Quick connect coupling

A quick connect coupling comprising:

• male coupling component and a female coupling component that axially interfit in a locked and unlocked relationship with each other,
• the female coupling component having a hollow body, a tubular body extension that extends axially from a first end of the hollow body and a valve element that can translate along a longitudinal axis of the quick connect coupling;
• the male coupling component having a tubular stem portion that translates the valve element when the quick connect coupling is fully assembled to a locked position;
• a valve seat member slideably received within the female coupling component;
• said valve seat member having a generally cylindrical body with a generally cylindrical inner surface adapted to receive a first end of said tubular stem portion, and said valve seat member having a generally cylindrical outer surface;
• said valve seat member inner surface at one end thereof having a tapered valve seat area that cooperates with the valve element;
• a first recess formed in said valve seat member inner surface, a first seal disposed in said first recess;
• a second recess formed in said valve seat member outer surface, and a second seal disposed in said second recess;
• said tubular body extension being an unwetted component.

In a quick connect coupling of the type having a male coupling component and a female coupling component that interfit in a locked and unlocked relationship with each other, the female coupling component comprising:

• a hollow body, a tubular body extension that extends from a first end of the hollow body and a valve element that can translate along a longitudinal axis of the quick connect coupling;
• a valve seat member slideably received in the female coupling component, said valve seat member having a generally cylindrical body with a generally cylindrical inner surface adapted to receive a first end of the male coupling component tubular stem portion, and said valve seat member having a generally cylindrical outer surface;
• said valve seat member inner surface at one end thereof having a tapered valve seat area that cooperates with the valve element;
• a first recess formed in said inner surface, a first seal disposed in said first recess;
• a second recess formed in said outer surface, and a second seal disposed in said second recess;
• said tubular body extension being an unwetted component.
