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

• a cap comprising an integral body, a closed end, an annular wall having a length LC extending from the closed end to an open end and defining a chamber, the open end defining an end face, the open end defining an engagement surface, the chamber comprises a first portion adjacent the closed end having a first portion inner diameter and a second portion adjacent the open end having a second portion inner diameter, the first portion and second portion in fluid communication with each other and the first portion inner diameter being less than the second portion inner diameter, the first portion containing an absorbent material and disinfectant or antimicrobial agent;
• the annular wall having an exterior wall surface and an interior wall surface;
• a peripheral ledge extending radially between the interior wall surface of the second portion to the interior wall surface of the first portion;
• an elastic sealing ring having a top surface and a bottom surface, the bottom surface disposed on the peripheral ledge, the elastic sealing ring extending radially inward from the interior wall surface, the elastic sealing ring having a dilatable opening therethrough sized and adapted to receive a male luer connector, a female luer connector and a hemodialysis connector, the dilatable opening sized to frictionally engage a male luer connector, wherein the peripheral ledge is disposed within the chamber and configured such that the male luer connector rests on the peripheral ledge upon being fully inserted in the chamber;
• the interior wall surface comprising internal threads adjacent to the closed end, the internal threads disposed adjacent the closed end and partially extend from the closed end to the peripheral ledge, the internal threads positioned within the chamber and sized to engage a female luer connector, wherein when a male luer connector, a female luer connector and a hemodialysis connector is inserted through the dilatable opening, the absorbent material and the disinfectant or the antimicrobial agent contact the male luer connector, a female luer connector and a hemodialysis connector;
• and
• a peelable seal on the end face to prevent the disinfectant or the antimicrobial agent from exiting the chamber.
