Pasco 1688 – Frequently Asked Questions
1) Will the Pasco 1688 flexible duct connect to standard 4 inch vent fittings and terminations?
Yes. The Pasco 1688 is a 4 inch diameter flexible aluminum duct, sized to mate with standard 4 inch venting and duct fittings, transitions, and vent terminations. It can be cut to length on site, so you can trim a run down and still land on a 4 inch collar or cap.
2) How long is one piece of Pasco 1688 duct, and can I run it through joists and a tight wall cavity?
Each piece is 4 inches by 8 feet. The Lama-style aluminum flexible construction bends and compresses through framing, joists, and tight wall cavities without kinking the way rigid pipe would, which is why it gets used for rough-in runs behind the wall. For runs longer than 8 feet you will need multiple pieces and a coupling.
3) Do I have to buy a full case of the Pasco 1688 aluminum duct, or can I order one?
Minimum order is 1 each, so you can take a single length. Case quantity is 144 each if you are stocking a truck or a distributor shelf for repeat rough-ins.
4) Is the Pasco 1688 duct aluminum or foil-faced flex, and will it corrode?
The 1688 is an aluminum flexible duct body. Aluminum resists corrosion and holds up to repeated flexing during installation, which is what makes it suited to behind-the-wall rough-in and light HVAC or venting runs rather than exposed rigid pipe.
5) Does the Pasco 1688 flexible duct carry a California Prop 65 warning?
Yes, the 1688 aluminum flexible duct is flagged with a Prop 65 warning. If you are a procurement buyer who has to document Prop 65 items for a California facility or jobsite, record it against this part.
