The breakaway assembly includes a first breakaway subassembly and a second breakaway subassembly. The subassemblies are configured to connect, which causes bellows sheaths in each subassembly to compress and open pores, allowing fluid to flow through the subassemblies. The subassemblies can be connected to luer tip. The luer tips can be connected to the an intravenous (IV) fluid line or other types of lines used in the medical field to move fluids. This allows the movement of fluid from a fluid-holding component to a patient. Unless the subassemblies are locked together, the subassemblies will be disconnected under the correct amount of pressure. This disconnection closes the pores on the subassemblies, which keeps fluid from leaking, and prevents the contamination of the IV line. Luer tips may also be connected to the subassemblies. Some of the luer tips allow for the quick connection of the luer tip to the subassembly through a flange being inserted into a notch or flange acceptor. This allows for the quick and easy replacement of components of a fluid transfer assembly.
