A coupler (100) releasably couples a tube (50) to a threaded port (80). The tube has a circumferential bead (58) formed on one end to engage the coupler. The coupler includes a fitting (110) with a threaded portion (112) to threadedly engage the port. A central passage (130) extends through the fitting and is made up of a first cavity (132), a second cavity (136), and a third cavity (140). The second cavity has a larger diameter than the third cavity, which is at least partially surrounded by the threaded portion of the fitting. When inserted into the central passage, the tube extends at least partially into the portion of the third cavity surrounded by the threaded portion of the fitting. The coupler further includes a retainer (150) that engages the bead on the tube to limit movement of the tube relative to the retainer when the tube is inserted into the central passage. |
