Abstract
Two unique quick connect fluid coupling embodiments have a tube inner end which does not contact a seal if the tube is not fully connected. Preferably, a retainer retains the tube within the bore. The retainer is of the avalanche type such that a high force is required to insert the tube, and once this high force is overcome the momentum of the tube carries it to its fully inserted position. No seal is formed between the tube and seals within the housing unless the tube has moved beyond the avalanche point where the high force begins. Once the tube has moved beyond that point, it will be fully connected. The invention ensures that there would be no seal between a tube and a housing unless the tube is fully connected.
