I watched the video at Williams. I think I love these taps. I might consider switching from the Perlicks. At the very end of the info, that guy talks about some very cool attachments like bottling filling (with a gas attachment), Teflon-coated spout for no-drip pouring, stout spout. I'd probably switch to their shanks so I could use that auto-close spring, too.
The only downside is that they're not US made. I admire companies like Vent-Matic that stick to US manufacturing. I don't mind paying more for that, but the Vent-Matic site doesn't mention all these cool add-ons that the threaded spout allows.
I wonder if they threads on the spout of the Vent-Matics will take the attachments from Intertap?
