That is the Master Adapter wpa SP sells. It's so versatile. It even works with the Splinter & the vapcap. It's on my w/l along with the a TM.

I have one and I've used it with the Grav Labs and stock stem as well as the RBT stems when I'm using my Milaana. It works really well and it's a nice little addition to my gear so I can always adapt to a bong. In the USA they're only $10 right now which is pretty good. Little more pricey north of the border.
