4.5" To 3.5" Stainless Steel Reducer Exhaust Pipe – Flue / Woodburner / Truck Adapter – Universal Joiner

Need to connect two different sized pipes?

This is a simple, no-frills stainless steel reducer.

It goes from a 4.5-inch diameter down to a 3.5-inch diameter.

It's perfect for exhaust systems, wood burner flues, or truck pipes – basically any situation where you need to join a larger pipe to a smaller one.

It's brand new, unbranded, but it's made of stainless steel, so it's durable and rust-resistant.

No manufacturer part number needed; it's just a solid, functional adapter.

If you've got a 4.5\ pipe and need to step it down to 3.5\, this is your part.
