posterior sealing surface and the forward sealing surface. 13. The connector of claim 1, wherein the seal has an axial length in an uncompressed state that is sufficient to fully cover the port when the port is in a fully connected relationship with the connector. 14. A method for sealing a coaxial cable connector to a threaded port, comprising the steps of: providing a connector for electrically and mechanically engaging a coaxial cable to a threaded port, said connector comprising: (a) a connector body for attaching the connector to a prepared coaxial cable; (b) a connector post for electrically engaging the outer conductor of the coaxial cable; and (c) a nut component having an interior surface portion adapted to engage the treaded port, said nut component rotatably engaged with the connector post; attaching a seal with an elastically deformable body to the nut component, said seal having a posterior sealing surface for cooperatively engaging the nut component, a forward sealing surface for cooperatively engaging the port and an integral joint-section such that the seal and nut component form an integrated seal assembly; and rotating the integrated seal assembly to engage the interior surface portion of the nut component with the threaded port such that the forward sealing surface of the seal engages the port to form a moisture-resistant barrier between the connector and the port. 15. The method for sealing a connector to a threaded port of claim 14 comprising the additional step of providing a seal ring fit over a portion of the nut component and a posterior portion of the seal. 16. The method for sealing a connector to a threaded port of claim 14 comprising the additional step of advancing the connector onto the post such that the seal radially expands in the vicinity of the universal joint-section. 17. A coaxial cable connector for sealingly connecting a coaxial cable to a port, comprising: a connector body having a first end for receiving a coaxial cable and a second end; a nut component having an interior surface portion adapted to engage a threaded port, an internal shoulder for rotatably engaging the second end of the connector body, and a seal-grasping surface portion; and a seal attached to the nut component, said seal having an elastically deformable body, a posterior sealing surface for cooperatively engaging the seal-grasping surface portion of the nut component, a forward sealing surface for cooperatively engaging the port, and an integral joint-section between the posterior sealing surface and the forward sealing surface. 18. The connector of claim 17, further comprising a seal ring having an inner surface and an outer surface, said inner surface having a diameter such that the seal ring is press-fit against an exterior surface of the seal that is radially adjacent the posterior sealing surface. 19. The connector of claim 18, wherein the seal ring has an outwardly extending flange along a posterior perimeter of the seal ring. 20. The connector of claim 18, wherein the outer surface of the seal ring is knurled.
