For anyone installing or repairing a direct vent system, this DuraVent pipe is exactly what you need. It's 24 inches long with a 4-inch inner diameter (6 5/8 inches outer diameter), made from galvanized steel that's built to last. The twist-lock construction is genius - no tools needed, just line up the arrows and twist to lock it in place. What's really nice is that you don't need sealant or gaskets (unless your appliance manufacturer specifically requires it). The connections are tight and secure, and there are no beads or hems, so it looks clean and professional when installed. I've used these for gas fireplaces, heaters, and stoves, and they've performed flawlessly. The low-profile locks mean you get a smooth appearance that works well in any interior space. When you're calculating your installation length, remember to subtract 1.5 inches for each joint to get the actual vent run. DuraVent (formerly Simpson Dura-Vent) is a leader in venting technology, and you can really see the quality in this product. Whether you're a professional installer or a DIY homeowner comfortable with gas appliance installation, this pipe makes the job straightforward and reliable. It's designed specifically for appliances tested and listed for direct vent use, so you know it meets all the necessary safety standards. The galvanized finish holds up well to heat and environmental conditions, making this a solid choice for both interior and exterior venting applications.
