Abstract
Abstract A metal gasket for a face-seal fitting has an outer section in the form of a circular annulus, an inner section in the form of a circular annulus and having a shorter axial dimension than the outer section. The inner section and outer sections are joined by a tapered section having conical faces on opposite sides thereof facing toward the axis of the gasket. A method of prolonging the useful life of a tubular element in a face seal fitting involves repeatedly engaging an end of the tubular element with the conical face and, when the end of the tubular element wears, engaging the end with a radial face adjacent to the conical face.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
100 words
A gasket comprising an outer section in the form of a circular annulus defining a central axis, an inner section in the form of a circular annular concentric with the annulus of said outer section and having an axial dimension shorter than the axial dimension of said outer section, a tapered section connecting said outer section with said inner section, said tapered section having conical faces directed inwardly toward the axis of said circular annuluses, wherein said outer section has faces perpendicular to said central axis, and said axial dimension of said outer section is constant throughout said outer section.
Claim 2
Dependent Claim
100 words
A gasket comprising an outer section in the form of a circular annulus defining a central axis, an inner section in the form of a circular annular concentric with the annulus of said outer section and having an axial dimension shorter than the axial dimension of said outer section, a tapered section connecting said outer section with said inner section, said tapered section having conical faces directed inwardly toward the axis of said circular annuluses, wherein said outer section has faces perpendicular to said central axis, and said axial dimension of said outer section is constant throughout said outer section.
Claim 3
Dependent Claim
13 words
A gasket as recited in claim 1, wherein said conical faces are symmetrical.
Claim 4
Dependent Claim
26 words
A gasket as recited in claim 2, wherein said conical faces are tapered at an angle of about 43 degrees to the axis of said gasket.
Claim 5
Independent Claim
94 words
A method of prolonging the useful life of a tubular element in a face seal fitting comprising providing a gasket with a conical surface adapted to engage the end of said tubular element in said face seal fitting and with a radial surface adjacent to said conical surface, repeatedly engaging said end of said tubular element with said conical surface in a sealing engagement, and when the end of said tubular element wears after repeated remakes of said sealing engagement, engaging said end of said tubular element in sealing engagement with said radial surface.
Claim 6
Independent Claim
94 words
A method of prolonging the useful life of a tubular element in a face seal fitting comprising providing a gasket with a conical surface adapted to engage the end of said tubular element in said face seal fitting and with a radial surface adjacent to said conical surface, repeatedly engaging said end of said tubular element with said conical surface in a sealing engagement, and when the end of said tubular element wears after repeated remakes of said sealing engagement, engaging said end of said tubular element in sealing engagement with said radial surface.
Claim 7
Dependent Claim
165 words
A face seal fitting, comprising: a first tubular element having a first annular end formation; a second tubular element having a second annular end formation; and a gasket including an outer section in the form of an annulus having a first axial dimension, an inner section in the form of an annulus concentric with the annulus of said outer section, said inner section having a second axial dimension shorter than said first axial dimension, and a tapered section connecting said outer section with said inner section, said tapered section defining two bevel faces directed away from one another and inwardly toward the axis of said annuluses, wherein said first annular end formation engages one of said bevel faces in a first region, and said second annular end formation engages the outer of said bevel faces in a second region, and the axial distances between the first and second regions of engagement is at least as great as said second axial dimension of said inner section.
Claim 8
Dependent Claim
165 words
A face seal fitting, comprising: a first tubular element having a first annular end formation; a second tubular element having a second annular end formation; and a gasket including an outer section in the form of an annulus having a first axial dimension, an inner section in the form of an annulus concentric with the annulus of said outer section, said inner section having a second axial dimension shorter than said first axial dimension, and a tapered section connecting said outer section with said inner section, said tapered section defining two bevel faces directed away from one another and inwardly toward the axis of said annuluses, wherein said first annular end formation engages one of said bevel faces in a first region, and said second annular end formation engages the outer of said bevel faces in a second region, and the axial distances between the first and second regions of engagement is at least as great as said second axial dimension of said inner section.
Claim 9
Dependent Claim
13 words
The face seal fitting according to claim 5, wherein the faces are conical.
Claim 10
Dependent Claim
18 words
The face seal fitting of claim 5, wherein said bevel faces are in axial alignment with one another.
Claim 11
Dependent Claim
26 words
The face seal fitting of claim 5, wherein each of said bevel faces defines an angle of about 43 degrees with the axis of said gasket.
Claim 12
Dependent Claim
14 words
The face seal gasket of claim 5, wherein said gasket is made of metal.
Claim 13
Dependent Claim
163 words
A face seal fitting, comprising: a first tubular element having a first annular end formation; a second tubular element having a second annular end formation; and a gasket including an outer section in the form of an annulus having a first axial dimension, an inner section in the form of an annulus concentric with the annulus of said outer section, said inner section having a second axial dimension shorter than said first axial dimension, and means for aligning said first tubular element with said second tubular element, said aligning means comprising a tapered section connection said outer section with said inner section, said tapered section defining two bevel faces directed away from one another and inwardly toward the axis of aid annuluses, wherein said first annular end formation engages one of said bevel faces in a region spaced from said inner section, and said second annular end formation engages the other of said bevel faces in a region spaced from said inner section.
Claim 14
Dependent Claim
163 words
A face seal fitting, comprising: a first tubular element having a first annular end formation; a second tubular element having a second annular end formation; and a gasket including an outer section in the form of an annulus having a first axial dimension, an inner section in the form of an annulus concentric with the annulus of said outer section, said inner section having a second axial dimension shorter than said first axial dimension, and means for aligning said first tubular element with said second tubular element, said aligning means comprising a tapered section connection said outer section with said inner section, said tapered section defining two bevel faces directed away from one another and inwardly toward the axis of aid annuluses, wherein said first annular end formation engages one of said bevel faces in a region spaced from said inner section, and said second annular end formation engages the other of said bevel faces in a region spaced from said inner section.
