A medical coupling device manufactured from a device material provides an secure friction fit to a male nozzle device. To that end, the medical coupling device includes a fluid port (with an inner periphery) for receiving a male nozzle with a nozzle outer diameter, and a coupling material having a coupling material frictional value that is greater than the device material frictional value. The coupling material preferably is disposed about the inner periphery of the fluid port, while it and the inner periphery form an opening having an opening inner diameter. The opening inner diameter preferably is sized to receive and secure the male nozzle. The device material frictional value preferably is lower than the coupling material frictional value.
