Stainless steel oval to round chimney adapter for connecting dissimilar flue shapes

The oval to round adapter is a functional component designed to connect a chimney section with an elliptical (oval) cross-section to a round flue. This adapter is used in installations where a shape transition is required to connect different types of chimney systems or appliances.

Made from high-temperature resistant stainless steel (AISI 304L/316L), the adapter ensures a gas-tight and mechanically stable connection between the oval and round sections. It helps maintain the chimney’s performance and integrity while adapting to different geometries. Custom sizes and configurations are available upon request, including options with offset connections or flanged ends.

Key features and benefits

• Shape transition: Connects oval (elliptical) flue sections to standard round liners or rigid ducts.
• Secure connection: Provides a stable, airtight link between different parts of the chimney system.
• Durable material: Manufactured from high-grade stainless steel AISI 304L/316L, resistant to heat and corrosion.
• Custom solutions: Non-standard adapters available upon request, including flanged, offset, or extended configurations.
• Versatile applications: Ideal for chimney relining, equipment adaptation, or ventilation system transitions.
