Copied from a guy’s post at bf.c. Thought it might be handy info for someone some day.
I found the valves at McMaster Carr
below are the replacement connector part numbers with barbed ends and valves:
5923K73 (male)
5923K43 (female)
For draining the hose and shirt, you need connectors without valves. For the tube, you need a male and female connector. For the shirt, you need 2 female connectors. I used connectors with a screw coupling in lieu of the barb for purposes of more flow. These part numbers are:
51545K66 (male)
51545k13 (female)
