A device for connection to a medical connector, the device comprising:

• a cap comprising a closed end, an annular wall having a length extending from the closed end to an open end and defining a chamber containing an absorbent material and disinfectant or antimicrobial agent, the open end having a peripheral ledge extending radially from the open end defining an engagement surface;
• the annular wall having a frustoconical shape and further having an exterior wall surface and an interior wall surface;
• the interior wall surface defining an opening adjacent to the open end, the opening sized and adapted to receive a male luer connector, a female luer connector and a hemodialysis connector, the interior wall surface extending from the open end to the peripheral edge having a smooth interior wall surface leading to the peripheral ledge, wherein the male luer connector frictionally engages the interior wall surface via a press-fit connection upon insertion into the chamber and the wherein the male luer connector rests on the peripheral ledge upon being fully inserted into the chamber;
• the interior wall surface of the peripheral ledge leading to a portion of the interior wall surface comprising internal threads adjacent the closed end partially extending along a length of the interior wall surface, the internal threads adapted and sized to engage a female luer connector, the absorbent material and the disinfectant or the antimicrobial agent capable of contacting the male luer connector, the female luer connector and the hemodialysis connector;
• the exterior wall surface comprising a plurality of radial protrusions;
• a container comprising an annular container wall having a container wall length extending from a container closed end to a container open end face, the container having an interior container surface and an exterior container surface, the container housing the cap, the container having a complementary plurality of depressions that engage the plurality of radial protrusions;
• and
• a peelable seal on the container open end face to prevent the disinfectant or the antimicrobial agent from exiting the chamber.
