When it comes to securing your home, every detail matters, especially the chimney system you rely on to keep your space warm and cozy. Introducing the DuraVent DuraTech 7" Stainless Steel Chimney Pipe - a masterpiece of safety and performance that ensures you have peace of mind, all year round.

With DuraTech, you're investing in a double-wall chimney system that meets the stringent UL 103 HT and ULC S604 standards. Its remarkable Thermal Tech blanket insulation nestled between dual walls offers the ideal blend of safety and performance. It keeps the exterior of the chimney cool while maintaining high flue gas temperatures, ensuring impeccable draft performance.

What sets DuraTech apart is its 25% thicker inner wall, providing an additional layer of safety without the need for locking bands or mechanical fasteners. Installation is a breeze thanks to the sleek 1" wall design, allowing easy placement through 16" on-center framing. For tighter spaces, our Reduced Clearance Square Ceiling Support Box is a game-changer, designed exclusively for 6" diameter DuraTech.

DuraTech has been engineered for normal, continuous operation at 1000°F flue gas temperatures and subjected to rigorous testing, including one hour at 1400°F and three ten-minute chimney fire tests at a scorching 2100°F. With DuraTech, you're investing in the ultimate safety for your home.


  • Versatile Compatibility: DuraTech fits seamlessly with wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, and other appliances powered by wood, oil, coal, or gas. It's also perfect for zero-clearance fireplaces that come factory-built.

  • Superior Materials: Crafted with precision, the 7" diameter pipe boasts an inner wall made from 0.020” 430 stainless steel, while the outer wall offers options of 0.016” 430 stainless steel or 0.021” galvalume steel. Refractory insulation is expertly encased between these walls, and stainless steel end rings seal the deal.

  • Effortless Installation: Say goodbye to the hassle of locking bands and mechanical fasteners. DuraTech features twist-lock fittings, support boxes with factory-installed starter sections, elbows with a 360° swivel base, select black finish pipe lengths, five-foot pipe sections, and adjustable pipe lengths for a smooth installation process.

  • Safety First: DuraTech boasts a 2" clearance to combustibles, ensuring your home's security. Our shroud specs even allow you to create a UL-listed shroud to conceal the termination at the chase's top for the safest installation.

  • Wide Variety: Choose from a wide array of diameters and lengths to suit your specific needs.

  • Installer-Friendly: The swivel base simplifies elbow alignment, saving you time and money. Get an offset and return elbow along with an elbow support bracket to ensure a code-approved offset installation.

  • Lifetime Peace of Mind: DuraTech comes with a Limited Lifetime Warranty, providing unmatched assurance. 15 years at 100% coverage, and beyond that, up to 50%. It's the best warranty in the industry, offering the greatest peace of mind for both installers and homeowners.
