Abstract
Abstract A seal for use in an underwater connector having first and second mating members each of which has a coacting mating surface with a plurality of fluid passageways for mating with the passageways of the other member. The seal is a resilient tubular member having threads on a portion of its outer diameter for connection to a passageway on one of the members. The seal includes a fluid sealing surface on its outer end for mating with the other member and the seal includes a fluid sealing surface on its inner end for sealing with the one member. The sealing point of the sealing surface on the outer end has a diameter at least as great as the diameter of the sealing point of the sealing surface on the inner end. The sealing surface on the inner end is formed by an O-ring seal in a groove in the annular resilient seal. The sealing surface on the outer end includes a ridge.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
188 words
In an underwater connector for interconnecting a plurality of fluid lines having first and second mating members, each member having a coacting mating surface with a plurality of fluid passageways for mating with the passageways of the other member, the improvement in seal means on the mating surface of one of the members for sealing between mating passageways of said members comprising, said passageways of said one member having threads, an annular resilient seal having a thread and threadably connected in each of the threaded passageways on said one member, said annular resilient seal having a bore therethrough, said seal including a raised sealing surface on its outer end for mating with the other member, said seal including a raised fluid sealing surface on its inner end for sealing with said one member, the center of the sealing surface on the outer end having a diameter at least as great as the diameter of the center of the sealing surface on the inner end whereby the fluid pressure in the passageways acts on the seals to prevent the fluid pressure from expelling the seals from said one member.
Claim 2
Dependent Claim
188 words
In an underwater connector for interconnecting a plurality of fluid lines having first and second mating members, each member having a coacting mating surface with a plurality of fluid passageways for mating with the passageways of the other member, the improvement in seal means on the mating surface of one of the members for sealing between mating passageways of said members comprising, said passageways of said one member having threads, an annular resilient seal having a thread and threadably connected in each of the threaded passageways on said one member, said annular resilient seal having a bore therethrough, said seal including a raised sealing surface on its outer end for mating with the other member, said seal including a raised fluid sealing surface on its inner end for sealing with said one member, the center of the sealing surface on the outer end having a diameter at least as great as the diameter of the center of the sealing surface on the inner end whereby the fluid pressure in the passageways acts on the seals to prevent the fluid pressure from expelling the seals from said one member.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein the center of the sealing surface on the outer end has a diameter greater than the diameter of the center of the sealing surface on the inner end.
Claim 4
Dependent Claim
27 words
The apparatus of claim 1 wherein the sealing surface on the inner end is formed by an O-ring seal in a groove in the annular resilient seal.
Claim 5
Dependent Claim
11 words
The apparatus of claim 1 wherein the annular seal is polyurethane.
Claim 6
Dependent Claim
44 words
The apparatus of claim 1 wherein the thread on the seal is intermediate the outer end and the inner end of the seal and the outer diameter of the outer end and the inner end is supported by the passageway for preventing outward expansion.
Claim 7
Dependent Claim
34 words
The apparatus of claim 1 wherein the sealing surface on the outer end includes a ridge extending outwardly from the outer end of the seal which is narrower than the thickness of the seal.
Claim 8
Dependent Claim
178 words
A seal for use in an underwater connector having first and second mating members each of which has a coacting mating surface with a plurality of fluid passageways for mating with the passageways of the other member, the passageways of one of the members having threads, comprising, a resilient tubular seal, said seal having a bore therethrough, said seal including threads on a portion of its outer diameter for connection to a threaded passageway on said one member, said seal including a raised fluid sealing surface on its outer end for mating with the other member, said seal including a raised fluid sealing on its inner end for sealing with said one member, and the center of the sealing surface on the outer end has a diameter at least as great as the diameter of the center of the sealing surface on the inner end whereby when the seal is threaded in said one member pressure in the bore of the seal acts on the seal to prevent the pressure from expelling the seal from said one member.
Claim 9
Dependent Claim
178 words
A seal for use in an underwater connector having first and second mating members each of which has a coacting mating surface with a plurality of fluid passageways for mating with the passageways of the other member, the passageways of one of the members having threads, comprising, a resilient tubular seal, said seal having a bore therethrough, said seal including threads on a portion of its outer diameter for connection to a threaded passageway on said one member, said seal including a raised fluid sealing surface on its outer end for mating with the other member, said seal including a raised fluid sealing on its inner end for sealing with said one member, and the center of the sealing surface on the outer end has a diameter at least as great as the diameter of the center of the sealing surface on the inner end whereby when the seal is threaded in said one member pressure in the bore of the seal acts on the seal to prevent the pressure from expelling the seal from said one member.
Claim 10
Dependent Claim
34 words
The apparatus of claim 7 wherein the center of the sealing surface on the outer end has a diameter greater than the diameter of the center of the sealing surface on the inner end.
Claim 11
Dependent Claim
27 words
The apparatus of claim 8 wherein the sealing surface on the inner end is formed by an O-ring seal in a groove in the annular resilient seal.
Claim 12
Dependent Claim
25 words
The apparatus of claim 9 wherein the sealing surface on the outer end includes a ridge extending outwardly from the outer end of the seal.
Claim 13
Dependent Claim
48 words
The apparatus of claim 10 wherein the thread on the seal is intermediate the outer end and the inner end of the seal and the outer diameter of the outer end and the inner end is adapted to be supported by said one member for preventing outward expansion.
Claim 14
Dependent Claim
11 words
The apparatus of claim 11 wherein the annular seal is polyurethane.
