1. A removable seal device for fluidic coupling for use in a chromatography system comprising:
a seal body extending between a first end and a second end, the seal body including an inner channel configured to receive a flow of a fluid, wherein the first end of the seal body includes a first sealing surface configured to create a first seal with a fitting sealing surface of a receiver fitting, and wherein the seal body incudes a second sealing surface configured to create a second seal with an end of a fluidic tube, wherein the removable seal is configured to be removably secured to at least one of the fluidic tube, a support feature fixed to the fluidic tube, and a compression screw, such that untightening of the compression screw from the receiver fitting causes the removable seal device to be removed from the receiver fitting,
wherein the seal body includes a cylindrical portion extending from the first end, and a conical portion extending from the cylindrical portion and expanding in diameter as the conical portion extends from the cylindrical portion,
wherein the cylindrical portion includes an internal bore dimensioned to receive the end of the fluidic tube and a length of the fluidic tube,
the seal body further including an internal surface within at least one of the conical portion and a cylindrical extended portion of the conical portion, the internal surface including threads configured to facilitate the removably securing to the at least one of the fluidic tube, the support feature fixed to the fluidic tube, and the compression screw; and
a metallic support sleeve surrounding the cylindrical portion configured to support the seal body.
