Smc fittings are the manufacture, look up miniature fittings, speciality fittings, m series fittings. You will be better off looking at the part number page because they do not list parts by picture. But rather by part number so you have to know what you want.
If those links don't work let me know, I'm on phone so not too easy to share info
.
Oh and a bag of ten is how they sell most fittings, but that bag of ten is cheaper than one from those other stores, or relative close to ,, forget actual price difference. But well worth having to purchase ten.
