Polyurethane feeding tube and associated adaptors

A feeding tube assembly comprising:

• a feeding tube adaptor made of polyurethane, the feeding tube adaptor including an elongated first inlet conduit having an inlet port, the feeding tube adaptor also including an outlet conduit for fluid communication with an inlet conduit of a feeding tube;
• and
• a cap made of polyurethane removably attached to close selectively the inlet port of the first inlet conduit, the cap having a surface with a surface configuration such that a portion of the surface engages a portion of a corresponding surface of the first inlet conduit, the surface configuration of the cap being noncomplementary to a corresponding surface configuration of the first inlet conduit in a common transverse plane such that the cap frictionally closes the inlet port of the first inlet conduit, wherein the surface configuration of the cap defines a cross-sectional shape different than that of the corresponding surface configuration of the first inlet conduit in the common transverse plane.
