A fair bit of a mouthful when you try repeat the title, but the Quick-Nut SST is essentially just a full boom system with fittings, light-weight stainless tubing, and pretty much everything south of the pump that you'd need to setup your boom.

By all means ask if you have any questions about the boom fittings and system. That's why I'm here.
