Removable seal device for fluidic coupling

A fluidic coupling for use in a chromatography system comprising:

• a fluidic tube including an end surface, wherein the fluidic tube includes a support feature fixed to the fluidic tube proximate the end surface;
• a compression screw having a main body extending along an axis from a first end to a second end, the compression screw including a compression screw threaded portion configured to engage with internal threads of a receiver fitting, the compression screw including an opening extending from the first end to the second end along the axis, wherein the fluidic tube is configured to extend through the opening;
• and
• a removable seal device for fluidic coupling including 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 device is configured to be removably secured to at least one of the fluidic tube, the 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 support feature has a greater diameter than the fluidic tube, the support feature configured to abut the first end of the compression screw, the support feature including a support feature threaded portion, and wherein the threads of the internal surface of the seal body are configured to engage the threaded portion of the removable seal device,
• 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.
