Fluid connector assembly

A method, comprising:

• in a connector assembly comprising:
• (i) a first connector comprising a first housing and one or more first pipes to flow fluid, (ii) a second connector comprising a second housing and one or more second pipes to flow the fluid, and (iii) a blocker disposed between the one or more first pipes and the one or more second pipes, and having one or more openings,
• mating the t first and second housings in a first position in which (i) the one or more first pipes are facing the one or more second pipes, respectively, but (ii) flowing of the fluid between the one or more first pipes and the one or more second pipes is blocked by the blocker;
• and
• switching from the first position to a second position by rotating about a longitudinal axis of the connector assembly, at least a first portion of the connector assembly relative to a second portion of the connector assembly, thereby aligning the one or more openings with the one or more first pipes and with the one or more second pipes, respectively, to enable the flowing of the fluid.
