What does this fitting connect?

It joins a 6AN ORB (O-ring boss) port to a straight 6AN male flare line. That is the common port on Snow Performance pumps and tanks feeding a 6AN hose.

Is it the same as a 6AN hose end?

No. A hose end attaches to braided hose. This is an adapter that screws into an ORB port and gives you a 6AN flare to connect a hose end to.

Will it fit my Snow Performance kit?

It fits kits that use 6AN ORB ports. Check your pump or manifold thread before ordering, since some systems use 4AN or NPT instead.

Does it come with an O-ring?

ORB fittings normally ship with an O-ring, and the seal depends on it. Inspect the O-ring on arrival and replace it if it is nicked or flattened.

Can I use it on fuel lines?

The thread and flare are standard 6AN, so it can work on fuel or oil lines with matching ports. Confirm the aluminum is rated for your pressure and fluid before use.
