Description
The Superior 18-8HT 18" Snap Lock Section Double Wall Pipe is a durable and efficient chimney component designed for use in compatible wood-burning fireplace venting systems. Featuring a double-wall construction, this chimney section includes a 12-3/8-inch diameter galvanized outer pipe and an 8-inch diameter stainless steel inner flue pipe. A built-in wire spacer separates the two walls, helping maintain proper insulation and structural stability while supporting efficient draft performance. This rugged design enhances durability and helps the chimney system withstand the high temperatures associated with wood-burning applications.
Designed with a secure snap-lock connection system, the Superior 18-8HT allows for quick and reliable installation while ensuring a stable connection between chimney sections. When designing or extending a chimney system, installers should account for lineal gain, which refers to the actual measurable length achieved after overlapping and connecting multiple components. Understanding lineal gain is essential for accurate chimney height calculations and proper venting system configuration. Manufactured to Superior’s high-quality standards, the 18-8HT Double Wall Pipe delivers dependable performance, long-lasting durability, and efficient venting. It is an excellent choice for new installations, chimney extensions, or replacement projects requiring reliable chimney system components.
