ABSTRACT:
A quarter turn quick connect fitting assembly (10) for connecting miniature fluid conduits, such as tubing, includes a first fitting (12) having radially projecting pins (28) and a second fitting (14) located within a rotatable quarter turn nut (16) having spiral grooves (48) which receive the pins. The first fitting defines a central passage (26) and the second fitting defines a central passage (42) which may each be configured to slidably receive a hollow tube set (104), or to threadably receive an externally threaded mating fitting. The quarter turn quick connect fitting can be configured to attach to the end of a column, and can include an adapter (158), which houses a guard column (160), or a frit (188) for filtering the fluid passing through the quarter turn quick connect fitting assembly. The quarter turn quick connect fitting is assembled by sliding the pins of the first fitting into the grooves of the quarter turn nut and rotating the quarter turn nut through approximately 90.degree. with respect to the first fitting, thereby securely seating the pins within angled areas defined at the ends of the grooves.
