The bags they are on are the labels of the product. Says the same thing on the receipt. The bottom one didn't come with a compression nut of any type. I was looking online and couldn't find a match from your write up you wrote. I figure a picture, if possible, would steer me the right direction. Then again to have you reply is a good thing see as you are the man himself.
Edit: i found some on amazon, but if I can I would rather buy it locally than have it shipped. http://www.amazon.com/dp/B000LNKE9S/ref=biss_dp_t_asn
