    摘要： A fitting assembly (1) comprises: a nut having a first end and a second end and having a first passageway therethrough, wherein the first passageway has a first portion with a first diameter and a second portion with a second diameter, with the second diameter larger than the first diameter, and wherein the first passageway is adapted to removably receive a portion of a tube therethrough and wherein the nut comprises a threaded portion adapted to removably engage with a flat-bottom port; a cylindrical transfer tube (72, 92) having a first end and a second end and having a second passageway therethrough, wherein the second passageway is adapted to receive a portion of the tube therein, wherein the tube is secured relative to the transfer tube, and wherein a first portion of the transfer tube is located within the second portion of the nut and a second portion of the transfer tube extends from the second end of the nut, and wherein the first end of the transfer tube abuts an interior portion of the nut; and a cylindrical tip (73, 83, 93) having a first end and a second end and having a third passageway therethrough, wherein the tip is secured relative to the tube, wherein an end portion of the tube is located within the third passageway, wherein the first end of the tip abuts the second end of the transfer tube, and wherein when the nut is engaged with the flat-bottom port, the nut exerts a force against the first end of the transfer tube such that the second end of the transfer tube exerts a force against the first end of the tip to seal the second end of the tip against the flat-bottom port.

    摘要： A tubing or fitting assembly has an inner tube layer, an outer tube layer, a sleeve, a tip portion, and can have a nut. Each of the nut, sleeve, inner and outer tubing layers, and tip portion have a passageway therethrough, with at least the passageways in the sleeve, tip portion, outer tube layer, and nut adapted to allow the inner tube layer to pass therethrough or extend over the inner layer. The tip portion can be molded over an end portion of the inner tube layer and also over a portion of the sleeve. The sleeve may include a retention feature in the form of a lip which extends into the tip portion, and also a narrower portion so that the tip portion and sleeve remain coupled together. The inner and outer tubing layers can also be retained by an interference fit. The ends of the tip portion and inner layer together define a substantially flat surface which can form a seal in a flat-bottomed port of a component such as may be found in any one of a number of components in an analytical instrument system, including for example a liquid chromatography system. The nut, tube, ferrule, and transfer tube or liner tube may comprise biocompatible materials. In addition, the nut may have a slot, such as a slot adapted to allow the tube and the nut to be easily and quickly separated or to allow a portion of the tube to be easily and quickly inserted in the nut.
