The 0700Q-xx assembly includes a short tube for the fogger power head, a quick connect fitting, tubing to length and a 0700-xx flow restrictor liquid entry. The quick connect fitting makes it easy to change restrictor size, and flow rate and fog droplet properties. Just unscrew the twist lock fitting, remove the old assembly, transfer the dust cap, and screw on the new assembly. To add a flow restrictor to a standard 6309 or 6329 fogger, purchase a 0700Q-xx (as a part) and install it in place of the original liquid inlet assembly.
