You can get them from any Merc or Sierra dealer.
You can get the Blue Plugs individually for cheap. I carry 1/2 dozen or so with me just in case one needs replacement. Some online places sell in lots of 4,5, or 6 for cheap. Most break because being overtightened. The Blue Plugs have an o-ring and are not pipe thread, therefore, only light pressure needed to seat. I also spray threads with WD-40 or similar.
Here are the Part#'s for pipe adapter and the plugs:
