• a main body extending along a primary axis and defining a lumen, the lumen extending between a lower mouth at a lower portion of the main body and an upper mouth at an upper portion of the main body;
• a first mating portion;
• and
• a second mating portion;
• wherein the first mating portion and the first port are configured to engage each other such that the lower mouth of the connector extends a predetermined distance into an interior of the medical waste fluid collection system when the connector is connected with the first port;
• and
