Abstract
System, apparatus and method for opening a heat-bonded connection formed between two hollow, flexible thermoplastic conduits. A pressure difference is created between the inside of at least one of the conduits and the ambient atmosphere sufficient to cause expansion of a wall of the tubing conduit in the vicinity of a frangible portion at least partially blocking the connection to disrupt the frangible portion and reduce the blocking.
