Product details:
This DuraLiner Oval Rigid Pipe is 6" in diameter and is constructed from 0.016" 304 alloy stainless steel. It is especially designed to resist the buildup of creosote in oversized masonry chimneys that vent open fireplaces or appliances. Both rigid and flexible sections of DuraLiner connect easily with pre-fitted ends and the rigid pieces come pre-insulated by the factory.
