ABSTRACT:
A fluid connector (40) for gripping and sealing on an external surface of a fluid conductor (61). The fluid connector (40) includes a seal (62) which is forced into a bore (70) of a piston (66) having a smaller diameter than the seal, so that the seal (62) is radially squeezed to seal the external surface of the fluid conductor (61). A collet assembly (50) of the fluid connector (61) is forced to reduce the diameter to grip the external surface of the fluid conductor (61). A spring (68) which is disposed in the piston (66) compensates seal preload mechanism for variations in fluid conductor size.
