Although they appear to fit the -6 fittings I have, they are not the standard -6 key size. If you have a set of AN wrenches other than mar and want to use these, don't buy them. Go for the Russell or the Aero Motive or the Summit or whatever. An 18mm wrench is used instead. I assume mm aluminum will do without mara. But cheer up! I haven't pressurized the fuel system yet. I bought them to hurry and of course hope they close properly. Edit: After receiving the an4 fittings as well as the ones that don't fit wrenches and the aluminum is soft and the anodizing gets damaged easily I decided to send them all back. They are no cheaper than good brands and the quality is terrible.
