Abstract:
1. A fluid path leakage prevention apparatus comprising: a tubular section comprised of a first material providing a fluid path; a transition piece comprising a material which is positive bondable or weldable to the first material and having a proximate and distal end, the proximate end connected to the tubular section, the distal end having a mating interface and an adapter end; and a circumferentially actuated flexible check valve comprising silicone and having a lip portion at one end and a mouth portion comprising two or more flexible members at the other end, the check valve being connected to and extending outwardly from the distal end of the transition piece and operatively connected to the fluid path, the lip portion extending radially outwardly from the check valve and being sealably disposed within the mating interface of the transition piece, the adapter end encompassing the lip portion and permanently locking the lip portion in sealed engagement with the mating interface, wherein the circumferentially actuated flexible check valve substantially prevents removal of a pressurized fluid in the fluid path during a non-actuated period.
