Abstract
Embodiments provide for a tube coupler for receiving and securely holding a tube. The tube may be inserted into an opening in an end cap, which engages a coupling body for axial movement between forward and retracted positions on the coupling body. By moving the end cap from the retracted position to the forward position, an end of the tube is drawn into the coupling body to engage and seal against an in-turned annular flange of a seal. Further, as the tube is drawn into the coupling body the seal is compressed around an outer surface of the tube to further seal the tube within the tube coupling.
