A gasket loop includes a gasket shape with a first portion characterized by a cross-sectional view. The first portion in the cross-sectional view includes a substantially elongated body characterized by a height, a first end characterized by a height, a tip, a width enlarged relative to the body, and a tapered backside. The tapered backside is integral with the body. The first portion in the cross-sectional view additionally includes a distal second end connected to the body. A fluid-pressure joint assembly and a method of sealing such a joint via the gasket loop are also disclosed.

1. A gasket loop comprising: a gasket shape including a first portion characterized by a first cross-sectional view and a discrete number of second portions positioned around the gasket shape, wherein each discrete second portion is characterized by a second cross-sectional view,the first portion in the first cross-sectional view having: a substantially elongated body characterized by a width and a height;a first end characterized by a height, a tip, a width enlarged relative to the width of the body, and a tapered backside, wherein the tapered backside is integral with the body; anda distal second end connected to the body; andthe second portion in the second cross-sectional view having a tip and a height substantially matching those of the first end, and a body that is characterized by a width that is substantially equivalent to the width of the first end. 2. The gasket loop of claim 1, wherein the tip of the first portion in the first cross-sectional view is tapered. 3. The gasket loop of claim 1, wherein the distal second end of the first portion in the first cross-sectional view is substantially spherical. 4. The gasket loop of claim 1, wherein the gasket is formed from a compliant material. 5. The gasket loop of claim 1, wherein the gasket is configured to come into contact with a fluid, and the material is selected based on its chemical resistance to the fluid. 6. The gasket loop of claim 1, wherein the predetermined gasket profile is configured as multiple interconnected O-rings. 7. A fluid-pressure joint assembly comprising: a gasket loop having a gasket shape including a first portion characterized by a first cross-sectional view and a discrete number of second portions positioned around the gasket shape, wherein each of the second portions is characterized by a second cross-sectional view, the first portion in the first cross-sectional view having a substantially elongated body characterized by a width and a height, a first end characterized by a height, a tip, a width enlarged relative to the width of the body, a tapered backside, and a distal second end connected to the body, wherein the tapered backside is integral with the body, and the second portion in the second cross-sectional view having a tip and a height substantially matching those of the first end, and a body that is characterized by a width that is substantially equivalent to the width of the first end;a first component having a first surface and a channel loop arranged on the first surface to accept the gasket loop, wherein the channel loop is characterized by a channel height, and by a channel profile configured to complement the gasket shape, the channel additionally having a lead-in chamfer configured to complement the tapered backside, and wherein the first component additionally includes a first internal fluid passage having an exit on the first surface, such that exit of the first internal fluid passage is encircled by the channel loop; anda second component having a second surface and a second internal fluid passage having an exit on the second surface;wherein: when the gasket loop is inserted into the channel loop and the first component is assembled with the second component, the second surface is disposed substantially parallel to the first surface, the exit of the second internal fluid passage is encircled by the channel loop, and the second surface of the second component compresses the gasket loop against the first component, such that the height of the body of the first portion is compressed against the channel and the first end of the of the first portion is compressed against the lead-in chamfer to thereby seal the fluid-pressure joint. 8.
