A system for establishing a fluid path between a plurality of tubes includes a manifold and a plurality of caps. The manifold defines an internal cavity and a plurality of orifices that access the cavity. Each of the plurality of caps are secured to an end of a respective tube of the plurality of tubes. Each cap defines a central orifice that is in fluid communication with the respective tube. Each cap has a tapered protrusion extending away from the end of the respective tube. The caps are disposed within the internal cavity such that the respective tube extends through a respective orifice of the plurality of orifices and outward from the manifold. The tapered protrusions of adjacent caps interact with each other to position each cap to form a seal with other caps having a central orifice such that the central orifices are in fluid communication with each other.
