Abstract
Abstract A corrosion-resistant sealing member comprising: a relatively rigid cylindrical member, made from a corrosion-resistant material deformable under applied pressure, with a passage connecting its ends, a flange at one end extending outward from its outer periphery, and a groove at the other end extending inward from its outer periphery in a manner such as to provide a thin flexible wall between the groove and the adjacent end of the cylindrical member; a first gasket disposed within the groove; and a second gasket disposed about the cylindrical member abutting the flange, both gaskets being made from materials that are resilient over the range of temperature variation to which they are subjected.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
A corrosion-resistant sealing member, for connecting conduits, comprising: a. a relatively rigid substantially cylindrical member made from a corrosion-resistant material deformable under applied pressure, said substantially cylindrical member having a first flange at one end thereof extending outward from its outer periphery and adapted to mate with a first one of said conduits, a first groove at the other end thereof extending inward from its outer periphery in a manner such as to provide a thin flexible wall between said firSt groove and the end of said substantially cylindrical member associated therewith and adapted to mate with a second one of said conduits, and a passage therethrough connecting both ends of said substantially cylindrical member; b. a first circular gasket disposed within said first groove; and c. a second circular gasket disposed about the outer periphery of said substantially cylindrical member, abutting said first flange, said first and second circular gaskets being made from materials that are resilient over the range of temperature variation to which they are subjected.
Claim 2
Dependent Claim
169 words
A corrosion-resistant sealing member, for connecting conduits, comprising: a. a relatively rigid substantially cylindrical member made from a corrosion-resistant material deformable under applied pressure, said substantially cylindrical member having a first flange at one end thereof extending outward from its outer periphery and adapted to mate with a first one of said conduits, a first groove at the other end thereof extending inward from its outer periphery in a manner such as to provide a thin flexible wall between said firSt groove and the end of said substantially cylindrical member associated therewith and adapted to mate with a second one of said conduits, and a passage therethrough connecting both ends of said substantially cylindrical member; b. a first circular gasket disposed within said first groove; and c. a second circular gasket disposed about the outer periphery of said substantially cylindrical member, abutting said first flange, said first and second circular gaskets being made from materials that are resilient over the range of temperature variation to which they are subjected.
Claim 3
Dependent Claim
17 words
The corrosion-resistant sealing member of claim 1 wherein the material of said substantially cylindrical member is thermoplastic.
Claim 4
Dependent Claim
23 words
The corrosion-resistant sealing member of claim 1 wherein the material from which said substantially cylindrical member is made comprises a polymer of tetrafluoroethylene.
Claim 5
Dependent Claim
25 words
The corrosion-resistant sealing member of claim 1 wherein the material from which said substantially cylindrical member is made comprises a copolymer of tetrafluoroethylene and hexafluoropropylene.
Claim 6
Dependent Claim
29 words
The corrosion-resistant sealing member of claim 1 wherein the material from which said first and second circular gaskets are made has a hardness of between 30 and 60 durometers.
Claim 7
Dependent Claim
41 words
The corrosion-resistant sealing member of claim 1 wherein the material of said substantially cylindrical member is thermoplastic, and wherein the material from which the said first and second circular gaskets are made has a hardness of between 30 and 60 durometers.
Claim 8
Dependent Claim
59 words
The corrosion-resistant sealing member of claim 1 wherein said first flange contains a second groove extending inward from the outer periphery thereof in a manner such as to provide a thin flexible wall between said second groove and the end of said substantially cylindrical member associated therewith, and wherein said second circular gasket is disposed within said second groove.
Claim 9
Dependent Claim
96 words
The corrosion-resistant sealing member of claim 1 wherein said first circular gasket has a width slightly greater than the width of said first groove, whereby, in an uncompressed state, said first circular gasket extends only part of the way to the bottom of said first groove and the wall of said first groove adjacent to the end of said substantially cylindrical member is forced outward from the end of said substantially cylindrical member, thereby allowing compression of said first circular gasket and the formation of a seal before destructive deformation of said substantially cylindrical member occurs.
Claim 10
Dependent Claim
50 words
The corrosion-resistant sealing member of claim 1 wherein said substantially cylindrical member further comprises a second flange, at the end thereof containing said first groove, extending inward from its inner periphery, thereby forming a z-shaped sealing member, and wherein the bottom of said first groove extends into said second flange.
Claim 11
Dependent Claim
77 words
The corrosion-resistant sealing member of claim 9 further comprising a separate split-ring retaining member adapted to mate with the end of said substantially cylindrical member containing said first flange in a manner such as to provide a rim extending from the inner periphery of said substantially cylindrical member, whereby a support groove for supporting a structure within said corrosion resistant sealing member is formed between said second flange and the rim formed by said split-ring retaining member.
