These are those hard to find metric threaded straight position macroline fittings you looked for everywhere but could not find. If you want to make the change from stainless line or simply replace the old metric threaded fitting of your Spyder, this is the one you'll need. The conventional 1/8" NPT fittings you've found elsewhere just won't do. They are nickel plated and straight from the factory so you'll rest assured they are pressure rated safe for paintball marker applications.
