These are "low point" drains. Does the blue one have threads where it is tapered? If not the entire fitting fell off. It should have exactly the same setup as the red one.
If you are just missing the cap they are easy to find. A white PVC 1/2 inch NPT threaded cap will get you up and running in no time.
If not you will need a PEX tubing to 1/2 inch NPT MALE fitting and cap
