5" Oval Double Ply Smooth Chimney Liner Kit

The 5 Inch Oval Double Ply Smooth Chimney Liner Kit is a premium stainless steel chimney liner designed for installations where a standard round liner will not fit. Made from high-quality 316 stainless steel, this liner kit is ideal for relining masonry chimneys while protecting against corrosion, moisture, and flue gas leaks.

This 5 inch oval chimney liner kit is commonly used for smaller wood stoves, fireplace inserts, and residential heating appliances that require a 5" flue. It is specifically designed for installations where a properly sized round chimney liner cannot fit inside the existing chimney due to limited space. Its oval shape allows for proper airflow while fitting into tight or rectangular flue tiles.

The double-ply smooth wall construction improves draft efficiency and airflow compared to corrugated liners, while also making cleaning easier. This design provides increased strength and durability while maintaining flexibility for installation in masonry chimneys.

If a properly sized round chimney liner cannot fit inside your flue, an oval chimney liner provides a safe and effective alternative without sacrificing performance.

Key Features: 5" oval sizing (outside dimensions vary), double-ply smooth flexible construction, .006" wall thickness, 316 stainless steel, UL 1777 listed, made in the USA, air- and water-tight design, 7-ply seams, and lifetime warranty.
