Abstract
A quick connect coupling includes a male coupling component and a female coupling component that axially interfit in a locked and unlocked relationship with each other with 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 has 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 disposed within the female coupling component has a tapered valve seat area that cooperates with a poppet valve. The valve seat member has a generally cylindrical body with a generally cylindrical inner surface adapted to receive a first end of said tubular stem portion, the valve seat member also having a generally cylindrical outer surface. The valve seat member includes a seal in a recess of the outer surface and a seal in a recess in an inner surface thereof. The tubular body extension is an unwetted part.
