6 Inch Oval-To-Round Adapter For Wood Stoves
Brand: LLPParts. This 24-gauge black adapter converts oval stove flues to 6-inch round pipe. The oval side measures 7-1/2″ x 3-1/2″ with an overall height of 9-1/4″, and the round side accepts crimped 6″ pipe. Best for installations needing a compact oval-to-round transition on standard 6″ rounds, especially when space around an oval flue is limited. The oval edge is crimped to fit snugly inside the stove’s oval collar. A one-year warranty adds peace of mind. Consider this if your system uses a GRAY METALS OEM oval collar and you need quick field installation.
Best for: Homeowners replacing a damaged oval-to-round section in a compact stove setup. Because it’s 24-gauge, it’s suitable for typical indoor stove installations but may be less ideal for external, harsh environments compared with heavier gauges.
Caution: Check your oval dimensions before purchase; the oval side is 7-1/2″ x 3-1/2″ and may not fit larger or differently shaped collars.

Brand: Imperial. This 6″ oval-to-round adapter provides a black finish for a seamless look in wood stove installations. It is designed to facilitate a direct transition from an oval flue to a round pipe, aligning with standard 6″ round duct.

Best for: Professionals or experienced DIYers seeking a straightforward oval-to-round connector from a trusted brand for standard 6″ round piping.
Best for: Systems prioritizing a clean, black aesthetic and a trusted brand. If you need a simple, ready-to-install adapter for a 6″ round duct, this is a strong choice.
Caution: Product features listed are limited; verify exact oval measurements and compatibility with your stove’s collar before purchasing.
For Imperial Stove Pipe Oval To Round Connector 4-1/4 x 9-1/2

Better for: 4-1/4″ by 9-1/2″ oval-to-round transitions—useful when your oval collar is narrower but must reach a standard 9-1/2″ round run. Caution: Ensure your oval dimension and round duct run match this connector size; misfit can lead to leaks or improper seating.

This is suitable for mid- to large-appliance installations.
Better for: Stoves or chimneys that rely on a bigger round pipe to improve draft or accommodate higher exhaust volumes. Caution: The data does not specify wall thickness beyond “highly durable”; confirm rigidity for your climate and installation still applies.

Buying Guide: Oval-To-Round Stove Pipe Adapters
What to consider when choosing
- Size compatibility: Match the oval outlet size to the round pipe you plan to connect. Common oval sizes around 7″ x 3.5″ or 7″ x 7″ transition to 6″ or 8″ rounds show up most often.
- Gauge and durability: Thicker gauges withstand more heat and physical contact in exposed installations. Heavier gauges are better for outdoor or long runs, while lighter gauges may suffice for indoor, short runs.
- Finish and fit: Black finishes are common for a clean look and corrosion resistance. Ensure crimped edges fit on the stove side for a secure seal.
- Warranty and support: A warranty and accessible customer support help with installation questions or component issues over time.
- Compatibility with stove system: Verify that the connector is designed for oval-to-round transitions and compatible with your stove model and chimney configuration.
How to measure for the right adapter
- Measure the oval collar on the stove: length by width (L x W) and the wall thickness if possible.
- Measure the target round pipe diameter you will connect to (commonly 6″ or 8″).
- Confirm the overall height and the crimped edge fit to ensure a tight seal without gaps.
Installation tips
- Clean and dry mounting surfaces before installation to maximize seal integrity.
- Use high-heat sealant or gasket material as recommended for your stove model and local code.
- Ensure proper clamping and alignment to avoid kinks or misalignment that could hamper airflow or create leaks.
