Just to make it clearer...if I got the 14mm Sherlock...I would have to get this as well? Not sure about all the male-female stuff. The Sherlock hook is female too. It's a little confusing...I was under the impression that you could just connect the hook directly to the nano...
GRAV® reduction adapters decrease the diameter of a joint, making water pipes compatible with smaller accessories. This adapter changes a 19mm male joint into a 14mm female joint.

Hey man! So I don't have an E-Nano, or any log for that matter........not even sure how I ended up in this thread to be honest, lol...........but I used to have the hardest time with all these male/female adapters and such. But after awhile I realized what I was making confusing was actually insanely simple when you think about it.
Here's a link to what I'm talking about:
Will fit into a 14mm female glass joint on one side. and a 14mm male glass joint on other.

Ok, soooooooo, just think of the human anatomy and how it could pertain to these adapters. In the link, the bottom portion is basically a straight tube........like a male anatomy. And the top female portion has the opening that a male side can slide into. Sorry to be so gutterish, but that's what helped me finally figure it out, lol.
Edit: Or you can just do what CanikUser says and call it a day! But if this helps you figure it out then that's cool too!
