12", 14", 14.5", and 15" Oval Single Ply Chimney Liner (Only)

The 12", 14", 14.5", & 15" Oval Single Ply Chimney Liner is a premium stainless steel chimney liner designed to improve chimney performance, safety, and durability in installations where a round liner will not properly fit. Manufactured from high-quality 316 stainless steel, this oval chimney liner is ideal for relining large masonry chimneys with limited space while protecting against corrosion, moisture, and flue gas leaks.

These large oval single ply chimney liners are commonly used for commercial fireplace systems, large wood stoves, boilers, furnaces, and other high-output heating appliances requiring an ovalized venting solution to fit narrow or offset chimney flues. Their oval design maximizes available chimney space while maintaining strong draft and airflow performance.

The single-ply flexible construction allows the liner to navigate bends and offsets within masonry chimneys while maintaining strength and long-term reliability. Its lightweight design simplifies installation while still delivering excellent durability.

Single-ply oval chimney liners provide a cost-effective and efficient solution for chimney relining applications where traditional round liners may not fit properly.
