    Abstract: A reciprocating fluid pump includes a pump body, a subject fluid chamber, a first plunger located within the subject fluid chamber of the pump body and having a first head portion and a first bellows, the first plunger configured to expand and compress in a reciprocating action to pump the subject fluid through the subject fluid chamber within the pump body, wherein the first head portion and the first bellows have a first cross-sectional dimension, and a second plunger located within the subject fluid chamber of the pump body and having a second head portion and a second bellows, the second plunger configured to expand and compress in a reciprocating action to pump the subject fluid through the subject fluid chamber within the pump body, wherein the second head portion and the second bellows have a second cross-sectional dimension that is smaller than the first cross-sectional dimension.

    Abstract: A fitting assembly may seal a wire within a tube to inhibit ingress of fluid outside the tube into the tube and into contact with the wire. The fitting assembly may optionally include a body and a nut, with a part of the nut received within the body. The nut may be threadedly connected to the body, such that threading and/or unthreading the nut translates the part of the nut within the body. Optionally, the nut may include a ring extension that is received within a ring cavity of the body, and an interfacing between the ring extension and the ring cavity may create a seal to inhibit leaking of the fluid past the seal. A method of sealing a wire within a tube may comprise positioning a tube with a wire therein within such a fitting assembly.
