If you want a correctly sized one, ignore the other brands and get this one! It seems like many brands (including a top selling one on Amazon) aren't actually making these to the AN6 sizing specifications of the AN standard. I bought two different brands before this one and both were larger than the AN6 specifications (verified that by using a caliper) and trying to screw on the fuel line would get stuck immediately upon starting to thread it, making you have to really force it on by literally tearing up the threads on the connector. This one is actually sized correctly and screws on as it should. I've had zero issues and would buy this one again in a heartbeat.

Used for my fuel pump from 6 o ring to 6AN fitting. No issues. Threads cut good and no leaking.

Great quality and product!

Worked perfectly in my Holley Sniper.

I used this during an LS Swap and it worked great!

Good product but didn't work for my project

Per the AN fitting specs, and AS568A o-ring spec a -6 AN ORB requires a #906 o-ring (0.468"x0.624" with a 0.078" cord thickness). This fitting comes packaged with a smaller #013 o-ring (0.426"x0.566" with a 0.070" cord thickness), this o-ring is 10% thinner unstretched and even more so when put around the fitting, this means that depending on how the receiving part is ported for the o-ring cavity it may end up leaking as the o-ring requires a certain amount of crush or squeeze to seal the fitting. I'm still giving 4 stars because the fitting is fine otherwise and sold at a decent price, i will just purchase a bag of #906 o-rings to correct the issue.

Works as it should.
