Humidity in the air, as well as compressing air heats it up allowing the air to hold more moisture. It's why air compressor tanks have drains and most compressed air systems have water traps.

Most hardware store/plumbing are going to be SBR or Buna N (Nitrile) and more than adequate. Auto parts may have a Viton (FKM) for fuel applications, but would be overkill for a pump.

They actually look decent. How well they hold up or do their job, is not a concern since you are passing the bike along.
