The first conduit defines a first open end. The first open end is configured to connect to a first external component and establish fluid communication between the first conduit and the first external component. The second conduit defines a second open end. The second open end is configured to connect to a second external component and establish fluid communication between the second conduit and the second external component. The bend extends between the first and second conduits. The bend defines a channel extending between the first and second conduits. The channel establishes fluid communication between the first and second conduits. The bend has a ramped surface that at least partially defines the channel and extends between the first and second conduits. The bend orients the first conduit at an angle relative to the second conduit. ## Claims ### Claim 1 An elbow connection comprising: a first conduit having a first open end, wherein the first open end is configured to (i) connect to a first external component and (ii) establish fluid communication between the first conduit and the first external component; a second conduit having a second open end, wherein the second open end is configured to (i) connect to a second external component and (ii) establish fluid communication between the second conduit and the second external component; and a bent region (i) extending between the first and second conduits, (ii) defining a channel extending between the first and second conduits, wherein the channel establishes fluid communication between the first and second conduits, (iii) having a ramped surface that at least partially defines the channel and extends between the first and second conduits, wherein the ramped surface tapers (a) laterally inward along a first direction that extends from a middle of the bent region and toward the first open end and (b) laterally inward along second direction that extends from the middle of the bent region and toward the second open end, and (iv) orienting the first conduit at an angle relative to the second conduit, wherein the angle is less than 100° and greater than 90°. ### Claim 2 (depends on 1) The elbow connection of claim 1, wherein the bent region includes a radially inward section and a radially outward section, and wherein the ramped surface is positioned internally on the radially outward section. ### Claim 3 (depends on 1) The elbow connection of claim 1, wherein the ramped surface (i) extends between first and second ends and (ii) terminates at the first end and along the first conduit, wherein the first end is spaced-apart from the first open end. ### Claim 4 (depends on 3) The elbow connection of claim 3, wherein the ramped surface terminates at the second end and along the second conduit, wherein the second end is spaced-apart from the second open end. ### Claim 5 (depends on 1) The elbow connection of claim 1, wherein the angle is substantially 95°. ### Claim 6 (depends on 1) The elbow connection of claim 1, wherein (i) an internal diameter of the first conduit is greater along a first region that includes and is adjacent to the first open end relative to a remainder of the first conduit, (ii) an internal diameter of the second conduit is greater along a second region that includes and is adjacent to the second open end relative to a remainder of the second conduit, and (iii) clips extending from the first region are configured to engage corrugated tubing. ### Claim 7 (depends on 6) The elbow connection of claim 6, wherein the second region defines aligned orifices configured to receive a pin to secure the second conduit to the second external component. ### Claim 8 An elbow connection comprising: a first conduit defining a first opening configured to establish a first fluid connection; a second conduit defining a second opening configured to establish a second fluid connection; and a bend (i) extending between the first and second conduits, (ii) defining a channel establishing fluid communication between the first and second conduits, and (iii) having a ramped surface at least partially defining the channel and extending between the first and second conduits, wherein the ramped surface tapers (a) laterally inward along a first direction that extends from a middle of the bend and toward the first opening and (b) laterally inward along second direction that extends from the middle of the bend and toward the second opening. ### Claim 9 (depends on 8) The elbow connection of claim 8, wherein (i) the bend orients the first opening at an angle relative to the second opening and (ii) the angle is substantially 95°. ### Claim 10 (depends on 8) The elbow connection of claim 8, wherein (i) the bend orients the first opening at an angle relative to the second opening and (ii) the angle is less than 100° and greater than 90°. ### Claim 11 (depends on 8) The elbow connection of claim 8, wherein the bend includes a radially inward section and a radially outward section, and wherein the ramped surface is positioned internally on the radially outward section. ### Claim 12 (depends on 8) The elbow connection of claim 8, wherein the ramped surface (i) extends between first and second ends and (ii) terminates at the first end and along the first conduit, wherein the first end is spaced-apart from the first opening. ### Claim 13 (depends on 12) The elbow connection of claim 12, wherein the ramped surface terminates at the second end and along the second conduit, wherein the second end is spaced-apart from the second opening. ### Claim 14 (depends on 8) The elbow connection of claim 8, wherein (i) an internal diameter of the first conduit is greater along a first section that includes and is adjacent to the first opening relative to a remainder of the first conduit, (ii) an internal diameter of the second conduit is greater along a second section that includes and is adjacent to the second opening relative to a remainder of the second conduit, and (iii) the first section defines aligned orifices configured to receive a pin to secure the first conduit to an external component. ### Claim 15 (depends on 14) The elbow connection of claim 14 further comprising clips extending from the second section, wherein the clips are configured to engage corrugated tubing. ### Claim 16 A conduit comprising: a first region extending along a first axis; a second region extending along a second axis; and a bend (i) extending between the first region and the second region, (ii) defining a channel establishing fluid communication between the first and second regions, (iii) orienting the first axis at an angle relative to the second axis, and (iv) having a ramped surface that at least partially defines the channel and extends between the first and second regions, wherein the ramped surface tapers (a) laterally inward along a first direction that extends from a middle of the bend and toward the first region and (b) laterally inward along a second direction that extends from the middle of the bend and toward the second region. ### Claim 17 (canceled) ### Claim 18 (depends on 16) The conduit of claim 16, wherein the bend includes a radially inward section and a radially outward section, and wherein the ramped surface is positioned internally on the radially outward section. ### Claim 19 (depends on 16) The conduit of claim 16, wherein the ramped surface (i) extends between first and second ends and (ii) terminates at the first end and along the first region, wherein the first end is spaced-apart from an open end of the first region. ### Claim 20 (depends on 19) The conduit of claim 19, wherein the ramped surface terminates at the second end and along the second region, wherein the second end is spaced-apart from an open end of the second region. ### Claim 21 (depends on 16) The conduit of claim 16, wherein the angle is substantially 95°.
